K Computer

The supercomputer is powered by 705,024 of Fujitsus SPARC64 processors spread over 864 server racks. When the system entered the list at No. 1 in June, it marked the first time since 2004, when Fujitsus Earth Simulator was knocked off the perch, that a Japanese computer headed the list.

Developed by the Chinese National University of Defense Technology, the Tianhe-A1 was knocked off the top of the list in June by the K Computer. Powered by more than 14,000 Xeon X5670 chips and more than 7,000 GPUs from Nvidia, the system, installed at the National Supercomputing Center in Tianjin, has hit a peak of 2.5 petaflops.

Installed at the Oak Ridge National Laboratory in Tennessee, the Jaguar supercomputer is powered by Crays XT5-HE technology powered by AMDs six-core Opteron chips. The system, which has hit a peak of about 1.75 petaflops, is about to be revamped by Cray using AMDs new 16-core Opteron 6200 chips and GPUs from Nvidia. Once completed, the new system—dubbed Titan—will have theoretical peaks of 10 to 20 petaflops.
