Howto setup Folding@Home

[COLOR="Red"]This first post is outdated, please see: https://help.ubuntu.com/community/FoldingAtHome and https://help.ubuntu.com/community/FoldingAtHome/Install[/COLOR] _________________________________________________

• [COLOR=red]I should note this howto is geared to 1 cpu however multi-cpu systems can still use this howto. But each cpu in multi-cpu systems must have it's own machine id[/COLOR].
• [COLOR=red]Laptop users are encouraged to see the **Folding@Home wiki** for special information. I don't use an laptop so that info probably will not show up here[/COLOR].
• For information on the issue of Intel HT cpu's (HyperThreading) see this post at the stanford forums

This is a howto for Folding@Home on Ubuntu. Works great on Breezy-5.10 & Dapper-Drake-6.06.

Is Folding@Home for you? (Old & New Computers welcome) It is a distributed computing project to understand protein folding, misfolding, and related diseases. It is run by or associated with (not sure) Stanford University. This software will benefit best if you leave your computer on 24/7. However the computer does not actually need to be on 24/7 however it will take a longer time to complete the job and if the time is long enough then you may miss the due date there by causing the WU (work unit) to be reasigned to someone else and causing delays. Remember that this project is about getting work units back to the researchers as fast as possible. So at the very least 4 to 6 hours a day of operation.

[COLOR=blue]Step 1.[/COLOR] Do not download the folding@home executable from the folding.stanford.edu website. Actually you can download it if you really want. Just run the script first to create the proper folders and then place the Folding@Home executable in No sudo [COLOR=green]/home/username/opt/foldingathome/config[/COLOR] With sudo [COLOR=red]/opt/foldingathome/config[/COLOR]

However I recomend that you download the single install script to your/home/username directory. If the link below ever stops working just get the file from the **wiki**.

File:<removed link per OP's request> [COLOR=red]Click on the link ^ to download[/COLOR]

[COLOR=blue]Step 2.[/COLOR] Extract the archive in your /home/username directory

• Do this by opening your terminal. In Gnome this is Applications/Accessories/Terminal.[COLOR=blue]KDE[/COLOR] and others you need to find and open your terminal version. For those that don't have X or boot directly to console I'll assume you know what to do.

[COLOR=red]Replacing "fah_install-version" with the current name.[/COLOR]

tar zxvf fah_install-version.tar.gz

CLIENT_OPTS='-forceasm'

[COLOR=blue]Step 3.[/COLOR] Navigate to the new folder in /home/username/folding and read the documentation.

cd fah_install
less README

[COLOR=blue]Step 4.[/COLOR] Install the Folding@Home client. Please note that if you don't have root access (su or sudo) you can't use sudo or su, so in that case just use the command without sudo or su.

[COLOR=red]Install command[/COLOR]

sudo ./folding_install.sh install

At this point you will be asked if you want to install to the system or user. Remember that if you don't have root (su or sudo) access to the computer you will need to choose user (1). Note that I personally strongly recomend that if you have root access (su or sudo) to your computer that you choose number (2) "system".

[COLOR=blue]Step 5.[/COLOR] Configuring the client. The client will ask you some questions and you will give it some answers to optimize it for your computer. Note that defaults will be shown in brackets [] and you may just hit enter to accept defaults.

• User name [Anonymous]? Make up one.
• Team Number [0]? Only if you want to be a part of a team. However I recommend that you join team [COLOR=red]"TeamUbuntu"[/COLOR] just enter the number [COLOR=red]45104[/COLOR].
• Ask before fetching/sending work (no/yes) [no]? Best to say no here.
• Use proxy (yes/no) [no]? Most people will probably say no here. If not just enter your proxy info.
• Allow receipt of work assignments and return of work results greater than 5MB in size (such work units may have large memory demands) (no/yes) [no]? Less than 1GB RAM no, 1GB or more yes. Remember you need to take into account your operating system and programs. Large units can exceed 500MB in ram requirements. Also if you are on dial-up modem service you should say no here.
• Change advanced options (yes/no) [no]? Type no here if you want to keep it simple.[COLOR=blue]Step 5a.[/COLOR] Advanced options
• Core Priority (idle/low) [idle]? Type idle here. There is no benefit to putting in low and in fact could actually interfere with your computers operation.
• Disable highly optimized assembly code (no/yes) [no]? Type no here
• Interval, in minutes, between checkpoints (3-30) [15]? I chose 30. This is how often to save the state. You should enter 3 to 5 minutes if you have a notebook or laptop, I myself use a desktop on battery backup. If you reboot, shutdown or crash and your state has not been saved your computer has to start over from the last saved state.
• Request work units without deadlines (no-pref/no/yes) [no-pref]? If you have an older computer or a computer that's not on all the time you might want to choose yes here.
• Ignore any deadline information (mainly useful if system clock frequently has errors) (no/yes) [no]? Type no here. But from time to time make sure your computer clock is fairly accurate.
• Machine ID ( 1-8 ) [1]? Type 1 here. [COLOR=red]If you have a multi-cpu system then each cpu must have it's own machine id. It is very important to make sure that under the "Advanced Settings" option each copy is given a unique machine ID ( from 1 to 8 ). The first copy (cpu 1) will default to a machine ID of 1, so additional copies should be given IDs of 2 (cpu 2), 3 (cpu 3), 4, etc[/COLOR].

[COLOR=blue]Step 6.[/COLOR] The install script will now tell you the command to start Folding@Home

[COLOR=green]If you did not use sudo, then use this command[/COLOR]. Note you still need to enter this command even if you chose to install the cronjob to be absolutely sure it is started as it gives immediate feedback.

/home/username/opt/foldingathome/foldingathome start

[COLOR=red]If you did use sudo, then use this command[/COLOR].

sudo /etc/init.d/foldingathome start

sudo /opt/foldingathome/reconfigure.sh or if you did not use sudo home/username/opt/foldingathome/reconfigure.sh or sudo ./folding_install.sh update

[COLOR=blue]Step 7.[/COLOR]  Once you are done entering the command open up in Breezy-5.10 **Applications>System Tools>System Monitor** and Dapper-Drake-6.06 **System>Administration>System Monitor** click the Resources tab and check CPU history to make sure it's at 100% all the time.  KDE and others I don't know where your GUI system monitor is.  For the console or terminal people type **"top"**.


[COLOR=blue]Step 8.[/COLOR]  Open your file browser also known as Nautilus and go to this location: [COLOR=green]**/home/username/opt/foldingathome**[/COLOR] or [COLOR=red]**/opt/foldingathome**[/COLOR] here you can check several things.  Such as to make sure one or more directory's were created.  There are a minimum of 2 directory's called **1** and** config** respectively.  Go into both and explore.  In my 1 directory I have 3 files of interest they are: [COLOR=green]**FAHlog.txt**, **MyFolding.html**,** unitinfo.txt**.[/COLOR]  Check them out as they all have very interesting info.  By the way the directorys that are numbers are the actual working clients.  Number 1 would be cpu 1 and 2 would the second cpu and so on.  So the config directory is just used for configuration, no actual work.

The HTML file will be the one you use the most from here on out as it will allow you to get to ** unitinfo.txt**  from within your web browser **and you can bookmark it.**

[COLOR=red]**Leave the other files and directories alone for best safety!**[/COLOR]


[COLOR=blue]Step 9.[/COLOR]  Give Folding@Home the best chance possible.
**Disable all screensavers.**

Cheers.

Thanks, I'll give it a try soon.

Let me know how it goes. Also you can choose from any number of teams out there if you decide to go that route not just team Ubuntu. I should have mentioned that even if you sign up with a team you still have individual statistics.

Thanks a lot for this. I had a friend that told me once about this, but I never installed before.

I followed your howto and everything went perfect. It's good to know my ubuntu is helping othes actively.

Thanks again.

henriquemaia, yes it is nice to know that this has a fairly direct impact on our lives as opposed to other projects that are big ifs. Not to say that others are not worthy but just that for some people a little bit more immediate benefit is important. Also projects like Folding@Home seem to go with the spirit of open source/free software. Anyway glad to hear every thing went well. I also cleaned up the howto a bit to make it easier for new users.

I would suggest you to give some spaces between lines on Step 6, to make it more readable. You could also add some bullets and bolds. Something like this:

Thanks henriquemaia.

The formatting ideas really make the howto look better. I gave you credit for the formatting suggestion.

Thanks for the tutorial. I installed Ubuntu last week after my Windows installation on my secondary (and largely unmonitored) PC became unstable *again*. Since then, I've been trying to figure out how to set this thing up with Folding. I just found this this morning, and now I'm back online with the second box.

• InNeedofHelp from team 36057

User D2X2903, glad everything went well with Folding@Home. Ubuntu forums are really the best place to find out how to setup up your Ubuntu box. There is just so much good info here.

oops, wrong thread....

*bump*

ndhskp: Great tut, but please note that this is a heavy tut to be doing for newbies and is great to do for those in advanced.

But for the newbies, could you please add the following below to your tut?

STEP: 1 Visit: http://folding.stanford.edu/download.html > STEP: 2 Select the 5.04beta version and "Save As". Then open your home directory and create a FAH folder and drag & drop the .exe in your FAH folder. > STEP: 3 Open a terminal and sudo chmod -x ./FAH504-Linux.exe > STEP: 5 ./FAH504-Linux.exe and then enter the following information as ndhskp has provided for you to do in setting up your user information.

This is for the .exe installation and works like a charm :)

How about adding in a tutorial about how to share Folding@Home so that users with EMIII running on Windows can monitor the progress?

Steve Myers said: ndhskp: "Great tut, but please note that this is a heavy tut to be doing for newbies and is great to do for those in advanced."

Actually it's very easy. All you have to do is cut and paste the code, you don't have to know really what's going on too much although knowing does help. If people want to follow your method that's great. So feel free to point them to your post or even write an alternative tutorial and send it in.

For drdeutsch: I have not a clue what your talking about.

I have been running folding@home for years, but now I'm trying to set it up on this ubuntu box. I have downloaded the executable, chmodded it, put in in the /opt/foldingathome/config directory. I have the two scripts, and have renamed and chmodded them and put them in /opt/foldingathome/.

However, when I run the install script (as sudo), it keeps saying that I don't have the folding executable. Obviously I do, so what's going on here?

However, when I run the install script (as sudo), it keeps saying that I don't have the folding executable. Obviously I do, so what's going on here? You say that you download the executable, what do you mean by that? The 2 install script files on the Ubuntu wiki for folding@home are all the files that you need. I am not sure about the exact process but I think that they download the executable for you. Also you seem to have created a /opt/foldingathome/config directory manually well you don't need to do that as that happens automatically.

Try deleting everything in the /opt/foldingathome directory and just leaving the /opt/foldingathome directory. Download the 2 scripts and proceed to copy and paste the code into your terminal from the howto. Remember the 2 script files are all you need don't download anything from the folding at home website.

Here's what happens:

$ sudo ./folding_install.sh

Creating directory structure...

It appears that you have not installed Folding@Home yet. Would you like me to download it for you? 1) yes 2) no #? yes

Please download the executable and save it to /opt/foldingathome/config. Then re-run this script. $

It just tells me to do it myself.

Make sure you are connected to the Internet when you are doing this.

Looks like this: It appears that you have not installed Folding@Home yet. Would you like me to download it for you? 1) yes 2) no #? 1

If this works great if not reply so I can continue to help you.

Also when you get to the question about running as daemon or manually and if you choose daemon use this command to start folding@home: username@ubuntu:/opt/foldingathome$ sudo /etc/init.d/foldingathome start

Ahh. Well, my embarrassment is overcome by my joy. Happily folding away. Thanks! :-D

Ahh. Well, my embarrassment is overcome by my joy. Happily folding away. Thanks! :-D What was it? Were you not connected to the Internet or was it the 1 as opposed to the yes.

Congratulations sir, most excellent! :-D

It was typing yes, over and over and over, instead of one. Duh.

It was typing yes, over and over and over, instead of one. Duh. I will contact the author of the scripts and suggest that he or she modify it so that it no longer matters whether one puts in a 1 or yes. That whole thing can be confusing sometimes. Anyway have fun.

Greetings,

I didn't follow the previously mentioned HOW-TO on getting F@H to work, I managed to do it on my own... but one small question.

if I want to get it start in a Daemon, how would I get that in there?

Thanks!

Well I don't know for sure. I know the Folding@home forums have a section devoted to linux and they talk about daemons there. However if you want you can just re-install folding@home using the same username and team numbers and any points you get from the new install will be added to any points that you already have. However if you do reinstall make sure your username and team numbers are exactly the same as before case sensitive.

If you don't want to re-install I can't really tell you anything as I originally followed the wiki myself. You would have to create a startup script that called the folding@home exucable and tell it to run as a daemon.

I would strongly recomend re-instaling and use the howto or wiki as a guide. If you really don't want to re-install then ask in this forum thread: Team Ubuntu Thread or at the folding@home forum here Folding@Home Forums

Good Luck sorry I could not be of more help. However if you need more info or wish more discussion then feel free to post some more.

I'm the author of the scripts. Please add a note to the HOWTO to PM me if there is a problem (but read on). Also, you don't need to leave your computer on 24/7 to make running F@H worthwhile, but it helps.

I found this by accident from ndhskp's signature. I'm glad people find the installer useful. I've read the thread and will correct the issues that people are having. It should be much better. Give me a day or two to update and test the installer before inundating me with bugs.

I'm up to 142825 points, try to beat me!

Hey great thanks for posting. I never had any problems because I just entered the numerical value "1" as opposed to yes. It can be confusing for users new to Linux to consider alternatives like "1" and so thats what was my reasoning to contact you.

I'll put up the note about PM and just say: Give the author a day or two to update and test the installer before inundating him with bugs. I'll wait till the new files are actually up first though.

What I am personally really looking forward to is the dedicated user and group mode. I don't know if you will have that in the next update or not but you got my support for it. Oh later this spring I plan on adding a couple of servers to my world so watch out here I come!

Worked like a charm, running it for the Ubuntu team as we speak

Execellent. Also feel free to post in the Team Ubuntu recruiting notice thread as that is were a lot of social talk happens for the team. Again congratulation.

lol i too join u drizek

just finished installing right now. most of the time running at 95% on my P4 3.2ghz :)

just finished installing right now. most of the time running at 95% on my P4 3.2ghz :)Super. And you have a nice Intel cpu with some muscle.

Thanks for the tut, I am a first time linux user and never coded a thing in my life so I know no command lines. After a couple of tries I got it to work and now I am folding away on my 7th machine (the others are some shape or form of windows)

You're folding on the windows machines too, right?

This is all quite impressive. I followed your instructions, and now my AMD 2GHz is folding away in the background. I can use the web and other things, and not even notice any slowdowns at all.

