Thirty-three years after the first Cray-1 supercomputer, the company is still cranking them out. Now the Cray XT5 “Jaguar” just won the title of world’s fastest computer, displacing the IBM Roadrunner that held the title for the previous 18 months, InformationWeek reports.
The Jaguar features six-core AMD Opteron processors, nearly a quarter million total CPU cores, and managed to hit 1.75 petaflops per second on the Linpack benchmark used by researchers in determining the biannual Top500 list. That’s compared with the Roadrunner’s 1.04 petaflop/s rating. (A petaflop/s is one quadrillion calculations per second.)
Of the top 500 machines in the list, 399 use Intel processors, 52 employ IBM Power chips, and AMD brings up third place in popularity with 42 systems. HP and IBM together account for building almost 400 of the 500 computers. Anyone for Crysis benchmarks?
