Sandia and Cray Boost Sandia's "Red Storm" Supercomputer Performance to 125 Teraflops

SEATTLE, WA -- (MARKET WIRE) -- November 15, 2006 --Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that Sandia National Laboratories has upgraded its "Red Storm" supercomputer by boosting performance from 40 teraflops (trillion floating point operations per second) to 125 teraflops, further establishing Red Storm as one of the highest performing supercomputers in the world.

The upgrade included the addition of a fifth row of cabinets and upgrading the entire system with dual-core AMD Opteron™ processors, resulting in a supercomputer with a total of over 25,000 processor cores. Dual-core technology fits two processor cores on a single die, doubling processing capacity with minimal impact on power consumption and heat levels.

Sandia and Cray co-designed Red Storm as part of a contract under the National Nuclear Security Agency's Advanced Simulation & Computing program. The Red Storm design became the basis for the Cray XT3™ massively parallel processor (MPP) supercomputer that has been installed at a number of prestigious supercomputing centers around the world.

"From the inception of Red Storm several years ago, our partnership with Cray has produced highly useful and productive results in a broad range of research fields," said Bill Camp, director of Sandia's Computation, Computers, and Math group. "Red Storm is a key enabler in Sandia's ongoing mission of putting advanced technology to work in the pursuit of global safety, peace and freedom. We are delighted to maintain Red Storm's leadership position with this upgrade and look forward to further leveraging this valuable resource."

"With the success of Red Storm and numerous Cray XT3 systems, our partnership with Sandia has been tremendously productive, enabling scientists and engineers around the globe to conduct breakthrough research," said Cray president and CEO Peter Ungaro. "Sandia's upgrade to 125 teraflops is proof that the architecture was designed and built from the ground up for scalability. This upgrade will preserve Sandia's original Red Storm technology investment while providing them with better than a three-fold increase in processing capability. The real beneficiaries are the scientists and engineers using the system who will see dramatic performance improvements on key applications."
