CRAY RESEARCH JOINS PARTNERSHIP FOR THE AMERICA'S CUP TECHNOLOGY

 CRAY RESEARCH JOINS PARTNERSHIP FOR THE AMERICA'S CUP TECHNOLOGY
 Firm Provides Supercomputing Time, Financial Support
 to Help U.S. In '92 America's Cup Defense
 EAGAN, Minn., March 3 /PRNewswire/ -- Cray Research, Inc. (NYSE: CYR), has become a corporate partner of the Partnership for America's Cup Technology (PACT), a joint effort to develop basic technology to aid American syndicates in the 1992 America's Cup defense, the Eagan-based supercomputer manufacturer announced today. Other PACT corporate partners include Boeing Corporation, IBM, and Science Applications International Corporation (SAIC), the founding organization of PACT.
 "To all countries involved, the America's Cup competition has become an issue of national pride," said John Rollwagen, Cray Research chairman and chief executive officer. "PACT, with the support of leading-edge U.S. corporations, is an excellent example of American industry working together and investing in technologies for today, as well as the future."
 Cray Research has participated in America's Cup yacht design in the past. Computations for the revolutionary design of the Stars and Stripes, the 1987 America's Cup winner sailed by Dennis Conner, were performed on a Cray Research supercomputer.
 In support of the 1992 competition, last August the company loaned equipment to provide additional capabilities in Boeing Computer Services' CRAY Y-MP system. This additional capability is devoted exclusively to PACT research through the '92 final races, held this May, and is being used to develop and advance computational fluid dynamics (CFD) codes for use in yacht
design. PACT, in conjunction with a team of researchers at Boeing, uses the Cray Research-loaned CPUs to adapt CFD codes for application to the design of the new International
America's Cup Class (IACC) sailboats. The Boeing team's specific focus is keel design, as optimal keel design is integral to the speed of the boat.
 "Water behaves very much like air," said Ed Tinoco, associate technical fellow and technical leader of the Boeing team supporting PACT. "As such, we have found that using CFD analysis -- much of which requires the power of a Cray Research supercomputer -- allows yacht designers to approach their design problems similar to how we approach an aircraft design problem."
 Tinoco noted that the payoffs in applying this technology can be significant. "If we determine a design that allows for a one percent reduction in drag, this can amount to an annual fuel-cost savings of tens of thousands of dollars per aircraft for an airline company. And a one percent reduction in drag for the America's Cup is clearly the difference between victory and defeat."
 Two additional teams -- one at South Bay Simulations, Babylon, NY, and another at SAIC in San Diego -- are conducting similar CFD code work using
donated CRAY Y-MP supercomputing time from Cray Research. These two teams will focus on calculating boat hull drag.
 The CFD codes being researched by the teams were originally developed by the commercial aerospace industry and NASA, and have been used on Cray Research systems for aerospace applications for the past 11 years. Ultimately, these CFD codes will be used to calculate the various components of ship design, including drag of the boat and keel, and to calculate the lift of the keel, bulb, and rudder.
 PACT research is of particular interest to Cray Research because it advances the use of CFD codes on supercomputers, which ultimately benefits the company's customers in the aerospace, automotive, chemical, manufacturing, petroleum, and other industries. Cray Research has also contributed financial support for tank and wind tunnel physical tests associated with software code validation, which is essential for yacht designers to have confidence that the CFD codes are applicable to yacht design.
 As in other industries that use supercomputing, the key advantage for competitive yacht design is that it is possible to simulate a variety of designs for each yacht component, and then determine how each affects the speed
and performance of the entire structure. Using a supercomputer allows designers to distinguish the good design ideas from not-so-good ideas prior to building a prototype and physically testing the design.
 "The application of supercomputing to America's Cup boat design is a true competitive advantage," said John Marshall, general manager of PACT and 1986-87 design project manager for Stars and Stripes.
 "Since 1987, the role of computer modeling to design sailing yachts has increased significantly, and the reason is the access to supercomputers," said
Marshall. "A designer who has access to a supercomputer will push theoretical developments to the limit. Cray Research's participation with PACT has helped the program tremendously; the donation of supercomputer time allows our technologists to set their limits high because they know that if they develop a large and complex model they will have access to a powerful Cray Research system that can calculate the problem. Access to high-powered computing goes hand-in- hand with pushing new applications and ideas."
 "We at Cray Research are pleased that our computational tools can be applied to this interesting and high-profile application," said Rollwagen. "There seems to be no limit to the use of our computational power. In fact, recently we worked with MacGregor Golf Company to design its new titanium metal driver on a CRAY Y-MP, and CFD experts used one of our systems to do an aerodynamic analysis of an Olympic skier in flight to determine the best jumping position."
 Cray Research creates the most powerful, highest-quality computational tools for solving the world's most challenging scientific and industrial problems.