This is all quite impressive. I followed your instructions, and now my AMD 2GHz is folding away in the background. I can use the web and other things, and not even notice any slowdowns at all.Yeh the folding client is designed to only use cpu cycles that are unused, in other words idle cyles. So it should never interfere with any other activity.

This is a really helpful Howto. I have followed it again for another machine I set and all went well again. Now I have 3 CPUs working on this.

Thanks again.

Thanks again.Your welcome. :)

What would I have to change in the scripts to add flags? I'd like to add -forceasm -verbosity 9 .

Adding flags is the next step in the scripts. I'll work on it in the next few days. I have already added it, but have not tested or debugged yet. PM me if you want a preliminary version.

PMed you jpkotta

You're folding on the windows machines too, right? Yes I am folding with 8 processors right and hoping to add 3 in the next 2-3 weeks (waiting on a hub and a KVM switch). I am on the overclock.net team, I think we are in 60th place right now and I am 8th on the team. I have been folding for almost a year now and have over 200,000 points. My next project is a folding farm using one full pc as a server and the rest of the computers will not have video cards, or drives of any kind. Just a motherboard, processor, ram, nic, and PSU. I may even build a mount to put maybe 4 in one case.

hi, how can I active this program on start up ? I've installed it in my system (/opt/foldingathome), If my firestarter is active, Do i have to configure it for allowing F@H ? I can't find my "unitinfo.txt" at "/opt/foldingathome" anyone can help me ? thanks :)

Just a quick plug here for team Ubuntu. If you're folding, why not fold with the rest of us Ubuntu users? Just enter team number 45104.

hi, how can I active this program on start up ? I've installed it in my system (/opt/foldingathome), If my firestarter is active, Do i have to configure it for allowing F@H ? I can't find my "unitinfo.txt" at "/opt/foldingathome" anyone can help me ? thanks :)

It should automatically be set to start up on boot. To make sure, check that there is a file called /etc/rc2.d/S99foldingathome and a file called /etc/init.d/foldingathome. If you want to start it right now:

sudo /etc/init.d/foldingathome start

For the firewall, I don't use one. I got too frustrated getting everything to work with it. I'll probably set it up over spring break, and I'll make sure what settings are necessary. By default, the client uses port 8080. This can be changed in the advanced options, or you could set your firewall to open this port.

For your unitinfo.txt, it won't be in /opt/foldingathome. The way I have it set up is there is a configuration directory where no folding is ever done. The installer copies the config files from the config directory to each client directory (1, 2, ...; one for each CPU). So the actual folding takes place in /opt/foldingathome/{1,2,...}, and that is where your unitinfo.txt will be.

The new beta script seems to be working well. I've tried it with different and multiple flags with no problems.

If you want more information on what your client is doing, you can have a look at FahMon. There is no packaged version, but it is very easy to compile it on Breezy or Dapper as it depends on scons and wxwidgets 2.6.x which are available in the repos.

For myself I probably won't do it as thats a little too much work for me.

I'm creating a little python app for monitoring F@H on ubuntu. Setup is a breeze and there's no compiling. Should be ready fairly soon. I've already got a (pretty crappy) test version ready that works fine. But I'm reworking the guts completely, so that will take a little while.

I'll post back here when it's ready...

Quick question to all --

I've been folding for Team Ubuntu for a couple weeks. I've got FAH starting as a service when the computer starts. Everything seems to work well and I'm folding away, but I noticed in poking around my sytem that I have four instances of FAHCore_82.exe.

All of the processes seem dependent on process 8807 - /opt/foldingathome/1/FAH502-Linux.exe

Anyone have any ideas?

This is common behavior of the FAH client. Mine looks like that as well:

mwt@sequoia:~$ ps aux | grep FahCore 1001 8838 0.0 0.5 11896 5140 ? SN Mar11 0:00 ./FahCore_78.exe -dir work/ -suffix 02 -checkpoint 15 -lifeline 8797 -version 502 1001 8839 0.0 0.5 11896 5140 ?

Notice that on this page , almost at the bottom, it says that the FahCore starts up "several" processes when it runs as a service. No worries.

Good to know. Thanks! I read that page but missed that point.

Anyway, all seems to be well then!

Thanks!

The reason I noticed that particular section is that I want to implement stop | start | restart behavior with my FAH Monitor program. It doesn't look particularly easy, since you have to hunt down a number of running processes and kill them individually in a manner that is fairly unclean.

I'm looking for some good code sections in C++, Java, or Python that do something similar, if anyone knows of any.

Or are you talking about your programs threads. Not always but sometimes killing a parent kills the child threads I've noticed.

I have attached the log. The message is to long for display.

Hey anything to keep you folding!

Well, i haven't touched it between the installation and the noise. It used to switch on once in a while, for example when it was drawing a silly 3d screensaver. I think it has something to do with intensive tasks. I'm a complete n00b to linux, being used the no-noise Apple G5.

And it's for sure not dusty, i've put in extra ram one month ago and then ive blown 75% of all dust.

And it's for sure not dusty, i've put in extra ram one month ago and then ive blown 75% of all dust.Yes when the cpu is doing hard work it gets alot warmer and the cooling fans ramp up to keep it cool. You might check with your local computer store about getting a quieter fan, meaning quieter at top speed. But I understand if you don't want to buy a new fan and want to get rid of Folding@Home because fan noise is very irritating. I am hearing impaired and wear a hearing aid but I still can hear my fans and the difference is astounding when my computer is off.

Anyway I am still glad you have decided to use Ubuntu.

Nice! although it only has 2 Diggs at the time of this writing.

Anyone want to be the guinea pig for a very alpha folding@home monitor I wrote in Python? Will only work with a one fah setup.

Simple and effective - will show the percentage of the current work unit even when minimized. Nothing fancy. Not my problem if it sets your box on fire. ;)

I've been using it for weeks, and would now like some feedback from users.

I've been using it for weeks, and would now like some feedback from users.Okay I'll be your guinea pig, where do I get it or how.

I'll send it to you. - Should be in your inbox.

I'll send it to you. - Should be in your inbox.Okay, WelterPelter sent it to me. After checking it out for a few minutes I am impressed. Also it's very easy to set up and is self explanatory. For Folding@Home geeks it's just plain fun. I will now be using this on a regular basis.

C'mon everybody contact WelterPelter and ask for a copy and try it out.

Why don't you just attach it to your post?

Why don't you just attach it to your post?I will PM WelterPelter and ask him if I can put up the file. It's probably okay I just want to make sure.

See next post for downloadable application.

Thanks for the good review, ndhskp. :)

OK. Here's a version of the app, which is called "Protein Think", for folks to try out.

Please realize it may not work right. It's still in alpha.

I look forward to any feedback. Thanks.

Very cool, works great here.

I am hosting the program as well. But if WelterPelter finds a more permanent home (host) then I will take it down at that point.

Edit: took it off my site as it is now at Sourceforge.

Protein Think is now hosted at SourceForge. Get the alpha release here: https://sourceforge.net/projects/prothink/

Thanks ndhskp! You got me going on this thing.

Thanks ndhskp! You got me going on this thing.Very cool. Your on Sourceforge! And thank you for a cool program WelterPelter.

Everybody who wants to try the program get it at the Sourceforge page as that's where the current file will reside.

For anyone who's using Protein Think, there have been two updates to the alpha release. You won't have to setup again, just replace the files and restart.

CAUTION: if your hidden .stats directory is in your protein_think folder, make sure you don't erase that. However, if you do, just go through the setup again and you'll be fine.

These little fixes are coming fast and furious lately, so don't be afraid to check back at sourceforge every once in a while for a new version. :cool:

Yet another release that fixes some bugs, especially if your team name has spaces in it (unlike the TeamUbuntu name).

Since I'm updating this program a lot, you main want to select the "monitor" button on the download file page. That will automatically email you if there is a new file release.

I have a few questions.

If I install :fah_install-20060313.tar.gz

Will it create the directories needed? Or do I need to mkdir /home/folding_at_home or some such? move the tar.gz file to that newly named directory and "open" it once it is there?

Will it run at boot-up without the need for user intervention?

I can have the computer on 8 hours a day, but if I read the various posts here, if the screensaver is working, Folding is asleep? No work being done? Is there a way around this, other than turning the screensaver off? --A way around for someone who has been using Ubuntu/Linux since January 2006, that is?

Just follow the instructions. Untar the file, run the install script, and then you can safely delete the directory that got created by the tarball (fah_install).

It will automatically start at boot time if you install to the system. If you install as user it will restart every hour, unless it's already running.

If you run a screensaver that uses a lot of CPU cycles, then you will do less folding, and instead display pretty pictures. Personally, I choose a pretty screensaver that doesn't use a lot of CPU, "Intermomentary". But a screensaver won't turn FAH off, it just sucks away CPU cycles from it.

Why?

Try this:``` cd /home/put-your-username-here/Desktop

Don't literally type 'version'. If you're using the current one from the wiki,

tar zxvf fah_install-20060313.tar.gz

Also, as ndhskp said, you have to be in the directory that you saved the file in. If you lost it,

find ~ -name 'fah_install*.tar.gz'

I'll get it right, eventually:

mark@lexington:~$ tar zxvf /home/mark/fah_install-20060313.tar-2

gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error exit delayed from previous errors

mark@lexington:~$ tar zxvf fah_install-20060313.tar-2

gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error exit delayed from previous errors mark@lexington:~$

I deleted the downloaded .tar.gz and downloaded a fresh copy. Without the .tar-2. I moved the file to /home

mark@lexington:/home$ tar zxvf fah_install-20060613.tar.gz tar: fah_install-20060613.tar.gz: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: Child returned status 2 tar: Error exit delayed from previous errors

Twilight Zone, anyone?I am confused here. Are you sure you moved it to your home folder. You can keep it on your desktop if you want, it really does not make any difference where you place it. Open your file browser and go to your home folder to see if the file is there. Another thing is to put the file on your desktop and right click it and select extract here, but this is assuming your using the Gnome desktop.

Why is it getting renamed to *-2? Whatever. Just redownload the file. Anywhere. It doesn't matter. Just make sure that the filename is "fah_install-...". Then run the find command.

find ~ -name 'fah_install*'

It will tell you where the file is if it is anywhere in your home directory. So let's say it is in /home/mark/supersecretdir:

$ find ~ -name 'fah_install*'
/home/mark/supersecretdir/fah_install-20060313.tar.gz
$ cd ~/supersecretdir
$ tar zxvf fah_install-20060313.tar.gz

You shouldn't do things in /home, that's basically a system directory, a place for all users' home directories. You don't want to do things in /home anymore than you want to do things in /. Do your work in /home/username (aka $HOME, aka ~), or subdirectories of it.

We will get this thing installed.

We will get this thing installed.Actually by /home directory I meant /home/username. I guess I've been using Linux long enough that I had assumed that everbody would know what I was talking about, I sometimes forget that people will take things literally or that they are new users. Always much harder to get myself across using words. Jpkotta is right always use /home/username.

I will keep it in my mind for the future that not everyone will understand that when I say home I mean username home so from now on I will use /home/username. That can be confusing to others for sure. Thanks for catching that.

So Mark_in_Hollywood does this help you the distinction between /home and home/username.

Yes, distinction now understood. I have moved the fah...tar.gz to:

/home/mark

doing

ls

shows it residing there.

doing

mark@lexington:~$ sudo tar zxvf fah_install-20060613.tar.gz tar: fah_install-20060613.tar.gz: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: Child returned status 2 tar: Error exit delayed from previous errors

Anybody else got any ideas>

I'm baffled. If the file is in the directory, how can tar not find it? You don't need to use sudo to untar the file, but it should work anyway. I decided to install this on a school computer, just to see if there's some problem with the tarball on the wiki. It worked fine, but I found a bug (nothing major). Anyway, when I get home tonight, I'll fix the bug, upload the new version to the wiki, and make a zip file and post it here. Maybe a zip file will work better than a tarball, but I doubt it. Have you had trouble with other .tar.gz files?

Had any trouble with .tar.gz??

Hmmmm

Well, I'm quite embarassed to say that I'm not sure.

On one occasion I did a ./ for something. Mostly I've learned to let Synaptic do the work. Then Automatix and Update Manager.

I try to stay out of the operating system. This is my third time installing ubuntu, the two prior having blow up. As much as I want to Fold, I much more don't want to do a re-install. I'm using a 56K modem, the update/upgrade took over 7x24 hour day to download it all.

Please be patient. I've use Ubuntu since March of this year. Before that Fedora Core 4 since January 21st, 2006. Fedora blew up as I tried to update the OS. I got handed an Ubuntu CD and have never looked back.

I'm going to move that FAH file around and try to see what is "up".

Thanks for your timely, kindly on-going support.

Here's an updated zipfile.

So I saw the .zip file. Clicked it for downloading and "saved" it rather than having Firefox "open" it. It saved. Then I could do nothing with it. Called Nautilis and had the Archive Manager "open" it. A list of file appeared. The README had no instructions as to how to execute the installation. OK. I will try running the .sh in a terminal with ./

Wish me luck!!

Adding flags is the next step in the scripts. I'll work on it in the next few days. I have already added it, but have not tested or debugged yet. PM me if you want a preliminary version. Any update on this, jpkotta? I'd like to do the forceasm -verbosity 9 thing, also.

Also, the script still downloads version 5.02 of the client, while the most current release is 5.04.

PM on the way.

PM on the way.The latest script on the wiki and howto has full support for options. You should install the latest script. Also 5.04 is a beta client. The script only downloads the latest stable version. If you really want to download 5.04 then open Gedit or your favorite text editor and find all instances of 5.02 and replace them with 5.04 and save the file. If the editor ask to overwrite in the proccess of saving say yes.

Also, how do I know which version I have installed?

I think folding@home should be a package you can install via apt-get / synaptic. That would be a big boost for the project.

Stealing my avatar, eh? Or maybe I stole yours? Well, the more fractals, the better.

To run with the beta client, you have to edit exactly one line in the installer and exactly one line in the init script. Maybe I'll add a question in the installer that asks if you want the beta client or not. The magic line is the one with "executable=". I would recommend removing everything first before getting the beta client, so you have a clean install.

You can safely rerun the installer with the "update" option. It will not overwrite your current options files (unless you tell it to), nor the work queue. You can update if even while the client is running. Update only reinstalls the helper scripts, it does nothing with the client itself.

I don't think it's possible to make this a .deb file. You must download the client from Stanford's web site. You have to manually configure the client (unless you want to fold as Anonymous for Team Default). I don't think putting it in the repos makes it any easier to install. Anyone who wants to run it will search the forums or the wiki when they don't find it in the repos, and find the installer. And the main reason is that I'm lazy, and I don't want to learn how to make a .deb package (at least not right now). Someone else is welcome to, as long as the above problems are worked around.

