XK6 Supercomputer 

The XK6 supercomputer combines Cray’s Gemini interconnect, AMD Opteron 6200 Series processors (code-named “Interlagos”) and NVIDIA Tesla 20-Series GPUs to create a tightly-integrated supercomputing system upgradeable to more than 50 petaflops (quadrillions of operations/second). The system increases programmer productivity with a unified x86/GPU programming environment that includes tested and powerful tools, libraries, compilers and third-party software. Pairing HPC technologies from AMD and NVIDIA, it creates a true hybrid supercomputer with intra-node flexibility. The compute node in the system gives users the option to run applications with either scalar or accelerator components.
