World's Most Powerful CRAY at Pittsburgh

PITTSBURGH -- The Pittsburgh Supercomputing Center has added 256 high-performance processors to its existing 256-processor CRAY T3E, and the performance of the resulting 512-processor system exceeds that of any other currently installed Cray.

Researchers will use all 512 processors of the expanded system simultaneously to attack "grand challenge" problems, including:

This expanded capability, said PSC scientific directors Michael Levine and Ralph Roskies, reflects the center's record of providing the earliest, most powerful facilities to computational researchers nationwide. "The additional 256 processors is part of a plan," they said, "begun in March 1996 when we acquired the world's first CRAY T3E, to provide a 512-processor system. It reflects our longstanding tradition of pushing the limits of what's possible to provide the best capabilities to the U.S. computational research community."

A high proportion of the research -- 25 percent -- carried out on PSC's CRAY T3D, predecessor to the CRAY T3E, runs simultaneously on all 512 processors, a statistic that reflects PSC's expertise in helping researchers derive the maximum benefit from, and most cost-efficient use of, scientific computing resources.

The new high-performance processors have a peak speed 1.5 times faster than the original CRAY T3E processors, and the upgraded 512-processor system is capable of 384 billion computations per second (gigaflops). This is 70 times more processing power than every person on Earth holding a calculator and doing one calculation per second.

More information, including graphics, about the above research projects and others is available on World Wide Web at http://www.psc.edu/science.

The Pittsburgh Supercomputing Center, a joint effort of Carnegie Mellon University and the University of Pittsburgh together with Westinghouse Electric Corp., was established in 1986 by a grant from the National Science Foundation, with support from the Commonwealth of Pennsylvania.
