Cray today announced new hybrid supercomputing system – the Cray XK6 supercomputer that combines CPU and GPU power to achieve higher performance. The new supercomputer will combine Cray's Gemini interconnect, AMD Opteron(TM) 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) of compute power. The performance offered by Cray XK6 will be 5 times better than IBM’s 10-petaflop supercomputer.

The XK6 uses an innovative approach to increase programmer productivity with a unified x86/GPU programming environment that includes tested and powerful tools, libraries, compilers and third-party software. The Cray XK6 system pairs industry-leading HPC technologies from AMD and NVIDIA to create a true hybrid supercomputer with intra-node flexibility. By combining AMD Opteron processors with NVIDIA GPUs, the compute node in the Cray XK6 system gives users the option to run applications with either scalar or accelerator components.

The Swiss National Supercomputing Centre (CSCS) in Manno, Switzerland is Cray's first customer for the new Cray XK6 system. CSCS signed a contract with Cray to upgrade its Cray XE6m system, nicknamed "Piz Palu," to a multi-cabinet Cray XK6 supercomputer.

Upgradeable from Cray XT4, Cray XT5, Cray XT6 or Cray XE6 systems, the Cray XK6 system is expected to be available in the second half of 2011. It can be configured in a single cabinet with tens of compute nodes, to a multi-cabinet system with tens of thousands of compute nodes.