OK, I am not too worried about the version of the executable. What about options like verbosity -9 and advmethods, etc?

From the README:

Configuration

There are two ways to configure the client. First, you can use the client's question/answer configuration. The reconfigure.sh script, located in the foldingathome directory, is the proper way to do this. Using it ensures that everything will be updated correctly.

The other route to configuration is by giving options to the client when starting it. The init script will get these options from two sources. The first is /etc/default/foldingathome. This is for system-wide options. All clients will look for it, even those installed to a user's $HOME directory. The other place is in the configuration directory, foldingathome/config. In here there should be an option file for each client. These per-client options will override the system-wide options.

This makes sense to me. If it is confusing to you, let me know so I can fix it.

Well did it work, I hope so.

Sadly, I report that death of my Folding at Home Project.

I tried the tar.gz, I tried the .zip and neither will write directories, etc. I'm more than baffled.

I haven't modified a thing of Ubuntu, without using Synaptic, Update Manager or Automatix. I haven't modified a .conf file anywhere. According to Update Manager, I have "everything" up-to-date.

So, for now, I give up and will revisit this issue once Dapper Drake is up and running.

NUTS!!!

From the README:

This makes sense to me. If it is confusing to you, let me know so I can fix it. jpkotta, I just ran reconfigure, and that's only for options *within* the program. I am talking about *command line arguments.* most notably -verbosity 9. How do I set those? Or are those in the realm of the second way?

edit: the second way seems to just allow editing of the client.cfg file, which again does not affect the arguments passed to the program, I don't believe

NUTS!!!Shoot, that always sucks when you run up against something like that. I know that I have been in that situation myself many times. Experiance Ubuntu some more and someday in the future just try agin. Dapper Drake 6.06 comes out in June so maybe sometime this fall. Good luck.

Look in those files for an example. I don't use those files myself, I used to until jpkotta pointed something out to me. Any way I can't remember if you edit the files then run the installer or edit the files in the folding dir, you'll have to ask jpkotta about that. Example of client.options file. Remember Linux command line arguments go here or system, of course.```

Folding@Home Linux client options.

This file contains per-client options. It will override options specified in

/etc/default/foldingathome, if it exists.

Use the CLIENT_OPTS variable to set any options that you want the client to

use.

Example: CLIENT_OPTS='-advmethods -forceasm'

Run the client executable with the help option (e.g. "FAH504-Linux.exe -help")

to learn what options are available.

Options specified here will override system-wide options.

To keep system-wide options, use CLIENT_OPTS="$CLIENT_OPTS -opt1 -opt2 ..."

Remember that double quotes are different than single quotes.

#CLIENT_OPTS=''

sudo ./folding_install.sh uninstall

OK, thanks. I will wait for Jonathan to post again before taking any action.

I did notice that I do not appear to have a /etc/default/foldingathome file on my system.

Thanks for all your help guys. I am used to doing this in WIndows with regedit, I like knowing what my performance fraction is.

Download the latest installer tarball from the wiki. Unpack and run the installer with the update option. You can edit the relevant files before or after you install. If you're installing to the system, then the relevant files will be /etc/default/foldingathome and /opt/foldingathome/config/client?.options. BTW, most config files for daemons ("services" in Windows) are in /etc/default (on Debian systems, anyway). I guess the nice thing about the registry is that everything is in one place. Of course, that's also the problem with it. I really wish distributions would standardize where files go.

OK, got it. I think I had a version from March. DLed the version from 4/21 and edited the systemwide options file. Thanks! (And sorry for being so dense--your help is really, REALLY appreciated).

Well, whatever I did, folding at home now no longer is automatically started at startup.

Wow.  I CANT RAED.

Edit:  I resarted after applying some updates and this time there was FAH at the top of my top display.

At this point I don't care what I did or anything, as long as this continues to be the case:

-folding starts automatically as a service at startup
-verbosity and forceasm arguments get passed to FAH every time it starts up.

Sorry if I am grumpy.  Have had a bad evenihg personally and venting it on the boards is not appropriate, but we all know that we're not robots.  Things get to us sometimes.  I probably need to watch some shocking videos of people getting their comeuppance.

I'm hoping someone here can help me out cause I can't seem to find what I'm looking for (either no one has asked or I've missed it) but I was wondering if there is anyway of checking the status of F@H on a machine running ubuntu with only the command line? I can check TOP and see it running, even after a reboot so I know I've set that up properly but will something like protein think work without a GUI or do I just need to take a look at the unitinfo.txt file to see how I'm doing?

I can check TOP and see it running, even after a reboot so I know I've set that up properly but will something like protein think work without a GUI or do I just need to take a look at the unitinfo.txt file to see how I'm doing?

Just take a look at the unitinfo.txt - that will tell you what's up.

Hello,

I set up folding following this howto.

I'm running dual opterons, and I'm currently folding as 'anaonymous' - can I set up the client1.options and client2.options (or /etc/default/foldingathome) to specify my username and team number?

Any help wuold be appreciated.

Thanks,

TFB

idiot.

completely missed the /1/client.cfg and /2/client.cfg.

question answered.

sorry

https://help.ubuntu.com/community/FoldingAtHome

Hi Everyone,

Fairly new to Linux and brand new to Ubuntu and having all kinds of trouble getting folding@home up & running on my Xubuntu installation.

I've followed the instructions very closely and can't get passed a "No such file or directory" error message.

I've used the install script AND the instructions on the folding@home site and no luck what so ever.

(Please note that I am folding on several other linux boxes withn distros from Fedora Core & Suse, along with a couple of OS X-PPC configurations, so I'm not entirely "wet behind the ears" but not competent enough to work this Xubuntu issue out by myself. Frankly, this has me completely baffled!).

Here's what happens when I run the install script:

[INDENT]./folding_install.sh install

Thanks so much for your help!

[SIZE="3"]Problem solved!![/SIZE]

The "No such file or directory" message was not referring to any of the folding@home related files but to a missing libc6-dev package and this will effect more than just your attempts to install folding@home. The "light went on" as I was trying to install Java and got the same "No such file or directory" message.

For those like me, not familiar with the libc6-dev package (and the libc6-dev-i386 which is needed for use with 64 bit systems) does the following:

[INDENT] libc6-dev: GNU C Library: Development Libraries and Header Files Contains the symlinks, headers, and object files needed to compile and link programs which use the standard C library.

libc6-dev-i386: GNU C Library: 32bit Development Libraries for amd64 Contains the symlinks and object files needed to compile and link programs which use the standard C library. This is the 32bit version of the library, meant for amd64 systems. [/INDENT]

It seems I needed to use Synaptic to install the libc6-dev-i386 package (I'm running a 64 bit system. The libc6-dev was selected automatically, must be a dependency?). I guess Xubuntu does not install the above packages during installation but Ubuntu does?

Now I'm folding as fast as the little rodent will run!

I'm just hoping that all the hair I pulled out will grow back.

Great community! I look forward to being a part of it all.

Thanks.

strange, i installed without sudo, and all went well until i tried to start it, which gives me: > ~/fah_install$ start-stop-daemon: Unable to open pidfile `/var/tmp/FAH502-Linux.exe-1.pid' for writing: Permission denied (Permission denied)

Please post the results of the following command:``` ls -ld /var/tmp

If that command doesn't work as a user, then run it with sudo.

Excellent Post told me exactly what i needed to do.

Thanx.

So what is the deal, is this going to clog up my system now? I thought this was just something that would use my cpu when the screensaver turned on?

Dare i ask if it would be possible to change the folder it installs to? I dual boot XP on here and would like the two OS's to have access to the same work files instead of doing their own thing.

I tried to figure things out on my own but this isn't exactly a simple batch file we have here. The other FAH install is on a mounted FAT32 drive. "/media/bigpart/fah"

You can't work cross platform in FAH. GO to the actual FAH forums if you want info on FAH on dual-boot systems. If you don't spend a significant amount of time on both OSs, you need to turn timeless WUs on at least the one you spend less time in.

Tobba25 said: So what is the deal, is this going to clog up my system now? I thought this was just something that would use my cpu when the screensaver turned on?

FAH runs all the time, not just when the screensaver runs. It runs at a very low priority, so you should never feel an impact (other than memory usage, but you can control that).

http://techreport.com/etc/2002q4/foldingimpact/index.x?pg=1

I was going to add this to the wiki page, but for some reason I can't edit anything in the wiki.

The Windows console client works in Wine, so you can run cross platform.

If you use the installer script from the wiki, you can just install as usual, and after installation:

• move /opt/foldingathome to whatever you want
• change the line "fah_dir=/opt/foldingathome" in the script /etc/init.d/foldingathome to point to whereever you moved it
• change the line that looks like "executable=FAH502-Linux.exe" to have the name of the windows client (or rename the windows client)
• change any lines that look like "--exec $client_dir/$executable" to "--exec wine $client_dir/$executable"

Disclaimer: I have no idea if this will actually work, but it should be at least a step in the right direction. You can always write your own init script too.

Also, I'd bet that the Linux client runs in Cygwin.

Okay, in need of a little help. I was able to set this up before but for some reason cannot get it to work now. I go thru the steps and extract the folder to home/sleepy127/folding and in that file is the fah install folder. I get to step 4 and I get a command not found error. I try to double click the folding install file and choose run in terminal and terminal pops up and closes immediately. If I choose to run it it does nothing. I can not figure out what I am doing wrong.

This is the last command that I tried. I modified the original command thinking that maybe it was not specific to my install and I received the same command not found reply. sudo ./folding/folding_install.sh install

The directory that gets created is fah_install, not folding. You can see what files (and directories) are in the current directory with the "ls" command (ls = LiSt). Look here for more than you ever wanted to know about the command line and Unix/Linux in general.

Has anyone tried this on edgy? If so did it work? Thanks

I'm always getting back here. As the winter approaches, I start using folding@home again, since during summer I can't leave the computers on all day. Once again, I just have to follow the howto to have things set up in a instant.

Thanks.

Does the script break on Edgy or is it only me? Since I dist-upgraded to Edgy I've been getting errors like these:

That's weird. Try changing the top line to ``` #!/bin/bash

Yep that fixed it. Thanks alot.

PS: why does it work in Dapper but not Edgy? Aren't sh and bash almost the same in syntax?

https://wiki.ubuntu.com/EdgyBetaAnnouncement

* New init system.

https://wiki.ubuntu.com/DashAsBinSh

Change the /bin/sh symlink on Ubuntu systems to point to the dash shell instead of the current bash shell.

That's probably it. I apparently didn't write the init script to be executable by a Bourne shell; I have some Bash assumptions.

I've updated the init script. I think it's not using any Bash extensions now. Also improved the "send" option. So give it a try and post back if there are any troubles. After I install a Edgy chroot and test it there, I'll update the version in the wiki.

robinl said: Yep that fixed it. Thanks alot.

PS: why does it work in Dapper but not Edgy? Aren't sh and bash almost the same in syntax?

Bash has a lot of extensions to sh. Any sh script will work in bash, but not necessarily the other way. I had assumed that by calling bash as /bin/sh, it would act like sh, but apparently, I was wrong.

I would appreciate Edgy users testing this (attachment in previous post). If a bunch of you test it, and PM me to say if it works, I'll update the wiki version immediately.

The new version still requires bash... If it's ran as it is it will output "fail" for everything (start, stop, restart etc.). Once changed to bash it runs fine.

Thanks for the feedback. I'll have to wait to do a real fix until next week then.

Thanks for the reply, I have been reading but I still cannot figure out why it is not installing. Here is what I get; sleepy127@ubuntu:~$ sudo ./folding_install.sh install sudo: ./folding_install.sh: command not found sleepy127@ubuntu:~$

Any word on the Edgy-compatitable version? Currently it doesn't auto start on boot and I have to manually start it.

robinl said: Any word on the Edgy-compatitable version? Currently it doesn't auto start on boot and I have to manually start it.

I downloaded the edgy beta live cd and booted it in VMWare. I installed folding at home. For some reason, it will not stop properly, although it starts ok (obviously, I have only tried doing things manually). I'm really confused as to why it is not stopping, it seems to be a problem with start-stop-daemon, not the script itself, but other init scripts use start-stop-daemon just fine. I haven't found any bug reports of a broken init script in edgy yet. I'm going to have time this weekend to work on it, so hopefully I'll be able to get *something* working.

Beta for edgy is up on wiki: https://help.ubuntu.com/community/FoldingAtHome

You can test it directly from the untarred directory:

cd
tar zxvf fah_install-...tar.gz
cd fah_install
sudo ./foldingathome stop

The problems I was having in testing seem to be related to the fact that I was using the Live CD. I don't have the space to do an Edgy installation, so I'm hoping for some good beta testers.

Currently the script works fine but doesn't auto start from /etc/init.d/ on boot.

robinl said: Currently the script works fine but doesn't auto start from /etc/init.d/ on boot.

OK, I freed up some space and installed Edgy into a VM. (The graphical installer from the Live CD is very slick, BTW.) I installed F@H and it started and stopped fine, as you said. Then I rebooted and it started at boot. Edgy has a new init system, but the interface to it should be the same, and since it worked for me, it seems like it is (I followed the Debian spec for init scripts when I wrote the installer and init script).

Try updating the client:

sudo ./install.sh update

I have have a server running Dapper 64bit version installed on an Intel 64bit Dual core CPU system with 4 Gig of memory, and I'm not able to run this script, it installed fine on my Desktop PC that is a Standard Pentium 4 CPU running Kubuntu 6.06.

The server would be an ideal candidate for running Folding@home for TeamUbuntu, since it is on 24/7 and has a load average of 0.09. So please help me get this running.

The script fails on running the FAH502-Linux.exe already when telling to push Q to exit the licence.

I get following error message: ####################################### Press 'q' to exit the license viewer. folding_install.sh: line 70: /opt/foldingathome/config/FAH502-Linux.exe: No such file or directory (END) #######################################

It also only detects 1 CPU.

I checked and the file FAH502-Linux is in the fodler where it is looking for it, and if I try to manually run it:

####################################### -bash: ./FAH502-Linux.exe: No such file or directory #######################################

I suspect that it is related to the fact that I'm running 64bit version, but if this is the case, is there a way to work around this?

Regards. Brian

ok, never mind, I found I just needed to install the ia32-libs package, and it worked.

However the scripts fails to detect the difference between having 2 CPU's because of dual core and having Hyperthreading.

So it only detects 1 CPU in my system even though there are actually 2 CPU cores.

So there are two cores, but they are each hyperthreaded? There are 4 logical processors, and 2 physical ones? Please post your /proc/cpuinfo file.

