Cray, once synonymous with "supercomputer," has finally edged out the competition and for the first time won the world's fastest supercomputer award from Top500.org. Look for Cray to increase its market share in the next few years. R.C.J.
Cray's XT5 supercomputer at Oak Ridge National Laboratory has claimed the "world's fastest supercomputer" crown from IBM's Roadrunner, according to the Top500 list announced at Supercomputer 2009 (Nov. 14-19, 2009, Portland, Ore.) For the last two years, IBM's Roadrunner supercomputer has edged out Cray on the Top500 list, but this year Cray's XT5 finally beat Roadrunner with a 1.75 petaflop/second performance speed running the Linpack benchmark (compared to 1.1 petaflop for Roadrunner). The Top500 list reported that Jaguar has a theoretical peak capability to 2.3 petaflop/second.
