InformationWeek reports Cray's new XK6 supercomputer promises a whopping 50 petaFLOPS:
The Cray XK6 Supercomputer handles it with a combination of AMD's 16-core, x86 Opteron 6200 Series server processors with Nvidia's Tesla 20-Series graphics processors and Cray's Linux-based operating system called Gemini interconnect. It is the first time Cray incorporated GPUs into a high-performance supercomputer system.
Cray said it could have released the XK6 earlier, but that it took about a year and a half to create the software that could integrate the GPUs. The software of the XK6 consists of a Linux OS based on SUSE enterprise OS 11, layered with Cray's own programming, Barry Bolding, vice president of Cray's product division, said in an interview.
