LOS ALAMOS SELECTS CRAY RESEARCH SYSTEMS FOR
SCIENCE-BASED STOCKPILE STEWARDSHIP MISSION

EAGAN, Minn., December 22, 1994 -- The Department of
Energy's Los Alamos National Laboratory (Los Alamos) has
selected high-performance computing systems from Cray
Research, Inc. (NYSE:CYR) for the laboratory's mission to ensure
the safety and reliability of the U.S. nuclear weapons stockpile,
Cray Research announced today.

As a result of the competitive procurement win, a 256-
processor CRAY T3D massively parallel processing (MPP)
system and an interim 4-processor CRAY Y-MP supercomputer
system are scheduled to be installed by year-end 1994 at Los
Alamos.  In 1995, Los Alamos expects to upgrade the CRAY T3D
system to 512 processors, and to replace the CRAY Y-MP
system with a four-processor version of Cray Research's next-
generation parallel vector supercomputer system, code-named
Triton, the company said.  Financial terms were not disclosed.

"We're pleased that our systems won this intensive
competition for a new usage at one of Cray Research's most
valued, long-time customers," said Cray Research president
and chief operating officer Robert H. Ewald.  The systems will
be used to run large, complex 3-D computer simulations as an
alternative to live safety, reliability and performance testing
of the weapons stockpile.  

"We are excited about this major addition to our suite of
production computers that affirms our leadership position in
the application of parallel computers to crucial national
problems," said Dr. Hassan Dayem, director of Los Alamos'
Computing, Information and Communications division.

According to Dr. John Cerutti, project leader for 3-D code
development in Los Alamos' Applied Theoretical Physics
division, the Cray Research systems also will be used to speed
progress on various defense-related programs at the
laboratory.  "We expect to simulate much larger problems in
significantly less time than on our current MPP systems."  

This will be the second CRAY T3D system at Los Alamos, Ewald
said.  Earlier this year, a 128-processor system was installed
at Los Alamos' Computational Testbed for Industry as part of a
$52 million, cost-shared technology transfer agreement under
the DOE's Industrial Computing Initiative.  This system was
later upgraded to 256 processors to support the DOE's global
climate modeling "grand challenge" program. 
 
Los Alamos National Laboratory (Los Alamos, N. Mex.) is a
multidisciplinary research organization that applies science
and technology to problems of national security ranging from
defense to energy research.  It is operated by the University of
California for the U.S. Department of Energy.

Cray Research provides the leading supercomputing tools and
services to help solve customers' most challenging problems.