It only shows 2 CPU's.

Ahh, I see now. It looks like it has a processor in /proc/cpuinfo for each logical cpu, and each logical has 2 cores. I think this is completely braindead, but hopefully there is a good reason for it...

Check the wiki tomorrow for an update.

Yep, I'm getting exactly the same errors when I do the sudo /etc/init.d/foldingathome start command, it's getting very frustrating to the point I'm wondering if it is worth the hassle anymore..

I saw the post where it was said:

Top line refers to the first line of the foldingathome script. Any line that looks like ``` #!/path/to/program

sudo ./install.sh update

Why did I not just use bash in the first place? Because init scripts are not supposed to use it, they are supposed to work with sh.

It is worth the hassle. Your reports mean that I can fix the problems and others don't have to deal with them.

It's plausible, but I'd like to see some numbers. Try it with wine for a week and then with Linux for a week and see the difference. Ideally, each would work on the same WUs, but I don't think that's possible (you can't transfer WUs AFAIK and you certainly can't request them).

Yeah, you shouldn't have to add it to any of you're login stuff. That was the whole reason I made this. Well, let's see what we can do:

Make sure there is a link to /etc/init.d/foldingathome in /etc/rc2.d:

[jpkotta@euler ~](0)$ ls -l /etc/rc2.d/ | grep fold
lrwxrwxrwx 1 root root 23 2006-02-25 14:37 S99foldingathome -> ../init.d/foldingathome*

Make sure /etc/init.d/foldingathome is executable:

[jpkotta@euler ~](0)$ ls -l /etc/init.d/foldingathome 
-rwx------ 1 root root 4856 2006-10-21 16:31 /etc/init.d/foldingathome*

If that checks out, then change the "--quiet" in the start-stop-daemon parts of /etc/init.d/foldingathome to "--verbose". Then reboot and look for error messages on tty8 (ctrl-alt-F8).

Hint: you can copy and paste from the console by installing gpm (mouse driver for console) and selecting the text. Then you can log in on tty1 and start nano or another editor and paste with middle click.

nothing here, move along...

Really nice installer. I ran into one problem with the init.d script on edgy-eft (6.10). The script runs as bourne shell, but has some requirements on bash. The incrementor on the variable (++foo) and some of the double [[ on the test/if statements. When I changed the script to use bash, it all worked quite well.

Thanks. I'm well aware of the Bash-isms in the old init script. Visit the wiki for an updated version.

I can't get this to install in edgy.

I tried tar zxvf fah_install-20061021.tar.gz.tar and get

fah_install/

fah_install/foldingathome tar: fah_install/foldingathome: Cannot open: Permission denied tar: Skipping to next header fah_install/install.sh tar: fah_install/install.sh: Cannot open: Permission denied tar: Skipping to next header fah_install/README tar: fah_install/README: Cannot open: Permission denied tar: Skipping to next header fah_install/system.options tar: fah_install/system.options: Cannot open: Permission denied tar: Skipping to next header fah_install/reconfigure.sh tar: fah_install/reconfigure.sh: Cannot open: Permission denied tar: Skipping to next header fah_install/client.options tar: fah_install/client.options: Cannot open: Permission denied tar: Skipping to next header tar: fah_install: Cannot utime: Operation not permitted tar: Error exit delayed from previous errors

so then I tried the same command with sudo and get

fah_install/

Any clues?

I have no idea. I just tested it myself by downloading with another user on my machine and extracting. It went fine and the files were created as the other user, the default behavior for tar.

Do you already have that directory? Be very careful with this command!

rm -rf ./fah_install

Try using the --no-same-owner (and maybe --no-same-permissions) options to tar.

tar --no-same-owner zxvf fah_install-....tar.gz

Thanks for responding jpkotta, when I tried tar --no-same-owner zxvf fah_install-20061021.tar.gz.tar I got:

tar: You must specify one of the `-Acdtrux' options

Try tar --help' or tar --usage' for more information.

Oh, yeah, I don't think you can combine options after giving a long one. This is what sucks about Unix. There are a number of GUI archivers that may work for you too (I am not familiar with them); if you double click the tarball in Nautilus or another filemanager, it should open it up.

tar --no-same-owner -z -x -v -f fah...

ok, when I double click on the tar in nautilius, the unarchiver thing comes up, when I have it try to extract, it comes back with these errors.

tar: fah_install/foldingathome: Cannot utime: Operation not permitted

tar: fah_install/install.sh: Cannot utime: Operation not permitted tar: fah_install/README: Cannot utime: Operation not permitted tar: fah_install/system.options: Cannot utime: Operation not permitted tar: fah_install/reconfigure.sh: Cannot utime: Operation not permitted tar: fah_install/client.options: Cannot utime: Operation not permitted tar: fah_install: Cannot utime: Operation not permitted tar: fah_install: Cannot change mode to rwx------: Operation not permitted tar: Error exit delayed from previous errors

Yeah, something is borked with tar. Here is a zip, maybe that will work.

Thanks, just got home from work, trying it now... ;)

Ok, I got it all going right up to the point where it shows me the eula, I can't figure out how to accept it, it won't take any keys....

Press 'q'.

What is up with your machine? tar and less both don't work right? Man, I don't think I'm updating to edgy until I have some time to kill.

Hmmm, got past the eula (this time I saw the thing about hitting q (for a split second, then it was gone) it asked me if I wanted to set up a cron. I said yes. I tried using the command it gave to start, but nothing happened, so I rebooted, but the cron didn't start it either (no cpu usage to speak of and it's not listed in the processes.)

I don't know.....

Oh, it is running. Thanks jpkotta!

Doesn't matter, it's off and running now.

I've had Folding@Home on this PC for a while now, but it doesn't seem to have even started working. The log files are filled with the following:

[02:59:07] + Attempting to get work packet

[02:59:07] - Connecting to assignment server [02:59:08] - Successful: assigned to (x.x.x.x). [02:59:08] + News From Folding@Home: Welcome to Folding@Home [02:59:08] Loaded queue successfully. [02:59:09] + Could not connect to Work Server [02:59:09] - Error: Attempt #1 to get work failed, and no other work to do. Waiting before retry.

I'm not really sure what's going wrong here. My internet connection is fully working, but Folding@Home is never able to get any work. If I can fix this, I should be able to contribute, but I've no idea what would be causing this.

How long has it been since you got work? F@H appears to be able to connect to the servers (assignment server), it just seems that there is no work to do. See this post: http://ubuntuforums.org/showthread.php?p=1606734#post1606734 and the ones that follow.

I've had it for months now and, as far as I can tell, it's done absolutely no work at all in that time. I've changed "Request work units without deadlines" from 'yes' to 'no-prefs' in the hope that it will get my PC more work. It's on every day anyway (only shut down at night) so I can probably make deadlines without many problems.

Looks like they're out of deadlineless work units. http://forum.folding-community.org/portal.php?topic_id=16235

Does the installation script (instead of the .exe) ask the configuration question about deadlines? If yes, could/should it be removed for now?

The installer I wrote simply runs the client with the -configonly option during installation. I can't change what questions it asks, and I'm not going to have it not run -configonly, because that's about the only way to set user name and team number. The default is no-pref anyway.

Well now that I've removed the requirement for deadlines, my PC has got a work unit and is processing it. If I knew how lax the deadlines were going to be, I would've done this ages ago. This work unit has to be completed by February 25th, but my PC has done 5% of it in just 7 hours!

It should also be noted that I'm looking to get myself a Core 2 Extreme sometime next year (likely a quad-core one), which will blitz this old work horse.

this is what happens when i try to start mine does anyone know whats wrong?

That is not an error, it is a message. It is normal.

So I figured I'll give this software a shot and installed it using the beta version (fah_install-20061021.tar.gz, have edgy installed) and seems to have worked fine except for one thing. It says it could only find 1 cpu even though I have two. Anyone know how I could change that? My system is currently only running at 50% and would like to make use of both my processors. thanks a bunch.

It seems like there is no good way to determine if you have physical processors (dual core) or logical processors (hyperthreaded). Read the wiki for why the difference is important. I will update the installer this weekend so that you can choose how many.

It wont work though

Yes, that is an error (however "-configonly flag given, so exiting. Terminated" is normal). Someone else notified me of the error in reconfigure. There will be fixes this weekend. It might work if you change the first line of reconfigure to "#!/bin/bash".

New installer scripts available. I think I fixed the bugs. I have an Edgy VM that I tested in, and it works perfectly there. If you have already installed, then you should only have to do an update.

thanks for the update, Im folding for teamubuntu now!

Hi there

Not sure if this is the right thread but I setup folding@home a few months ago using this guide and everything is working nicely, Thanks for the great guide :) however I am planning on upgrading my computer with a new hard drive and would like to know how I can backup my folding@home files.

Which files do I need to copy so I can reinstate them later? I can't seem to just copy and paste the folding@home folder so is there a command I can use to make a backup of the files? Sorry for the stupid questions but any suggestions/advice will be much appreciated.

Cheers

There is a problem with how the install script counts my Turion64 X2 CPUs. It counts it as just one CPU when it is really two. This stems from the check for the "ht" flag in /proc/cpuinfo. This flag does appear in AMD X2 chips and does not indicate HyperThreading capability. To quote some info I found on the net

"...It denotes that fact that the processor is capable of exposing more than one logical CPU..."

Now I don't know if this is really true but when checking /proc/cpuinfo I do see the ht flag and my system does not have HT. There needs to be a better way to check for HT now that modern AMD dual core CPUs contain this flag. I fixed (dirty hacked) this problem by just commenting out the last two lines of the num_cpu check which is safe for me as I know I have two CPUs and no HT.

If you used fah_install, you do this:

sudo tar zcvf fahbck.tar.gz /opt/foldingathome /etc/default/foldingathome

That should save all of your work and settings.

To restore, ``` cd / ; sudo tar zxvf fahbck.tar.gz

After restoring, use the fah_install script with the update option.  This will not overwrite your work or settings, and will set up everything to start at boot time again.

I can't find a good way to get CPU detection to work right. The latest installer has some improvements and the ability to manually set the number of CPUs.

Hi all,

I wrote a simple Folding@Gnome applet to graphically monitor your folding progress and set preferences in. For those interested, you can find more info on my website.

Please report any strange behaviour! The applet works fine here, but is still in "testing" until it works fine for more than one person of course!

Does anyone know of any way to set F@H up so that it still runs as root but have the work unit stored in a folder in /home?

Also is it possible to tell F@H to finish the work unit it is on, send it and then exit?

Thanks in advance

Why do you want it to run as root? It really shouldn't. Try hacking my installer, it should only be necessary to change the "fah_dir" variable in a few places to make it use the folder of your choice. As for running as root, I went through a lot of trouble to make sure it *doesn't* need to run as root. You would need to hack the foldingathome init script and the reconfigure script. The really quick and dirty way is to use su (read the man page).

You can give it a command line option to finish the current unit and send and quit: '-oneunit'. If using my installer, you would this option to the /etc/default/foldingathome file and restart.

Thanks for the reply

Perhaps I don't mean as root. I installed it using the script in the wiki. It installed to /opt but I would like to wipe my / partition. /home is on a separate partition so if I could somehow copy it there that would mean I could keep my current work unit. I'll have a look at the scripts and stuff and see how I get on.

That's easy. It's a good idea to shutdown the client before backing up.

Edit: Added FAQ to wiki page: https://help.ubuntu.com/community/FoldingAtHome#head-774c7065f707a8798b15820b9ff824f3e1fa34bd

hey fellow folders! i recently installed the fah client on my laptop, along with some nice cpulimiting. i posted a pretty thorough howto about it on my ubuntu chronicles page here: http://pykeylogger.sourceforge.net/wiki/index.php/Ubuntu:Chronicles#Folding.40Home_.5BFAH.5D_on_a_Laptop in case anyone is interested. :)

i have it running at 50% cpu load - that keeps the cpu nice and cool (otherwise, fan keeps revving up if i just let it run at 100% idle load), so that should prevent any premature death due to folding. ;)

hope this comes in handy for some of you.

Hey thanks it WAS useful. I kept trying to install the program for the past couple of hours with scripts that didn't seem to be up to date and when I read your description saying "it simply boils down to" I was finally able to make it run.

So thank you !

Next time I'll have to make it run in the background. But enough for today :)

Bragador:

Are those scripts the ones from the wiki? Can you describe what went wrong?

jpkotta said: Bragador:

Are those scripts the ones from the wiki? Can you describe what went wrong?

What I meant was that I tried to use both fah_install and finstall to install folding@home and yes, both didn't work.

The ubuntu one went wrong when I had to enter the install command:

sudo ./folding_install.sh install

The command didn't exist apparently. I managed to install it by changing the commands to something else so the wiki wasn't up to date it seems. After some tinkering I made it but I wasn't sure how the files were installed so I kind of panicked and managed to uninstall everything. So yeah in the end I think I did it but since I didn't understand what the script was doing I didn't like it.

As for the finstall I received a 404 not found when I tried to get it.

What I finally did was to download f@h manually and start it from its own folder with the terminal. I wish I could make it run in the background though but it's not too much of a problem for now. At least I know where all the files are.

Bragador:

You are absolutely right that the wiki was out of date. Thanks for pointing that out.

The README mentions which files and directories are created during installation.

Well I'm glad I helped the community then :D

Also you are right about the README. I guess I was expecting to find my folder organized like in windows and that's why I ended up not using the script in the end.

I've just found out you are the coder for the script so kudos to you !

Hi, I'm a total noob to Linux, but I managed to follow the instructions on installing, but I can't get it to run, I get this in Terminal after entering sudo /etc/init.d/foldingathome start :

What version of Ubuntu you're on? (system > about Ubuntu)

I don't know what the problem is but somebody else will. Welcome to Ubuntu and welcome to the Ubuntu folding team!

Thanks for the welcome. I'm on Ubuntu 6.10 Edgy Eft

As I'm reading the instructions again, they state that the script resides in

/etc/init.d/foldingathome start

but when I actually navigate to /etc/ there is no init.d at all...:confused:

This is a bug that was caused by the switch from bash to dash in Edgy. The newest scripts in the wiki have this fixed. Read the wiki for quick instructions for installing/updating the scripts. Link: https://help.ubuntu.com/community/FoldingAtHome Great! I followed the wiki and got it running. I checked the system monitor and the CPU usage is at 95-100%, which I assume it's working.

Just a quick question, if I need to stop the client for some reason, how do I go about it. I was reading the wiki and it mentioned finstall, is that like a script just to start/stop/status the client?

I assume that checking the "status" would let me know the stats on what's going on?

