Cray Jaguar Named Fastest Supercomputer


The Cray XT5 supercomputer known as Jaguar has won the title of world's fastest computer, ending the 18-month reign of IBM Roadrunner. An upgrade from quad-core to six-core Opteron processors from Advanced Micro Devices boosted Jaguar's performance to 1.75 petaflop per second, easily surpassing Roadrunner's 1.04 petaflop/s, according to the biannual Top500 list released Monday at the SC09 Conference in Portland, Ore. A petaflop/s refers to 1 quadrillion calculations per second. The Cray XT5 supercomputer known as Jaguar has won the title of world's fastest computer, ending the 18-month reign of IBM's Roadrunner. The Linpack benchmark is used in determining the rankings of the Top500 list compiled by researchers at the University of Mannheim, Germany, NERSC/Lawrence Berkeley National Laboratory, and the University of Tennessee, Knoxville.
