[/I] * The Cray XT5 supercomputer known as "Jaguar" has finally clawed its way to the title of fastest computer in the world. *
*Jaguar beat out the competition by showing it can process 1.75 petflop/s, or quadrillions of floating point operations per second, according to the Top500 Linpack benchmark. IBM's Roadrunner was pushed back to No. 2 by posting a processing speed of 1.04 petaflop/s, a dip from the 1.105 petaflop/s it reached in a June 2009 test. The slower performance this time around is apparently due to a repartitioning of the system. *
*Kraken, another Cray XT5 system, jumped up two places from its former No. 5 position by posting a processing performance speed of 832 teraflop/s. IBM's BlueGene/P, from Forschungszentrum Juelich in Germany, came in at No. 4 with 825.5 teraflop/s. At No. 5 is China's Tianhe-1, the highest ranking ever for a Chinese supercomputer. * *The top 10, while still dominated by supercomputers housed in the United States, had just one newcomer. That would be Sandia National Laboratories' "Red Sky," a Sun Blade system that posted a Linpack performance of 423 teraflop/s. * *Just as the last time the list was released, the Top500 list is made up mostly of Hewlett-Packard and IBM computers. HP accounted for 210 of this year's 500, and IBM 185. In terms of processors in use, Intel still enjoys the lion's share, with 80 percent. _The most popular operating system is Linux, with 90 percent of the Top500. _*
- Sitting back at No. 2 on the Top500 list of supercomputers for more than a year, Jaguar overtook IBM's "Roadrunner" according to the twice-yearly list that will be unveiled Tuesday at the SC09 Conference in Portland, Ore., this week. *
- Every six months when the Top500 List is released the threshold to grab a place on it gets higher. The slowest supercomputer (No. 500) on November's list posted a speed of 20 teraflop/s, up from the 17.1 teraflop/s of six months ago. In other words, what is the slowest computer this time around would have been No. 336 in June. *
- Here's the Top 10: *

An even bigger reason to run Linux. :D:D
I wonder what a 1.75 petaflop/s supercomputer would cost? Better yet, would it fit in my basement? :P