You control it with the init script. All init scripts are supposed to have start, stop, and restart commands, and this one is no exception. Many have a status command too, and for this one, status will print out the end of the log file for each client. You may rather simply look at the log file manually because that way you don't have to use sudo. I have the following aliases in my ~/.bashrc:

alias fah_log='less /opt/foldingathome/1/FAHlog.txt'
alias fah_tail='tail -f /opt/foldingathome/1/FAHlog.txt'

There are also little applets (e.g. for gdesklets, gkrellm, etc.) that provide a GUI to monitor the client.

finstall is another script that basically does the same thing as this one (which I'm unimaginatively calling fah_install). Of course, I think mine is better.

Did you guys understand what caused that problem? (I didn't) If you did, it's cool, no need to explain really. I was just wondering how this problem was created and if some process should be improved to avoid this in the future. o_O

I know, I'm a funnyguy.

The problem is that /bin/sh used to point to /bin/bash, but in Edgy it points to /bin/dash. dash only understands Bourne shell, while bash understands Bash language, which is a superset of Bourne shell (hence Bourne Again SHell). I had bash-isms in the scripts, which dash doesn't understand.

The way to prevent it is to RTFM. I should have RTFMed the fact that bash still acts like bash when it is called as /bin/sh, and that those statements don't work in Bourne shell. People who are running Edgy and have the problem at this point (not the ones that first reported it, obviously) should RTFM (i.e. the wiki or this thread), because it is a known problem with a easy fix. Don't take the above statements as being harsh, they are simply the best way I can see to prevent problems of this type. The "F" in RTFM means the same thing as the "F" in FVWM.

You guys are gonna hate me, another n00bish question I bet....

I'm trying to get stats on what my computer is actually doing, I've read that the unitinfo.txt file shows this info and that it should be located in the opt/foldingathome/ folder, but the only file there is: MyFolding.html and it tries to pull up /opt/foldingathome/1/unitinfo.txt but firefox says it doesn't exist.

Are you starting your Folding@Home from another directory than where it is actually located? Folding@Home will drop those files in the directory where you started running Folding@Home

Depends how much you're going to fold! :lol: (just kidden)

Do a sudo updatedb and then locate unitinfo.txt

That will find probably find it. (on linux filesystems by default)

xyrcncp:

Post the output of this command:

locate unitinfo.txt

Edit: I'm sloooow.

edit: nevermind ;p

I can't find unitinfo.txt.

locate unitinfo.txt just drops to the next line....

Did you update the database first? Do you have non Linux native partitions? (vfat or ntfs)

By update the database I assume you mean: sudo updatedb.

Yes, I did that. I do have a couple of fat32 partitions. Do I need to do something else to see what it's doing?

Yes, that's what I meant. It doesn't index non-Linux partitions by default. If the file's on a vfat partition you need to edit /etc/updatedb.conf and remove vfat from prunefs. Then update and then locate.

Hmmm, I don't belive that it is on a fat partition, and the file /etc/updatedb.conf doesn't contain an instance of vfat, or even just fat (I searched for both).

How would I be able to automatically run it when my screensaver begins(I use a blank screensaver)?

Ok, so after redoing my drives and reinstalling everything I can finally see my unitinfo.txt...yay! However, as far as I can tell I have sent in 2 work units and my personal statistics page never updates. anyone have a clue why?

If you mean the MyFolding.html page, it wont; it contains static information. The link on that page, unitinfo.txt, will be the one that updates. If you mean the Stanford pages, I believe they take a little while to update if you're a new user.

Jpkotta, thanks for the script and howto. I do have an issue with the battery/ac script. It doesn't kill or restart FAH. I've tried chmod +x on the "fah" script under both directories but that doesn't fix it. Is anyone else using it and if so, does it work for you?

Yeah, it is the stanford page I am talking about. While I'm not a new user, it has been a while since I turned in a work unit (the last one before the current crop was 2006-07-29 14:15:52), so maybe that's like being a new user again.

Which version of Ubuntu are you using? Hint:``` cat /etc/lsb-release

It works for me obviously, with both Dapper and Breezy.  I do Edgy testing in VMware, and I don't know how to simulate ac/battery events.  Note that it may take a while before it actually shuts down/starts up.  Mine always works in under a minute.

Speaking of testing, has anyone tried this (the installer/init scripts) under Feisty?

I'm using Edgy. Maybe I'm not waiting long enough or maybe it has something to do with the switch from bash>dash (similar to what you went through with the install script I believe). 

Minutes later...

Ok, I tried adding #! /bin/sh to the "fah" script and it did nothing. I waited even longer (about 3 minutes) and it didn't kill the process.

So, both scripts look like the following and are executable, but do not work?? They do what they should when manually executed (sudo ./fah). They are also identical (in re: permissions and +x) to the only other file in ac.d and battery.d, named "15-anacron.d". In case you're wondering, my laptop is a Compaq Presario 2100 and is able to detect when I plug and unplug the power adapter. 

#! /bin/sh /etc/init.d/foldingathome stop >/dev/null

#! /bin/sh /etc/init.d/foldingathome start >/dev/null

Hey moz_21, just curious, how long do you think it will take?

Apparently, the scripts in /etc/acpi/{battery.d,ac.d} must end with ".sh". I don't think they need to be executable or need a shebang on the first line. Wiki has been updated.

DarkDancer said: Hey moz_21, just curious, how long do you think it will take?

As long as it takes when running the script manually. ;)

Hah, how weird. That did the trick. I was going to try that but I guess I forgot. Now it runs just like when Window$ was on it (and everyone knows how)! Thanks!

I'm afraid I don't understand the answer to the question.... #-o

DarkDancer said: I'm afraid I don't understand the answer to the question.... #-o

It should take just as long as when manually starting or stopping it, via either /etc/init.d/foldingathome stop (or start) or when running the same thing via the fah.sh (note the .sh to make it work) located in the /etc/acpi/battery.d or /etc/acpi/ac.d.

It took about a minute to shutdown the service and it starts back up within a few seconds.

Oh, now I understand why I didn't get the answer, you're answering a different question... ;)

My question was about how quickly you thought the Stanford page would update me, it hasn't yet and I just wanted to make sure I wasn't crunching to no purpose... ;)

Doh! I thought you were being a smart*** when you first asked it... Sorry about that.

Well first off, make sure you're looking at the right stats page. Be aware that it is case sensitive. If I remember right there are some characters you can't have in your username or it will fold anonymously. Otherwise it should update pretty quickly I'd imagine. To be honest, I've been folding since 2001 or so; i really don't remember how long it took. Just double check everything over.

Fyi, another good stats page: http://folding.extremeoverclocking.com.

Extremeoverclocking has all the old info for me (from 2006) but none of the mew that I have turned in, very much like stanford.....

The Stanford page I go to is the one from "My Folding Page" which I would have to think would be the right one. If something doesn't go right, is there an error log or something that is created?

Wow, moz, you have almost a million points. Way to go! Too bad you're not folding for TeamUbuntu, we could use more.

As it should; it uses the stanford page for it's own updates. I'd have to say the client.cfg file is corrupted for some reason. You might want to stop the service, delete the client.cfg file, and then run the reconfigure script (/opt/foldingathome/reconfigure). :edit: I just read that DST is screwing up the updates for some people so that could be the case also.

Hehe, guess I just needed to wait a litttle longer, it updated... ;)

Used the how to and everything working well. Also downloaded protein think. However I have a few questions to ask. I have a Intel 4 3.0GHz HT processor, however in the System Monitor the Fahcore runs at @50%, while in the HTOP or TOP CLI the Fahcore runs at @100%. Is that anything to do with HT processors which are virtually seen by system monitor as 2 processors. Will increasing the number of processors to 2 during config increase the processor load to 100%?

Yes but I believe the efficiency goes down. I'm not sure what the official word is although you may find this to be helpful:

http://folding.stanford.edu/FAQ-settings.html

Computers with multiple CPUs (SMP) are supported under FAH in two ways. For Intel-based Macs and x86 PC's running linux, there is a special SMP client. For other machines, one can use multiple processors by running multiple clients (one for each CPU). This is clearly non-ideal and better support is under development. There are certain caveats of using SMP boxes with special flags. Do not run multiple clients with each set to the most aggressive settings (bigWU + adv), as this can overwhelm most computers. Instead, we suggest bigWU+adv on one client and the default settings on the other(s). In situations where reliability, stability, and/or responsiveness a premium, we suggest either all clients with the default settings or just one client with the big WU enabled.

Thanks for the prompt reply moz_21, that really cleared up things. Now for two more queries. I see that the folding@home has created a user of the name foldingathome, with home directory in /opt/foldingathome, is it normal? Now the second question, when I run foldingathome my cpu is 50 - 100% occupied, and the temperature stays fairly high about 75 degrees celcius, it may be due to high ambient of our region (around 30), now I have seen my processor specs and 75 deg is at the higher band, but is running continuously at high temp ok? Thanks in advance.

The dedicated user is normal and a security feature. Running too hot can damage the chip and might shorter it's lifespan. I wouldn't suggest doing it. I'd constantly keep below 70. That's a pretty high temp but so is the ambient too. Have you got a proper fan and a well placed heatsink with the correct amount of heat conductive paste?

Thanks Glotz, well as a first step I removed the processor heat sink assembly and thoroughly cleaned it, (it was full of dust), the result - temperature within 70 degree, (@68 ), now as a next step I have to put thermal pad/glue, I'am sure that will help.

That P4 you have is a hot runner anyhow. Keep the fan clean and you'll be just fine. It should throttle or shut down if it ever gets waaayy to hot but that would probably only happen if the fan dies.

mahiyar, all of your questions are answered on our wiki: https://help.ubuntu.com/community/FoldingAtHome.

The HT question has it's own section. Yes, you can run two clients and get your CPU meter to 100%, but since you're already worried about thermal issues, it's probably not a good idea. There is a program that limits the CPU usage of a given program if you're still worried about temperature (link in the wiki).

Hello everyone,

Great info on setting up the folding client. However, i have 2 issues. I have a machine running windows vista and one running Kubuntu edgy behind an ipcop firewall. The first problem i'm having is that in Kubuntu, i've had the client running for about 2 days now and still no unitinfo.txt file. sudo updatedb and locate turn up nothing. I've verified the client is properly running with top and ksysguard. The other issue i'm having is that my windows machine is failing to send work units back, i get "could not connect work server (results)". I've port-forwarded port 8080, and made sure the windows firewall wasn't interfereing, but still get the same error. Any ideas anyone? I'd really like to donate!

Thanks in advance!

EDIT: I finally have a unitinfo.txt file, and i found that IE7 was the problem. I have no idea what took so long, but I'm happily crunching and hopefully sending units in now.

Script works grand on Debian :)

rowanparker said: Script works grand on Debian :)

Excellent! I didn't waste my time reading the Debian docs (they were interesting anyway).

I've been running fah for a couple of months now, and it is working.

I'm not sure I have it configured correctly though for my AMD 64 X2 processor. When Fah is running, it never reaches more than 50% utilization, which is fine. However, my understanding is that it should scale down as more processor is needed. I never see fah go below 45% utilization, even when another process is dragging the system to its knees.

Is this normal behavior for fah? Its running with nice set at 19.

muguwmp67:

It sounds like you're only running one core. You may want to try the SMP client or if you used fah_install from the first post in this thread, then you should set it to run 2 clients. You want to run one UP client per processor, or one SMP client for all processors.

I have decided to build a machine as soon as Intel chips drop in price, which should be around April 22. Then I will be able to test my scripts with SMP clients and add an option for installing them. Right now, you can probably just change the name of the executable in install.sh. Has anyone tried this?

It is. You've set it up to use one core. Anything that isn't multi-threaded will show as 50% usage when it's going full bore. Since the majority of applications are still single-threaded you are able to run FAH at maximum usage on one core and just the OS and apps on the other.

That sounds exactly right. If you were running a single core (or if you run a multi-threaded application) it would scale back. FAH is very unobtrusive on every computer I've had it on. The big thing is ram. If you are running big-packets or the beta SMP client I recommend 1GB of ram (unless it's a dedicated folder; you can get away with half of that if you don't need to load a GUI).

I was thinking the same thing about the script but I don't have an x86-64 capable dually running Linux. If/when the 32bit linux SMP client comes out, I'll give it a try but until then I can't say I'm much help.

Thanks for the explanation. I haven't noticed any performance problems while running fah, but was curious as to why it didn't look like it was giving away cycles to other apps. This also explains why the super_pi script comes up with roughly the same result whether fah is running or not.

hi everyone I started running F@H a few weeks ago; installed it using the fah_install script. Everything was running smoothly (after a few minor tweaks). Recently I started having problem uploading a couple of WUs, but found out it was server problem at Stanford side; so that should be resolved once the data server is fixed.

Anyway, on to the reason I am posting here. While investigating the problem above, I found out that I was running FAH502-Linux.exe. I recalled during the installation process this application was automatically downloaded by the fah_install script. However, I also noticed the latest version at F@H website is FAH504-Linux.exe.

Questions:

1. Is it ok to continue running version 502?
2. How do I go about updating to version 504?
3. If I update, will my existing completed WU be retained (or should I wait until successful upload before updating to version 504)?

Thanks for all help/feedback. :D

Maybe the best thing you can do if you want to update is to copy the whole 5.02 folder and replace the 5.02 executable with a 5.04 executable. This way you can easily test if 5.04 continues working with your 5.02 WU's. If not (and your WU's are destroyed or something) )you still have the GOOD directory with a 5.02 executable and the original WU's. My quess is that 5.04 will continue working on the WU's fine, but this is a way to try.

Hey, thanks. Sound like a good workaround. I followed it, and it looks like the my finished WUs are still ok.

The only minor issue I noticed is that executable filename is coded inside the fah_install script, and i don't know enough about the script to be able to change it to "FAH504-Linux.exe". Instead I have renamed the filename "FAH504-Linux.exe" to "FAH502-Linux.exe".

Haha, great workaround as well :D

If you want some sort of monitoring applet for your folding process, there's one on my website.

ruudiculus said: Haha, great workaround as well :D

If you want some sort of monitoring applet for your folding process, there's one on my website. I recently have a conversation with you in the applet thread; reported a problem getting the applet added to the gnome panel. :D Haven't got around to investigation more about it. Instead, I have worked out another way to monitor using conky.

I think it should be set up but I don't think it is running

when I enter "start" in /opt/foldingathome/ I get error msg

start: missing job name

Try `start --help' for more information.

So how do I get a "job name"

Also I'm running the script from the wiki after uninstalling the script in this thread

It looks like the client has stopped right there, at step 0. If I check status it says that the client is running. Has it stopped or just that it does not update until it has completed the current task?

