In First Three Weeks of Operation, Applications are Running in Parallel Mode on New Cray System

EAGAN, Minn., April 17, 1996 -- The first CRAY T3E scalable parallel system has been installed at the Pittsburgh Supercomputing Center (PSC) and is already running parallel applications, Cray Research announced today.

Although Cray installed this early-access system only three weeks ago, six applications are now running in parallel mode, said PSC officials, and a number of additional applications are targeted for near-term deployment. PSC scientific co-director Michael Levine said that all applications running to date on the new system have produced correct results and that PSC experts have verified hardware and software stability with repeated long overnight runs.

Applications selected for early migration to the CRAY T3E system include several developed by PSC staff and users, as well as frequently used off-the-shelf packages ported and optimized for scalable parallel computing under PSC's Parallel Applications Technology Program partnership with Cray. Applications already running include major quantum chemistry and biomedical applications (CHARMM, GAMESS and AMBER). Others to be added will include software for crystallographic structure determination, properties of advanced materials, leading-edge environmental and finite-element multiphysics codes and Msearch, PSC's parallel genome sequence database searching and alignment package.

Cray said volume shipments of the new supercomputer are slated to begin in third quarter. PSC's system will be upgraded over time and ultimately scale to 512 processors. The center will continue operating its prior-generation CRAY T3D system for production problems and will replace it when the CRAY T3E reaches 512 processors, according to Levine, who made a presentation at an Executive Cray User Group meeting today on the status of the CRAY T3E system and PSC's applications migration progress.

"On behalf of the national scientific community, we at PSC are looking forward to the substantially increased capability of the new CRAY T3E," Levine said. "Its faster processing and communications speeds, coupled with a much larger memory, will enhance our ability to attack leading-edge problems while maintaining our multi-year investment in highly optimized applications programs. This will keep PSC, the NSF supercomputer centers program and American researchers in a world leadership position."

Levine said that over the course of the last three years, PSC users have run a wide-range of industrial and scientific problems on the current CRAY T3D supercomputer, consuming about 4.6 million processing hours. "When we get into full production with the CRAY T3E," said Levine, "we expect scientific productivity to improve by a factor of three to four."

"We are pleased that this early access system is enabling PSC application experts to make such rapid advances in migrating their applications to the CRAY T3E environment," said Robert H. Ewald, Cray Research president and chief operating officer. "The CRAY T3E preserves the macroarchitecture and programming environment of the CRAY T3D. This consistency protects PSC's parallel applications investment and contributes to this exceptional progress by PSC and Cray personnel. This early applications progress will enable the production use of the CRAY T3E at PSC and other customers later this year."

Cray said that it had more than $160 million in advance orders for the CRAY T3E system at year-end 1995.

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. Additional major support comes from the National Institutes of Health. PSC's mission is to develop and make available state-of-the-art high-performance computing for scientific researchers nationwide.

Cray Research provides the leading high-performance computing tools and services to help solve customers' most challenging problems.
