SEATTLE--(BUSINESS WIRE)--May 23, 2000

National Cancer Institute, Naval Research Laboratory Named Two

of Five Finalists in the Science Category

Cray Inc. (Nasdaq NM: CRAY) announced today that Cray SV1(TM) and Cray T3E(TM) supercomputers provided the computational muscle behind pioneering research that earned finalist status for the National Cancer Institute's Advanced Biomedical Computing Center and the Naval Research Laboratory in the 2000 Computerworld Smithsonian Awards (CWSA). The Computerworld Smithsonian Program will announce this year's award recipients on June 5 during the Program's Annual Award Gala at Washington, D.C.'s National Building Museum.

"The National Cancer Institute and Naval Research Laboratory should be considered as outstanding among this year's 444 nominations," said Daniel Morrow, executive director of the Computerworld Smithsonian Program. "Their innovative work represents some of the very best in an extraordinary class of Laureates in the 2000 Collection."

Specifically, the National Cancer Institute (NCI) used a Cray SV1 supercomputer to simulate the behavior of proteins and enzymes implicated in cancer and AIDS to identify what drives the diseases' growth. By simulating an enzyme's behavior and interaction with other chemicals within human cells, NCI has opened the door to the design of a more effective drug that would block the enzyme's activity and provide a model for future drug discovery.

Using a Cray T3E supercomputer, the Naval Research Laboratory (NRL) developed a global ocean model to enable the prediction of ocean behavior, which will in turn provide more accurate pollution tracking, improved weather forecasting, safer and more efficient ship routing, and more accurate ocean temperature and current forecasting. The Laboratory's work sets the stage for future forecasts that will be accurate for weeks to months, and perhaps years, in advance.

"NCI and NRL are addressing some of the world's most important and complex scientific problems," said Jim Rottsolk, chief executive officer of Cray Inc. "We are proud to provide the high-end supercomputers required to solve these problems for the first time."

Founded in 1988, the Computerworld Smithsonian Program searches for and recognizes individuals and organizations who have demonstrated vision and leadership as they strive to use information technology to benefit society. Each year, the Computerworld Smithsonian Chairmen's Committee nominates organizations that use information technology to improve society across 10 categories: Business and Related Services; Education and Academia; Environment, Energy and Agriculture; Finance, Insurance and Real Estate; Government and Non-Profit Organizations; Manufacturing; Media, Arts and Entertainment; Medicine; Science; and Transportation.

This year's Collection has become part of the Permanent Research Collection on Information Technology at the Smithsonian's National Museum of American History. More information about the 2000 Collection is available at the Computerworld Smithsonian Program's Web site, http://www.cwsmithsonian.org.