That's normal.  By default, every 15 minutes, it will save the computation to disk, and you should see a new message.

i used the fah_install script and it worked great, then i had to re-install Ubuntu and so i used it again and copied my old directory but now it runs and works for a while i come back and it's no longer running. anyone else having similar issues? P.S i'm running fiesty

I've had trouble in the past using restored backups. It's not guaranteed to work. The fact that it runs for a while suggests you did everything correctly, and the client is having trouble in spite of it.

do you have any suggestions on how to fix it? uninstall/reinstall, remove work folder etc?

Maybe I'm forgetting something. Can you say whether or not this command returns anything?

grep foldingathome /etc/passwd

If it doesn't return anything, then it isn't installed completely, and you should keep your backup, uninstall, reinstall, then replace the installation with the backup (the installer does more than simply copy files).

[FONT=monospace]foldingathome:x:1001:1001::/opt/foldingathome:/bin/false

Like i said, it runs for awhile (15 min?) then quits. possibly when trying to write to the log. (just realised that it's possibly related to a problem i've been having with gedit... investigating now... will post my findings within the half-Hr)

[/FONT]

well it's been nearly an HR and still nothing (it's still working) but it hasnt moved a percent yet, so i assume it's running properly.

nope, it quit later, i ran it from the terminal today and it's gotten through about 6-7 percent, so once it finishes i'm going to un/re-install

I was thinking that maybe it didn't have the special f@h user created, but it does. Your plan is what I would do.

yep, it finished so i re-installed and i caught it at the right time because the work server was down. so it now works fine!

Hi, Sorry if this is the worng place, I can't find an answer on the Forum.

How do I move a WU at 23% from one computer to another. An old P450 box is working on a big WU and and has crashed a few times. I want to put it on a faster cumputer so it will finish before the deadline.

I copied the Folding folder and all it sub folder to the faster box but it does not restart the old WU from the saved piont. It fails the run any WUs. With new FAH504 download and install it retrieves a new WU.

I must be missing a setting in the -config after changing computers.

I a new to Ubuntu and Folding@Home.

Thanks

Is the slow computer a Windows machine? You need to jump through some hoops to move from Windows to Linux. Look at the Sneakernetting link on the F@H wiki page (see my sig). That will tell you 90% of what you need to do to move WUs from Windows to Linux (the other 10% is installing Wine).

Anything you set with -config is stored in client.cfg, so all settings should be copied.

Both the old and new computers are setup with Ubuntu 7.04.

I looked again at the Sneaker netting page. I think I did what the page said about moving WUs between computers with the same OS. I know nothing about a Ubuntu Registry (or if it has one). Do I need to copy some thing else to the new computer to get it to recognize the old WU? I did move the entire FOLDING directory/folder to the new computer.

I want to move the old WU to a different computer and continue folding that WU on the new computer that is network and internet connected.

I just can’t get the faster computer to work the old computers WU. It is folding a different WU as we speak without any problems.

The old computers WU is: p4308_dpdp-ii I think it’s a Beta WU, that may have something to do with the problem.

I will keep trying.

Thanks

There is no Ubuntu registry (thank goodness). You would have used the Wine registry if the slow computer was running Windows.

All I can say is that F@H was not designed to move WUs around, so there is probably some hidden undocumented thing that is causing the move to fail. Maybe check out the semi-official F@H forums http://forum.folding-community.org/. I have moved WUs between Windows and Linux, but it was not easy, and the computers I was using were very similar hardware-wise.

I'm getting the following errors when I follow the howto:

ub-desktop:~$ sudo /etc/init.d/foldingathome start

Ugh. You probably got this from the forum thread. I hate the fact that only one person can edit a post. Wikis are better for this kind of thing. I'll talk to an admin about removing the old version of the script.

Use the latest version from the wiki (link in my sig).

I installed Folding@Home earlier today and have some questions:

-If I close the terminal window, does that close f@h, or will f@h run in the background? Is there a specific command for exiting f@h? (I shut my computer down at night, and I don't want to screw up f@h by exiting the program incorrectly)

-If closing the terminal window does close f@h, is there anyway to prevent this? (should I run f@h in the background? As you can probably guess, I'm a linux newbie.) I'd rather not have to keep a terminal window minimized all the time.

-Why doesn't my username show up on the stat list on the website? (I can't check now because their server is down, but earlier it wasn't listed.) Is it because I haven't finished folding my first protein yet?

-I'd like to join Team Ubuntu. I do this by going into config and setting my team to 45104, right? Can I do this while F@H is already running?

Thanks.

that depends on what command you use to start the fah client...

-If closing the terminal window does close f@h, is there anyway to prevent this? (should I run f@h in the background? As you can probably guess, I'm a linux newbie.) I'd rather not have to keep a terminal window minimized all the time.

if you add ' &' to the start command, that will put it in the background, and you can safely close the terminal. if you want to later kill the process, just find it in the process list (in system monitor), and kill it.

-Why doesn't my username show up on the stat list on the website? (I can't check now because their server is down, but earlier it wasn't listed.) Is it because I haven't finished folding my first protein yet?

yes, your username won't show up until you submit your first completed work unit (and there will be some delay after that, since that list isn't updated real time.

-I'd like to join Team Ubuntu. I do this by going into config and setting my team to 45104, right? Can I do this while F@H is already running?

Thanks.

you have to restart the fah client in order for the changes to take effect.

i think that takes care of all your questions. ;)

Thanks. One more question: when I close the program, it saves the progress it's made so far, right? I'm not going to lose the data because it didn't finish folding the protein?

yes, it saves progress periodically, and fairly frequently. so you won't lose anything to speak of. :)

I tried running it in the background, closing the terminal window, opening a new terminal window and typing "ps", but the only processes listed were bash and ps. So I tried running it regularly, opening a new window (while it was running in the other window) and typing "ps", and it still wasn't listed.:confused: Any idea what I'm doing wrong?

try:

ps -e

The -e parameter tell ps to show every process. Without it, you only see processes related to your logged-in account. (Folding runs as a root process, I believe.)

Depends how you installed it. I used the script provided with sudo and then it's running on it's on 'foldingathome' account.

ok, it shows up if I use ps -e, but if I close the terminal window it disappears from ps -e, even though I was running it as ./FAH504-Linux.exe&

GreenGirl said: ok, it shows up if I use ps -e, but if I close the terminal window it disappears from ps -e, even though I was running it as ./FAH504-Linux.exe&

Closing the terminal will stop the process. The wiki has an script to setup FAH as a service which resolves this issue.

ok, thanks. :)

I installed finstall and rebooted my computer. It looks like fah now starts automatically. :) ps -e is saying:

5286 ? 00:00:00 FaH 5301 ? 00:00:00 FaH 5303 ? 00:00:05 FAH504-Linux.ex 5304 ? 00:00:05 FAH504-Linux.ex

Is FaH supposed to have 4 processes?

Only problems I'm having is that qd (which was supposed to install with finstall) doesn't seem to exist, and fpd is saying I'm Anonymous and Team[0], even though I entered my username and the ubuntu team number when I configured FaH.

For the curious, you must do more than background a process to detach it from a terminal.

(exec some_command) &

The '()' forks the shell into a new one (one that isn't attached to the terminal), and "exec" replaces the new shell process with the some_command process, which a) means you don't have an extra shell running, and b) starts a bit faster. I have in my ~/.bashrc a "daemon" function that will do this.

# super stealth background launch
# disconnects from launching shell, keeps running until killed
function daemon
{
    (exec "$@" >&/dev/null &)
}

daemon some_command

Now, back on topic, F@H has several processes. The FahCore_....exe processes are threads (I think) of the core, which is actually doing the work. There is also the client, which starts and stops cores and uploads results, etc. But it looks like you (GreenGirl) have two clients running, which may or may not be OK, depending on what finstall does. If you have 2 CPUs and you are not running the SMP client, you'll want one client (plus its associated cores) for each CPU.

Ugh, I'm sorry I'm being such a pain about this but does anyone know how to uninstall finstall? I want to be able to see my progress (fpd isn't working now for some reason) and now that I know how to get it running in the background without a terminal window (thanks, jpkotta) I think it would probably be better to just manually run it in the background and move it to the foreground whenever I want to see the progress, rather than have finstall handle everything.

There is a text file you can check for progress... unitinfo.txt if I recall correctly. Sorry I'm not folding at the moment!

Is FaH supposed to have 4 processes?

Yes it is, I wondered the very same thing and found the answer at folding@home forums.

After following the howto here, specifically this bit:

"For me this was all I needed as it automatically created the init scripts I needed to start after reboot. However the init scripts don't seem to work for everyone, so if you need to do it manually:

1.

Make a file called foldingathome in the /etc/init.d directory:

gksudo gedit /etc/init.d/foldingathome

2.

Paste this in:

#!/bin/sh
# /etc/init.d/foldingathome for Ubuntu
# Start the F@H service.

pushd /home/YOUR_USERNAME_HERE/foldingathome/
su YOUR_USERNAME_HERE -c "screen -d -m ./folding start"
popd

3.

Save and exit 4.

Make a symlink into the /etc/rc2.d directory:

sudo ln -s /etc/init.d/foldingathome /etc/rc2.d/S99fah

Now, when i start, the booting freezes about 4/5th of the way through.

If i stick it in recovery mode, i get to the andy@andy_desktop promt, and then it freezes, and i get a:

SOFT LOCKUP DETECTED ON CPU#0!

The exclamation mark really takes the piss... I am pretty sure it was that init.d stuff. I have tried deleting the /etc/init.d/foldingathome entry, but it makes no difference (i am using a livecd to get in there to edit the stuff).

Anyone got any ideas over this?

If you deleted the f@h stuff, it shouldn't affect the system at all. It sounds like a hardware problem. I couldn't tell you much more than that. Maybe try a different kernel?

i have tried the two kernels i have in grub. the thing is, its the only thing i changed to my system, nothing else. there's nothing it could be. i will have another bash though...

Ok...here goes...the first time I read this howto...installed it...works great(the install part)...but when I try to run it it prints this: ``` sudo /etc/init.d/foldingathome start /etc/init.d/foldingathome: 23: [[: not found /etc/init.d/foldingathome: 33: [[: not found /etc/init.d/foldingathome: 147: [[: not found /etc/init.d/foldingathome: 147: arith: syntax error: "++num"

  Sorry if it was posted before but I cannot read all the pages in this thread...and searching for it turned out nothing. Sorry for the trouble but I would like to have this running!!!

Use the script from the wiki. Link in my sig.

jpkotta said: Use the script from the wiki. Link in my sig.

Ok...thanks...works now...somebody should update the thread thou!!!

sad_iq said: Ok...thanks...works now...somebody should update the thread thou!!!

Yes. Yes they should. I've emailed the admins twice. I've tried to contact the original poster. This is why forums suck for information that has any sort of permanence. Wikis are much better for documentation. I must say that the script got much more exposure in the forums, but the howto really should have been something more like "Here's a link to the wiki page, where the real howto is. Post your problems here.". Anyway, if the admins ever get back to me, I'll redo it properly.

I need to know a few things....

First off, I have this set up on an old PC running Ubuntu.. I have it set up with no monitor, so I have tap in remotely.. I have installed and successfully can run F@H...

My question is.. If puTTY (the program I use to connect to the machine) looses its connection, will F@H still run???

Could I actually close puTTy after I starte F@H, that way I don't always have to have a connection terminal running on my other computer ??

If I do get disconnected, will F@H save its current progress for the next time, or does it start over???

Thanks all :-)

about your first question: easiest thing is to try it and see. connect, start fah, disconnect, connect again, then see if cpu is still being eaten by the fah process or not. :)

if the fah process is killed by disconnect, you could try starting the process with & at the end, which would put the process in the background... but i'm not sure if that will keep it alive.

a surefire way is to use a neat little program called "screen", which lets you run a bunch of virtual "terminals" in your shell session, and which you can connect and disconnect from between logins, so that should let you run fah even when you're not connected.

you could also run fah at boottime in an init script, which would leave it running without you having to do anything at all. :)

as to progress saving- fah periodically writes its progress to disk, so you don't lose all your work if something crashes. so no worries there.

otchster said: My question is.. If puTTY (the program I use to connect to the machine) looses its connection, will F@H still run???

If you start it correctly, yes. Use one of the scripts from the wiki (fah_install or finstall); they are written for this purpose. If you are curious, read this post: http://ubuntuforums.org/showpost.php?p=2985303&postcount=295.

screen is good too, but in this case I'd say use the scripts because they will also start it at boot time, which is almost certainly what you want.

otchster said:

It saves every 15 min by default. You can set this during the initial config or by running it with the -config (or -configonly) option.

I would like to report a bug with the latest version of the install script on the Wiki page.

I have been happily folding on my home computer (Edgy) for a couple of days so I decided to also load F@H on my work computer (Feisty). Currently there are two scripts on the Wiki page, one dated 20061219 and the other still in beta dated 20070702. I downloaded and installed the beta script to install F@H. Since I connect through a proxy at work I had to download the client manually and move it into /opt/foldingathome/config. The problem is the beta script will not recognize if a client exists at this location unless it installs the client there itself. The client version doesn't matter, nor does it matter if the client has user or root permissions. It is not recognized. However, the earlier script works fine, so now I have two computers contributing to Team Ubuntu world domination.

In case it matters, I should mention that I first had to create the foldingathome and config directories manually, since the install script didn't do it before trying (unsuccessfully) to connect to the Stanford site.

Thanks for the report. Can you download the client by hand and put it in the same directory as the install script? That was the intention for manual downloads. I will update the docs to reflect this when I get a chance.

OK, that works fine. The problem was that the install script directed me to save the client to /opt/foldingathome/config myself. Thanks.

I used the script from the wiki to set it up on my dual Core machine. The install seems to have gone well, except that the script didn't correctly identify that I have two CPUs. So, as directed, I told the script that I had two. It dutifully installed the two setups, but the second one failed to launch (so I'm only running one instance right now). I manually edited the .cfg file in /opt/foldingathome/2 to change the machineid to 2 thinking that might help (it was set as "1" like the one that's working) but that didn't seem to have the desired effect. Where'd I mess up?

I'm new to the dual-core thing and I thought it was interesting to note how the one instance would flip between cores in htop. One cpu would be reporting 100% usage for a bit, then the second cpu would be at 100% while the other one dropped to near zero. Is this normal "load balancing" that I'm seeing? Just curious.

yes, it's load balancing, when you have two cores running F@H it wont happen anymore. as for the install, i had a similar issue when i installed it on a dual processor server i had to run etc/init.d/foldingathome start each time i started the computer.

Thanks for the confirmation on the load balancing.

