Japan Science and Technology Corporation Orders Cray XT3 Supercomputer for University of Tokyo Software Research

Global supercomputer leader Cray Inc. (Nasdaq:CRAY) today announced that the Japan Science and Technology Corporation (JST) has ordered a Cray XT3 massively parallel processing (MPP) supercomputer.

The system will be used primarily by Dr. Akira Nishida's group at the University of Tokyo's Department of Computer Science, for testing new software libraries for large-scale simulations.

"The goal of Scalable Software Infrastructure (SSI) project is to develop parallel libraries with superior scalability and portability features. These are the fundamental tools needed to use increasingly large computing resources effectively," Dr. Nishida said.

"Cray is proud that the Japan Science and Technology Corporation has selected the new Cray XT3 supercomputer for this important initiative to advance the state-of-the-art in parallel libraries," Mamoru Nakano, president of Cray Japan. "We expect the whole high performance computing community to benefit from the work of Dr. Nishida and his group."

About JST

A research funding agency under the Ministry for Education, Culture, Sports, Science and Technology (MEXT), the Japan Science and Technology Corporation (JST) supports both basic and applied research in a broad range of disciplines and through a variety of programs and funding schemes. The JST program on "Basic Technologies and Software Tools for Large-Scale Simulations" is a leading effort to develop new software tools for high-end scientific and technical computing.

About Cray Inc.

The world's leading supercomputer company, Cray Inc. pioneered high-performance computing with the introduction of the Cray-1 in 1976. The only company dedicated to meeting the specific needs of HPC users, Cray designs and manufactures supercomputers used by government, industry and academia worldwide for applications ranging from scientific research to product design, testing to manufacturing. Cray's diverse product portfolio delivers superior performance, scalability and reliability to the entire HPC market, from the high-end capability user to the department workgroup.

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 successful porting of application programs to Cray systems 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.
