, a leading builder of supercomputers, this week announced the launch of the company’s new production hybrid supercomputing system – the XK6 supercomputer. The highly anticipated new supercomputer will combine ’s Gemini interconnect, 6200-series processors (code-named “”) and 20-series compute cards.

“We built the world’s first production petaflops system with the Cray XT5 supercomputer, reinvented high performance networking with the Gemini interconnect, and we are now redefining accelerator-based supercomputing with the unified GPU and scalar technologies built into the Cray XK6 system,” said Barry Bolding, vice president of Cray’s product division.

A powerful addition to Cray’s line of highly-advanced supercomputers, the Cray XK6 system pairs AMD’s next-generation Opteron processors with up to 16 cores code-named Interlagos powered by the micro-architecture (up to 96 per cabinet) and Nvidia Tesla X2090-series compute cards (up to 96 per cabinet) 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 with up to 70TFLOPS of compute performance per cabinet. The Cray XK6 compute blades can also be blended with Cray XE6 compute blades into a single, multi-purpose supercomputing system.

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.

The Cray XK6 system introduces an new approach to increasing programmer productivity with a unified x86/GPU programming environment that includes tested and powerful tools, libraries, compilers and third-party software. When combined with the Cray Linux Environment, the result is a fully integrated Cray supercomputer that blends scalable hardware, software and a network. Cray XK6 customers will be able to utilize the capabilities of a multi-purpose supercomputer designed for the next-generation of many-core, high performance computing (HPC) applications.

“Every aspect of the Cray XK6 has been engineered to meet the real-world performance demands of researchers and scientists tasked with solving the world’s grand challenges. [...] We are leveraging our expertise to create a scalable hybrid supercomputer – and the associated first-generation of a unified x86/GPU programming environment – that will allow the system to more productively meet the scientific challenges of today and tomorrow,” added Mr. Bolding.

The Swiss National Supercomputing Centre (CSCS) in Manno, Switzerland is Cray’s first customer for the new Cray XK6 system. CSCS, which develops and promotes technical and scientific services for the Swiss research community in the field of HPC, signed a contract with Cray to upgrade its Cray XE6m system, nicknamed “Piz Palu,” to a multi-cabinet Cray XK6 supercomputer.

“GPUs are playing an increasingly important role in high performance computing as researchers and scientists look to augment the CPU performance on certain codes. Cray is a leader in the high-end of the supercomputing market and has designed, built and installed some of the world’s most powerful systems. The company has decades of experience in successfully integrating hybrid processor types into large scale systems. This strategy of hybrid supercomputing is extremely valuable, and Cray is in a good position to take advantage of it,” said Earl Joseph, IDC program vice president for HPC.
