Air Force's Maui Center Selects Cray XD1 Supercomputer to Boost Space Surveillance and Image Processing Capabilities.

SEATTLE -- The Maui High Performance Computing Center (MHPCC), a U.S. Air Force Research Laboratory's Directed Energy Directorate facility, has chosen a Cray XD1(TM) supercomputer to increase the center's capabilities in space surveillance and image processing, according to global supercomputer leader Cray Inc. (Nasdaq:CRAY). This marks the first time MHPCC has acquired a supercomputing system from Cray. This order is part of a multi-order award with an aggregate value of over $23 million that Cray has received from the Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP).

A Cray XD1 system with 288 AMD Opteron(TM) processors and peak performance of about 1.4 trillion calculations per second (teraflops) will soon begin to advance the work of the Maui Space Surveillance Site (MSSS). Located at the summit of Haleakala on the island of Maui, this unique site can gather data on near and deep space objects at night or in daylight.

"The Cray XD1 supercomputer is ideally suited for handling the vast quantities of data and analysis driven by our space surveillance activities," said Major Kevin Benedict, Director of MHPCC, "We look forward to a mutually beneficial relationship with the new Cray Inc."

The MSSS combines operational satellite tracking facilities with research and development projects. For more information about MSSS, go to http://www.globalsecurity.org/space/systems/msss.htm.

"We are honored to have the MHPCC become a Cray customer for the first time in the history of their supercomputing center. Using our innovative Cray XD1 system for the important Space Situation Awareness mission of the Maui Space Surveillance Site is also an important new application for us," said Peter Ungaro, Cray senior vice president of sales, marketing and service. "This will be the largest Cray XD1 system in the world, so we are very excited to scale it to higher and higher levels of performance and capability and are looking forward to continue to push the technology even further."

About the Maui High Performance Computing Center

MHPCC is an Air Force Research Laboratory Center managed by the University of Hawai'i. Ranked as one of the top supercomputer sites in the world, MHPCC provides world-class, parallel computing capability to the research, science, and warfighter communities. MHPCC is also an allocated Distributed Center of the DoD High Performance Computing Modernization Program, providing over 6,000,000 hours of computing time per year to support high priority military research efforts. MHPCC is a national resource chartered to support a diverse base of DoD and other government users, facilitating the collaborations requisite to solve today's complex computational problems.

About the HPCMP

The High Performance Computing Modernization Program was initiated in 1992 in response to Congressional direction to modernize the DoD laboratories' high performance computing (HPC) capabilities. The HPCMP provides the supercomputer services, high-speed network communications, and computational science expertise that enable the defense laboratories and test centers to conduct a wide range of focused research, development, and test activities. This partnership puts advanced technology in the hands of U.S. forces more quickly, less expensively, and with greater certainty of success.

About the Cray XD1 Supercomputer

The Cray XD1 is rapidly winning customers around the world. This exciting new system lets users experience the performance and reliability of Cray supercomputing technology in systems that scale from small to highly parallel. The Cray XD1 provides scientists and engineers with a platform purpose-built to meet their high performance computing challenges, and is an attractive alternative to the challenge of managing clusters assembled from general-purpose business servers.

The Cray XD1 supercomputer features the direct connect processor (DCP) architecture, which removes PCI bottlenecks and memory contention to deliver superior sustained performance. The Cray XD1 system has the lowest latency of any current HPC system, with MPI latency of 1.8 microseconds in measured tests conducted using the Ohio State MPI benchmark.

Safe Harbor Statement

This press release contains forward-looking statements. There are certain factors that could cause Cray's execution plans to differ materially from those anticipated by the statements above. These include the technical challenges of developing high performance computing systems, government support and timing of supercomputer system purchases, the successful porting of application programs to Cray computer systems, the successful passing of acceptance tests, reliance on third-party suppliers, fluctuating quarterly operating results, lower margins and earnings due to significant pricing pressure, Cray's ability to keep up with rapid technological change, Cray's ability to compete against larger, more established companies and innovative competitors, and general economic and market conditions. For a discussion of these and other risks, see "Factors That Could Affect Future Results" in Cray's most recent Quarterly Report on Form 10-Q filed with the SEC.
