CRAY RESEARCH MPP SYSTEM INSTALLED AT JAPANESE
NUCLEAR POWER AGENCY

EAGAN, Minn., April 18, 1994 -- A 128-processor CRAY T3D
massively parallel processing (MPP) system from Cray
Research, Inc, (NYSE:CYR) has been installed at the Power
Reactor and Nuclear Fuel Development Corp., Tokyo,  Cray
Research announced today.

The installation, resulting from a Japanese government
procurement awarded to Cray Research in January, 1994,  also
includes a  CRAY Y-MP2E parallel vector supercomputer
system, according to Carl Diem, Cray Research senior vice
president, sales and marketing.  Terms were not disclosed.   

Diem said the two closely linked, air-cooled systems will be
used to analyze the safety, reliability and efficiency of
nuclear power facilities, including nuclear waste disposal
methods, and to explore the applicability of MPP technology to
tasks of this kind.   The heterogeneous CRAY T3D system will
also be made available on a time-shared basis for examination
by various Japanese energy-related organizations, universities
and others, he said.

The newly installed 128-processor CRAY T3D system has 256
million words (two gigabytes) of memory and a peak
performance rating of 19.2 gigaflops (billion calculations per
second), he said.

"We are pleased that our new CRAY T3D system will be used
for this important research by the Power Reactor and Nuclear
Development Corporation and other organizations in Japan,"
said Diem.  "Cray Research is committed to working with this
prestigious new customer to achieve its goals."

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