Cray Supercomputers Play Key Role in Designing Boeing 787 Dreamliner
800,000 Simulation Hours Helped Create Design For Highly Successful Commercial Aircraft

SEATTLE, WA, Jul 05, 2007 (MARKET WIRE via COMTEX News Network) -- Global supercomputer leader Cray Inc. (NASDAQ: CRAY) reported today that 800,000 processor hours of computing time on Cray supercomputers went into the design of the highly successful Boeing 787 Dreamliner. (1)

Supercomputer-based modeling and simulation is far more efficient, cost-effective and practical than physical prototyping for testing large numbers of design variables. While physical prototyping is still important for final design validation, Boeing engineers were able to build the 787 Dreamliner after physically testing only 11 wing designs, versus 77 wing designs for the earlier Boeing 767 aircraft.

The Boeing 787 Dreamliner is 20% lighter and produces 20% fewer emissions than similarly sized airplanes, while providing 10% better per-seat costs per mile, according to Boeing.

"Cray is proud that our supercomputers helped Boeing to meet its challenging design goals for the highly successful 787 Dreamliner," said Peter Ungaro, Cray president and CEO. "We're in the business of enabling customers to make important breakthroughs and gain competitive advantage by helping them solve their toughest computing problems."
