Cray Releases Latest Version of Its Linux Operating System Equipped With New Cluster Compatibility Mode

SEATTLE, WA and DEARBORN, MI, Apr 14, 2010 (MARKETWIRE via COMTEX) --At the 2010 High Performance Computing (HPC) User Forum in Dearborn, Michigan, global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced the release of the latest version of its Cray Linux Environment -- the production petascale operating system for the company's line of Cray XT supercomputers. This third generation of the Cray Linux Environment includes the introduction of Cluster Compatibility Mode, allowing Cray XT supercomputers to run applications from Independent Software Vendors (ISVs) without modifications.

"Scalability is a key component of designing Cray supercomputers and this latest version of our Cray Linux Environment continues to be one of the most scalable Linux environments for high performance computing," said Barry Bolding, Cray's vice president of scalable systems. "The introduction of Cluster Compatibility Mode significantly enhances the compatibility features of our operating system. Now the most powerful supercomputers in the world can run our customers' key ISV applications right out of the box."

Shipping with the Cray XT6 and Cray XT6m systems, with availability planned for the Cray XT5 and Cray XT5m systems later this year, the third generation of the Cray Linux Environment is an adaptive operating system purpose-built for HPC. Cray Linux Environment is designed for performance -- the operating system scales to more than 500,000 cores; reliability -- it includes Cray's NodeKARE diagnostic functionality to ensure compute jobs are run on healthy nodes; and compatibility -- it leverages standardized Linux to easily support a broader set of applications.

One of the most important features in this latest version of the Cray Linux Environment is the introduction of the new Cluster Compatibility Mode, which provides users with a full-featured cluster environment. Cluster Compatibility Mode is a fully standard x86 Linux environment that allows for simple, out-of-the-box installation and running of parallel ISV applications without porting, re-linking or recompilation. Cluster Compatibly Mode also allows for multiple MPI libraries.

"The introduction of the Cluster Compatibility Mode into the latest Cray Linux Environment furthers the company's drive to expand its total addressable market, especially into the midrange of the supercomputer segment," said Earl Joseph, IDC program vice president for HPC. "The Cluster Compatibility Mode is targeted at leading HPC independent software vendors and is designed to ensure that their applications easily integrate with Cray's line of XT supercomputing systems, allowing the company to reach a larger base of HPC users than was possible in the past. Cray's strategy is to pair the strength of its performance-focused Cray XT systems with more easy-to-install ISV applications to form an attractive combination."

"SIMULIA and Cray have worked closely for several years to ensure that SIMULIA's Abaqus FEA software operates efficiently on Cray computing systems," said Matt Dunbar, Chief Architect, SIMULIA. "With the launch of the Cluster Compatibility Mode, Cray has made significant improvements which expand the computing options for Abaqus users. It is now possible to run Abaqus on Cray XT supercomputers without the need for porting or modifications."

"Accelrys scientific modeling software can now run on the Cray XT line of supercomputing systems without porting or modifications," said Paul Burrin, Senior Vice President and Chief Marketing Officer, Accelrys. "We are thrilled that Cray's Cluster Compatibility Mode now gives us the ability to make our applications available on these high-end platforms. Some of our customers need higher levels of performance and scalability to address demanding problems, and Cray's latest OS release makes the powerful Cray XT line available to our customers."

"The third generation of the Cray Linux Environment has given our company the opportunity to reunite ourselves with Cray, which is truly significant since CEI was spun out of Cray Research in 1994," said Anders Grimsrud, President, CEI. "Our EnSight visualization software did not previously run on Cray supercomputers, but with the new Cluster Compatibility Mode, our EnSight Gold application worked simply and without the need for porting. Cluster Compatibility Mode is a game-changing feature in Cray's latest operating system, and we are pleased to again be a part of the Cray computing environment for HPC."

About the Cray XT Supercomputer Series

As the world's most scalable Linux supercomputer, the Cray XT product line combines unprecedented sustained application performance with exceptional manageability and reliability, and lower cost of ownership for customers. Using powerful AMD Opteron processors, the Cray XT line is optimized for memory-intensive and/or compute-biased workloads. The successful Cray XT product line features ECOphlex technology -- packaging and design features that promote energy savings along two dimensions: by enabling greater system density and by reducing the need for expensive air cooling and air conditioners. Additionally, the Cray Linux Environment enables optimized performance across a broader range of applications.