Had to start it manually, eh? Bummer. I don't do much in the way of rebooting... I just let 'em run. I guess I'll have to play around a bit more to see how to get that second one configured and running. I like the idea of it just running at start-up (otherwise I'll forget to restart them, or won't be here post-power interuption to get them going again).

i never did any research into it myself, it was a server and it ran 24/7, so it was not a big deal/

Hey folks, I am new to the whole Ubuntu/Linux world. My brother wants me to learn more about it so I threw it on a spare machine here at work. I wanted to get into the FAH stuff because I have extra machines sitting around, so I figured why not. Sure I could go the easy route and leave Windows on them but I hate not being able to figure something out.

Followed the posted instructions and was simple enough until I got the LOG at the bottom. (NOTE ... I originally joined the Ubuntu team but after trying it 10 different times I stopped entering it in :) )

We are behind a firewall here at work but I know that isnt the problem because we have Windows machines running FAH, unless I am just blind to something obvious. So .. where should I start troubleshooting? I found one related topic on google but it did not help me at all

Have you re-tried recently? Sometimes their servers are down for maintenance. (The 403 error indicates another issue from what I've read about it, but I'm guessing it's just a maintenance thingy.)

In about one month time(?) we will enter top 100 folding@home teams. I want that on ubuntuforums.org frontpage when it happens. It would also be nice on ubuntu.com.

I'm no people person and I cannot make it happen however. Are you and can you? That's the challenge and your time frame is approx. 1 month.

Make it happen!

freebeer said: Have you re-tried recently? Sometimes their servers are down for maintenance. (The 403 error indicates another issue from what I've read about it, but I'm guessing it's just a maintenance thingy.)

Yep ... at least 4 or 5 times a day. And it retries 11 times on its own with a minute or so intervals. I have 2 other computers and my laptop (2 XP and 1 98 ) all on the same switch running FAH just fine. So I'm trying to figure out if there is some setting in Ubuntu that would need to be changed (Which wouldn't make sense).

brandon, how did you install f@h? if you did'nt already, i would recommend FAH_install from the wiki

I just noticed that there is a version 6 of the SMP-x64 client. I am having a problem getting this to run. I have tried following the wiki but I still can't get it to go. Could this be because I'm trying to run this from the live CD?

I'm trying to learn how to work with Ubuntu while doing this so this is the first time that I'm jumping into Linux. I figured Ubuntu would be a great start :)

I think you have to pass a new switch to the client, -smp. So for example if the CLIENT OPTS used to be '-forceasm -verbosity 9' they would become '-foceasm -verbosity 9 -smp'

Seemed to work for me after a few go rounds.

glotz said: I think you have to finnish one unit for the file to appear. Here's how to setup any windoze box http://folding.stanford.edu/So, how do i verify that it is running at all?

:) Thats a good question! Just wait a few days and the file should be there. Maybe someone else knows better.

Actually, I don't think that is correct. unitinfo.txt should appear as soon as your unit is downloaded and started folding.

For example, here is the unitinfo.txt currently on my system:

Current Work Unit
-----------------
Name: p2566_BBA5_ext
Download time: October 6 15:19:46
Due time: December 27 15:19:46
Progress: 3%  [__________]

To check if it is running, look also for the file FAHlog.txt (in the same directory), which is a log of the folding progress and various messages. Also, check your CPU usage; you should have process FahCore_xx.exe (xx depends on the unit being worked on; e.g. FahCore_79.exe) taking up almost 100% CPU.

AstalaVista is that your first unit ever? That's what I meant.

glotz said: AstalaVista is that your first unit ever? That's what I meant.

Alright, that's not my first unit. But I have set-up F@H in a couple of machines, and unitinfo.txt always appeared as soon as folding started.

ant2ne said: Crap it isn't running then. I wonder what I'm doing (did) wrong!

You didn't say how you set-up your F@H. If you give more info, maybe we can help.

Actually, I now prefer the simplest method; simply put the FAH504-Linux.exe into a subdirectory of home; e.g. ~/FAH/ Then run FAH504-Linux.exe from terminal.

On one machine, I have a dual core; then I simply have two subdirectories, FAH1 and FAH2; and again, run FAH504-Linux.exe directly in each subdirectories.

This method can also be applied to running F@H in Windows. The only downside, you cannot close the terminal window.

AstalaVista said: The only downside, you cannot close the terminal window.

You do not need to keep the term open! http://ubuntuforums.org/showpost.php?p=2985303&postcount=295 I'm adding this to the wiki.

I've updated my fah_install script. Get it in the wiki (https://help.ubuntu.com/community/FoldingAtHome). It adds the 6.00(beta1) client. You should be able to update everything by running the following commands:

sudo /etc/init.d/foldingathome stop
sudo tar zcvf fahbck.tar.gz /opt/foldingathome 
sudo ./install.sh install
sudo /etc/init.d/foldingathome start

You will want to make sure you allow the installer to update the /etc/default/foldingathome file, since the 6.00(beta1) client needs an extra option for SMP work units.

AstalaVista said: You didn't say how you set-up your F@H. If you give more info, maybe we can help.I used the install script mentioned on the first page of this thread. ```

sudo ./folding_install.sh install

you might want to try the script that jpcotta was talking about , it's very good. (ps thanks for updating it, my install quit about a week ago and i couldn't figure out why for awhile.)

I've been folding for 2 years, come next month. I fold on 3 different teams.

So, first of all, thank you for your contributions, and this neato tut on setting up FAH on Ubuntu!

Secondly, I was hoping there would be a team Ubuntu, and now that I know there is, I'll be folding for "Humanity" pretty soon, as well. I am just waiting on some parts to finish rebuilding my wife's winbox, then I can take my old Dapper box back, and load up FAH using your tut.

Thanks again!

I PMed an admin to remove the attachment.

The first post of the thread is out of date, and ndhskp is not around AFAIK. So I more or less copied it to https://help.ubuntu.com/community/FoldingAtHome/Install. Feel free to improve it.

Been having a frustrating issue. After a computer crash(Very literal variety), I had to reinstall ubuntu. then i tried to reinstall my folding at home. However, It seems to install just fine. But it never creates the FAHlog.txt file. And never seems to run. when i run and sudo /etc/init.d/foldingathome status. Says the client is running And the FAHlog.txt isnt there. However, upon checks(After reading this entire post) The processes are not running. And it can easily uninstalled as if its not running. I get no increase in processor usage. Issuing the start command results in it saying the client started. But nothing changes.

I have noticed during install it claims the foldingathome group and user were created. However after several checks threw groups and users. No such group exists. When uninstalling it says it cant delete the user/group cause it doesnt exists. I have even gone to the lenghts of created the user and grp prior to install and no go.

Im running Ubuntu 7.10 Gutsy. Trying to install the SMP client. Have got the libs needed. Installed Via Wiki instructions. Using sudo. Not sure if any of this will affect anything. I have webmin installed. And also have installed a postfix server as well as a webserver.(and many other things Wow rocks on ubuntu) I keep the firewall set to allow all.

Sorry for the long post. Just wanted to get all the information I have at once. Any help would be appreciated.

Very strange. Are you running a 64-bit system? Can you post the output of the following commands?

yes im running 64 bit ubuntu. And yes its a 64 system.

On my last install attempt i checked the logs. It did infact successfully create and delete the user/group foldingathome. I also confirmed via webmin that while it was installed, The group was there and so was the user. However same fail message. An interesting note. on another computer with a fresh install of ubuntu(I borked it). It is doing the exact same thing.

On a bright note. It is installing and runing under wine.. Albeit slowly.(2 frames per min vrs 30 sec) At least i can still fold.

Btw have any of you had experince with fully setup compiz(The settings manager installed and cube going) And multi monitors(Somehow my settings borked it other computer badly) When i got the second monitor connected. It locked and killed tfter reboot i could log in however i could not get ful xserver. All i had was a tan background(no background set) even under other sesions.

All of your files look OK; it looks like the client hasn't been run except for the configuration mode, but we knew that. Try running the client manually, and post the output:

 sudo su --shell /bin/sh --command "cd /opt/foldingathome/1/ ; ./fah6 -smp" -- foldingathome

This is off topic here. If you want to discuss further, you should make a new thread.

I will say that I got it working on dual monitors in Xfce. I got the dual screen set up through nvidia-settings (twinview). Then I got compiz working, and I don't remember anything special I had to do to make it work with 2 screens. Followed this guide: http://ubuntuforums.org/showthread.php?t=623752.

ok intersting thing, Says the cleint only supports 64bit systems.... I know for a fact that this is 64 bit...

Note: Please read the license agreement (fah6 -license). Further 
use of this software requires that you have read and accepted this agreement.

This client only supports 64-bit linux machines.  Your machine was detected as ''.

Ok on second check... Some how the 64 bit installer i have installed 32 bit os,,,,guess ill have to redownload/redo my install/live CD. How do i verify my install of ubuntu is 64 bit.

My good man i must thank you for helping me find my error. I had grabed my 32 bit ubuntu CD instead of the 64 bit. I will label them to prevent further issues.(Though i will still try to find interesting ones)

Status = Happily folding

You can always check what arch you're using with the command

uname -m

or

uname -a

I installed F@H using the installation script folding.sh as directed on this howto.

However after I try to add my own user name and team name the MyFolding.html still shows Anonymous and None? I tried to change to my name/team using this...

sudo ./folding.sh --rename

The client.cfg file DOES show my new user name and team, but it doesn't seem to be taking. I have this running fine on 3 other machines.

By they way, how can we contact Christer Edwards? It looks like the wiki I listed above needs updating... It doesn't have the folding.sh script. Or am I doing it wrong.

Thanks.

The point of wikies is anybody can edit them. Feel free to.

I used the link in my signature to install F@H. Maybe give it a try.

After looking a little closer.

In this folder.../var/lib/folding/foldingathome/CPU1. FAHlog.txt says F@H recognizes my User Name and Team number.

[04:01:44] - User name: kpictjl1 (Team 68208)

client.cfg has my User Name and Team Number.

[settings]
username=kpictjl1
team=68208

however, MyFolding.html, still shows Anonymous.

Your information
User name: Anonymous
Team number: 0

mmm...so why doesn't MyFolding.html get updated? Mostly I'm not confident that this machines "work" will be reported correctly.

I filed my above issue as a bug here.

Christer will fix it in the next release, but my workaround is to delete Myfolding.htlm and then restart the service.

Where can i find the protien think gui? I thiought i found it in this thread, But have had no luck locating it Edit: NVM found it

Ok found and installed protien think. However.. All info is blank. I know for a fact. that i have a unitinfo .txt anyone know why it would be blank.

The wiki pages were getting really cluttered with all the different install methods, so I made dedicate pages for each method and just links in the main page.

[09:38:10] + Core download error (#8), waiting before retry...

i dont know what methods it uses to extract the core, but that seems to be the problem as far as i can tell. did this just start(after having used F@H for awhile)? if not (new user/install), try re-installing

OK deleted the .exe files and killed the process using system monitor and then started back up via sudo /etc/init.d/foldingathome start and what do you know, now its working fine. Really strange.

Yeah was a new install, newbie here... thanks anyhow... learning quick hehe...

I had one of mine start doing that after fetching completing a unit. Did that about 10 times. (Same core name too) Then deleted the core and moved on by itself. My guess was it was a server with a bad work packet.

Got it working on my laptop, now here a odd request, but is there a way to put in a script that stop it when the laptop is running on batteries?

Not odd at all. See the second bullet of the first post of this thread. It will tell you to go here: https://help.ubuntu.com/community/FoldingAtHome#head-353ddb49ec5a97223b3e0f1be7d8a7acfab7f59e

Is there a way to run protein_think aside from putting "python fahmain.py" in the terminal?

It's my 1st time running Linux, but I've been folding for almost a year. I just switched my 2 PS3s running 24/7 to Team Ubuntu:) They cut through WUs like a hot knife through butter

Thanks in advance

jpcotta: could FAH install be updated for 6.00 beta 2? also i believe you could create a deb if you could configure your script into a makefile. these would be awesome.

Spartan

I updated it a couple of days after the previous beta expired.

I didn't want to use a Makefile, because then people would need to install make, which AFAIK is not installed by default. I believe you only need a tarball and a few scripts for a deb, but I've never gone into the details. In any event, I like Christer Edwards's script, which just uses finstall. It just doesn't do the SMPs right yet. As soon as it does (and I haven't tried since the beta expired), I'll probably just use that.

it isn't working properly for me, i had to get the new beta off the site and run it manually. also the make script was for creating a .deb, i should have specified, but a channel from stanford with auto-updatable .debs would have been awesome.

I just retested it and it works for me. What exactly goes wrong? BTW, you need to uninstall and reinstall, I don't think update will do it for you. Perhaps "update" is poorly named; it doesn't update everything, it only updates the scripts that I wrote. This is because if you update the client, I just assumed that the WUs would not be compatible, and you'd have to start over anyway.

i figured it out: the scripts did update, and i got the client from stanford but forgot to change the user on it. everything works now.i just wish i could get all the SPARC's around campus working on it.

A new beta client is out, which means the old one is expiring soon.

http://folding.stanford.edu/English/Download https://help.ubuntu.com/community/FoldingAtHome

I tried installing with the new script, but when i go to start it it shows failed and my processor usage does nothing.

You mean that the installation appeared to be successful, but when you run ``` sudo /etc/init.d/foldingathome start

Try replacing /etc/init.d/foldingathome with the attached script.  It should print out some error messages.

well, the new script starts it fine. and based on the noise of my computer last night, i think it was succeeding but reporting failure.

Good. All that's different is that I removed the --quiet option from start-stop-daemon. The client always takes a few seconds to actually get up and running, up to several minutes if it has to up/download work units.

I just updated to Hardy on some of my machines. It seems like the Linux process scheduler is really weird. F@H is niced to 19, yet it seems like the scheduler is giving it more time than other processes. This, in turn, screws up frequency scaling. I'm still looking into this problem; I haven't seen any good workarounds.

is this 64bit or 32 bit or both? i have noticed no such issues on my 64bit system.

It's both, but was more noticable on my 32-bit machine because it's a laptop (cpufreq scaling) and it is a single core. Anyway, I found the problem: the new CFS process scheduler in the kernel. The scheduler tries to give groups of processes their "fair share" of cpu time. Apparently, the way of grouping processes is by UID. Since I run F@H as it's own user (I really think this is the correct thing to do), it was basically getting half the CPU time, and my processes were getting the other half. There is a mechanism for tuning the share of CPU time each UID gets, in /sys/kernel/uids/$UID/cpu_share. Apparently the default is for everyone to get 1024 "units", I set foldingathome to get 16 and it works much better.

