Business Editors/High-Tech Writers

SEATTLE--(BUSINESS WIRE)--April 23, 2001

Global supercomputer leader Cray Inc. (Nasdaq:CRAY) today announced a $1.6 million order from the Ohio Supercomputer Center (OSC), Columbus, Ohio. The Cray SV1(TM) supercomputer and scheduled enhancements will support advanced research on air pollution transport, brake efficiency and other problems in computational chemistry, mechanical engineering and related fields.

Under the contract terms, OSC's 16-processor Cray SV1 supercomputer system was expanded in December 2000 to 32 gigabytes of memory. This system will be upgraded in mid-2001 to Cray SV1ex(TM) processors and memory, with memory doubling to 64 gigabytes, company officials said.

"The opportunity to work with the new Cray helps us provide a powerful high-end supercomputer to our Ohio faculty. With the SV1ex, we'll have the latest Cray system," said OSC High Performance Computing Director Al Stutz. "Another advantage of this agreement is that OSC staff will be working directly with Cray on the training program for Cray's entire customer base."

Separately, Cray said it is contracting with OSC to complement Cray's staff in providing specialized training to Cray supercomputer customers, including courses in areas such as data migration facility.

"Our long-standing relationship with OSC is a true partnership in which Cray provides leading supercomputers and OSC's world-class research community provides valuable input for our future systems," said Cray Inc. chairman and CEO Jim Rottsolk. "Now we're expanding this partnership by using OSC's superb training staff to supplement our own highly skilled personnel."

The Cray SV1 supercomputer was named one of the "Best Supercomputers" for 2000 by the readership of Scientific Computing & Instrumentation magazine. Co-winner of the award was the Cray T3E(TM) product. More than 100 Cray SV1 systems have been installed since general availability began in August 1999. Half of that volume has come from outside the United States.
