MPI dual core

I am taking a class in parallel computing, we have access to a super computer center through ssh but it is a very busy server right now and I cant get a hold of any nodes.

I want to install MPI on my dual core so that I can test without dealing with the cluster until I have a finished product.

I installed MPI but it is only recognizing one node, does anyone have any experience with MPI and dual core processes and know how to make it recognize both cores?

thanks.

One thing you can do is set up a virtual machine and use that as the second node.

You can do something like:

$ echo <your_ip_address> > my_machine
$ mpirun -np 4 -machinefile my_machine <other_arguments>

This would make MPI run on machines listed in the my_machine file. It will start all 4 (as in above example) on the same IP address. If you setup a virtual machine, you can add it to the my_machine file too (in a new line) and the processes will be distributed.

This is what I am currently using. Hope this works.

Hi,

I'd like to learn how to use MPI on my dual core laptop. Could you please give me the steps to follow before i can run mpirun? thanks