<rant> I'm questioning the wisdom of adding the CFS to a desktop distribution, or at least this particular policy. When I'm on a desktop computer, *I'm* the one who's running programs; background jobs should have a low priority. CFS is probably great for servers, but I'm not convinced of its utility for desktops. </rant>

Edit: Apparently, this is already getting fixed: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/188226

Edit: The fix is to add

Well, I'm a little baffled. I've been tinkering with getting the client installed and running through out the day, and I'm hitting a wall. Maybe one of you could point me in the right direction, because I'm stumped.

My system is single-core 64-bit. I can successfully install everything, apparently, but nothing ever shows up in the system monitor. Hmmm. Look at this:

To start folding right now, run `sudo /etc/init.d/foldingathome start`.


user@Vera:~/fah_install$ sudo /etc/init.d/foldingathome start
 * Starting Folding@Home client 1                                        [ OK ] 

Looks normal, right? After seeing nothing happening, I decide to try this:

user@Vera:~/fah_install$ sudo /etc/init.d/foldingathome stop
[sudo] password for user: 
 * Stopping Folding@Home client 1                                        [fail] 
user@Vera:~/fah_install$ 

Okay, so now I'm confused. It says it starts, but never really does, since it never appears in the system moniotor, and stopping it fails. For that matter, everything fails except the start command. After dinking around with this and getting no where for the better part of a day, I decided I better ask around, since someone else may all ready know exactly what to do. I've lost enough hair today, and I'd rather keep the rest of it for as long as I can. :)

I don't really know... I'm not familiar with system monitor. I wonder if it only monitors non-root processes? *shrug*

It looks to me that it's running. Have a look at your unitinfo.txt file... you said you let it run for a while? If it's running for a while, you should see some progress. Also, after you run the start command, can you check the processes with top or htop? You should see it there.

It doesn't show up in top, either. I just checked the unitinfo.txt, and after supposedly running for over 24 hours, it still has not been created. Something is definitely not right, and I can't seem to figure out what that something could be.

hmm... I'm not sure. With top and no progress on unitinfo.txt, I'd have to conclude that it's definitely not running.

Have a look at your FAHlog.txt file. Maybe there's a clue as to what the problem might be.

I been able to make turn on and turn off buttons for folding@home, how do I tell it (in terminal) to run on just one core instead of two cores?

frbe0101 said: I been able to make turn on and turn off buttons for folding@home, how do I tell it (in terminal) to run on just one core instead of two cores?

How did you install it? Do you want to make this configurable or just permanently disable one of the cores?

If you're using the SMP client (64-bit) you can't make it use only 1 core.

Is there a way to get Folding@Home using your GPU instead of CPU?

It says in the following link that only Windows is supported at the moment:

http://folding.stanford.edu/English/FAQ-NVIDIA#ntoc8

I read somewhere you get much faster calculations using the GPU.

http://folding.stanford.edu/English/FAQ-NVIDIA#ntoc8

I read somewhere you get much faster calculations using the GPU.

That's the official FAQ, and if it says Windows only, then you need Windows. I doubt any virtualization solution will work either, since that would still use the Linux driver. It sucks because GPUs do indeed calculate faster (there is a trade off: the things they can calculate are limited), and it appears that the effort to make a Linux version isn't worth it to F@H.

Anyone think they'll release a simple installer (I do miss that days of Windows .exe).

Or least put it in the repositories (or the add/remove), and have it show up inthe "Applications" menu, AND have a grpahical client.

I installed F@H on two ubunut boxes and four winxp machines. The first time I did it with ubunut took me over and over, the second machine took about 10 minutes.

Windows took about 3 minutes.

And the windows has a graphical interface so I can see that it is working.

I know I can do all these things with command line, but to firgure it out the first time is a pain.

sorry for the rant.

It's a good rant but on wrong forum.

Christer Edwards is working on a .deb and getting it in the repos. https://help.ubuntu.com/community/FoldingAtHome/origami

As far as graphical client goes, try the Windows one in wine maybe? The console one is better anyway, because it runs all the time, even when no one is logged in (in both Windows and Linux).

I'm still new to ubuntu and still trying to get a the flow of things, but I'm not giving up on it. It's on my main rig and I can get from it and into the other 2 machines to put files or get files. But I haven't been able to get F@H on my main rig. I keep messing up some where, So is there a place I can like get spoon fed on how to do it. A friend told me to get "Beginning Ubuntu Linux- From Novice to Professional". Which I did, just got it. But I like to fold while I'm reading it.

https://help.ubuntu.com/community/FoldingAtHome/origami

It doesn't get much more automatic than that. There are other methods too, see the main page at https://help.ubuntu.com/community/FoldingAtHome.

So I've managed to to folding install... I have and Instal Core2 Duo, but it only detected one core. I'm looking for a way to install another single core client beside the one I already have, but with a differnet machine number (so it uses a differnet core). I tried running the install.sh, but it says a client is already installed and will only accept 'reinstall' and 'uninstall'.

So how do you pull off running two single core clients at the same time?

Thanks,

Josh

I assume you're using the script from https://help.ubuntu.com/community/FoldingAtHome/fah_install. In that case, it tells you how many cores it detected, but in case it's wrong, you can specify the actual number. You must uninstall and then install. "update" is not what you're looking for (see the wiki page above). Also, if you are running a 64-bit OS, you should only run one client.

Therein lies my problem... it never gave me an option as to how many cores I have, and I installed the 32-bit client, so it should have. I have no idea what to do.

spudgunner, try the new script in the wiki.

For anyone running Protein Think. I just finished a new release of Protein Think (0.0.5-a) that addresses the couple of problems people were encountering. My ability to test the application is limited, however, so if you run into any problems with it, please let me know.

Get it here.

This release fixes:

• Difficulty reading new unitinfo.txt files
• Difficulty in which program would fail if certain data was not available. Now it will continue running, even without this non-critical data

Enjoy!

PS - If anyone happens to be folding on a multicore machine, you could help me by copying folders 1 and 2 and sending them to me. I want to upgrade PT to handle multiple cores, but don't have access to one. Thanks.

I'm trying to install F@H on 8.04 server and when I try to start fah, it says: "No such file or directory."

I'm currently using (or trying to use) the F@H Linux SMP 6.23 beta R1 client.

# ls
fah6 mpiexec
# ./fah6
bash: ./fah6: No such file or directory
#

Help? Please?

*edit* n/m. Got it.

For Ubuntu 8.04 Server AMD64, you need to run

$ sudo apt-get install ia32-libs

in order for it to run properly.

I have had F@H installed for the last several weeks or so and installed it using the finstall method listed in the Ubuntu wiki documentation. However, I found that even after several weeks, so statistics were being sent to the F@H site. This caused me to question whether any data was being sent. I decided to remove F@H and try re-installing using a different method.

I downloaded origami through aptitude and looked up the proper command to install it (sudo origami install etc..) but I receive the following error:

###############################################

the root user shell must be /bin/bash #

###############################################

However, I'm 99% sure my shell is bash but to check I performed the following: $sudo -i #ps -p $$ which yields: PID TTY TIME CMD 2129 pts/0 00:00:00 bash

I've tried everything I can find via Google and searching the Ubuntu forums for related issues didn't help much. I hope someone in this thread can help out. Thank you.

The heavy-handed workaround is to link /bin/sh to /bin/bash:

sudo ln -s /bin/bash /bin/sh

Heavy-handed is oft a word accompanied by trouble down the line. What makes this approach unfavorable? Is there any other approach that might solve the problem with a bit more.. finesse?

It really shouldn't cause any problems. Bash syntax is supposed to be a superset of Bourne shell syntax. A few releases ago, Ubuntu made Dash the default /bin/sh, which broke a lot of things that assumed that /bin/sh was actually Bash. The converse or this is false - anything that works for Dash should work for Bash.

The proper fix would be to either make root's shell bash (which it appears to be already), or to fix whatever is spitting out the warning.

To be sure that bash is actually root's shell, check

cat /etc/passwd | grep root

It should look something like this:

root:x:0:0:root:/root:/bin/bash

I would ask origami's author about it: https://bugs.launchpad.net/origami

I ran the command you listed in your reply and got this:

I will ask the author as well, but could it be that if I change the line above the look like this:

root:x:0:0:root:/root:/bin/bash

..that I won't break anything and perhaps satisfy the origami installer?

edit #1: I decided to go and test my theory and sudo -i works without any warning, so bash is being called correctly I assume (unless a system restart is required to institute the changes I made in /etc/passwd). Origami's installer finished but the startup script failed to start. This is an problem related to my processor though so I'll work on sorting that out next.

Yes. It should always be an absolute path anyway, for security reasons. I believe the proper way to do it is with

sudo usermod --shell /bin/bash root

Well, origami has apparently installed successfully but when I run sudo origami start, the following happens:

Starting up FAH client(s) on 1 processor(s):
Starting FAH client at CPU1...
FAH client #1 startup: OK 


Starting of FAH client(s): FAILURE

I'd love to read the log file or something on this but I haven't found it ... yet. I'm starting to think maybe origami is more trouble than its worth and to just download the client off their site.

(Sorry for the thread jack, I couldn't find a better place for this, and I didn't think it was worth its own thread)

I'm running F@H on a dual-core laptop that gets used by the whole family, and we typically log out when we're done, so there's a fair amount of time that the laptop spends sitting around, with only the screen turned off, with nobody logged in. Since F@H technically runs as a process of its own user (that _is_ right, correct?) is it still running when no humans are logged in?

BTW ranked #472 on TeamUbuntu, top 15% F@H wide

paintandswim09:

This is more or less the official F@H help thread for Ubuntu. You're not off topic.

It depends on how you installed it. If you used one of the scripts from the wiki, then it should be running when no one is logged in. You can check by running top or another process monitor and seeing how long the F@H processes have been running when you first log in.

i modified the install.sh to download the newer 6.24beta smp client

How do I remove folding@home from the startup script? I still would like to run it but no longer want it to run automatically on startup.

Assuming the init script is called "foldingathome",

sudo update-rc.d -f foldingathome remove

You could also use something like sysvconfig.

Why all my FAHCORE_A2.exe processes are using least than 10% of CPU each one?

Not really. Nothing looks weird in your logs. Although I don't think you need the -local option on Unix, and I'm not sure if -smp takes an arguement.

You could try the official forum http://foldingforum.org/. You could also try purging F@H from your system and reinstalling.

Hello everybody! I just wanted to throw out a reminder to everyone here, as well as anyone who may stumble upon this looking for help. The Ubuntu Folding@Home Team does have it's own IRC channel!! It's up and running strong again, and hopefully it can be a great resource for those looking for help getting F@H setup, or troubleshooting any issues you may be having. If nothing else, come hang out and we can shoot the breeze and talk about folding!

So come on by, and check us out on #ubuntu-folding on the FreeNode network! We look forward to seeing you guys there!!

Hi all, looks like the wiki ( https://help.ubuntu.com/community/FoldingAtHome ) is not up-to-date (see ppa for origami for example... ), can someone update it please?

Which of the install methods you think is the easiest one for a "standard install": laptop with one CPU on Ubuntu 9.04, and i would like to have the possibility to start/stop F@H via a button or command line. If possible i would like also to control which % of the CPU is used by F@H.

thanks in advance for your answers!

Well, you're in luck...

I *just* got done updating quite a bit on the Origami Wiki page so feel free to check it out. I haven't gotten to the main Folding@Home wiki page yet, but I'll work to get it caught up a bit.

As far as which method would be easiest to use, stable, and easy to monitor... that would of course have to be origami :) It's also what I run on my single-core, 9.04 laptop, so if you ever have any issues/questions I may be able to lend some advice.

It takes two commands to install, one command to check your progress, and can be stopped/started by a simple command as well. All of the info you could need is on the wiki page I linked. However, origami has it's own wiki if you'd like to check it out as well: http://origami.zelut.org/doku.php

As far as having the F@H client only use a certain % of your CPU - I don't know of a way to do that currently. The way the client works is by using your 'spare' processing power. It has very low priority, so any programs, apps, etc. that you run will still receive all the CPU power that they want. Then, whatever power isn't being utilized will go to the F@H client. This way, you won't notice any system lag, lack of power, or any other ill-effects from the F@H client, but it also does as much folding as possible. Since it works this way, it will keep your CPU at 100% no matter what you're currently doing on your computer.

Welcome to the fold, YannBuntu ):P

Thanks a lot, i will test it, and that will help me update the ubuntu-fr wiki too :)

Just a remark: here https://help.ubuntu.com/community/FoldingAtHome/origami#Ubuntu%20PPA%20(.deb) you should remove Dapper and Gutsy as ubuntu desktop is not supported any more for thoses versions. Also you could add Jaunty (and Karmic) if there are PPA..

YannBuntu said: ...should remove Dapper and Gutsy as ubuntu desktop is not supported any more for thoses versions...

Dapper server is supported until June 1, 2011. I think Gutsy is completely unsupported.

@all: some questions: - with origami, how can I start/stop the folding process? (i think it is possible with the "finstall" F@H installer) - how can I add/remove origami from the "applications that start at the beginning of my session"? - is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)

I think these informations should be in the wiki...

other question: is the the "finstall" F@H installer still working on Ubuntu 9.04 ? (last update of the wiki was in June 2008...)

@jpkotta: you are right! :)

YannBuntu said: @all: some questions:

- with origami, how can I start/stop the folding process?

sudo origami stop

and

sudo origami start

- how can I add/remove origami from the "applications that start at the beginning of my session"?

Origami auto-starts by itself on bootup. However, there has been a conflict between the usplash used in Jaunty and several programs which auto-start by default (origami being one of them). This is still being tested with 9.10, but it appears that this will no longer be an issue. For the time being, you can either run:

sudo origami start

to start origami after bootup, or disable usplash. There have been users who have reported that by removing usplash several of their programs that are set to auto-start worked as they should.

• is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)

No, I don't believe there is. If there is something available to do this, it would be a third-party app, and I do not know of any offhand. If you have a multi-core CPU, you should be able to limit the program to only one core, and this would effectively reduce your CPU usage to 50% (on a dual-core).

I think these informations should be in the wiki...

You raise a very good point here. I will make a note to include more info on how to stop/start origami, as well as a section for FAQ.

other question: is the the "finstall" F@H installer still working on Ubuntu 9.04 ? (last update of the wiki was in June 2008...)

I believe it is still functional under Jaunty. I tried it out fairly recently, and I don't recall encountering any issues.

YannBuntu said:

- is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)

Now that I think about it, there is a note in the wiki about this. https://help.ubuntu.com/community/FoldingAtHome#cpulimit

*However*, F@H should run at a low enough priority that it should not kick up the frequency of your CPU. In my experience, even at 100% CPU usage, the fan is not needed at the lowest frequency. You should verify that you have frequency scaling enabled, and that F@H is not kicking it up.

Thanks a lot for your quick answers! :KS
