AMD Virtualization Journal on Ulitzer
The world's most powerful supercomputer is Jaguar, the recently upgraded Cray XT5 rig at Oak Ridge National Laboratory in Tennessee, according to the new semi-annual Top500 list. Jaguar's roughly 250,000 processors went from quad-core Opterons to six-core Istanbul Opterons and now delivers 2.3 petaflops of theoretical peak performance or 1.75 petaflops on the Linpack benchmark, dethroning IBM. Four of the top five machines are now AMD-based. This and Intel's money too. My, my. It's Cray's first time in the top spot. HP's got 210 of Top500 machines; IBM's got 186. China's got number five.
