CRAY RESEARCH INTRODUCES NEW GENERATION OF
LARGE-MEMORY SUPERCOMPUTER SYSTEMS

CRAY C90D Systems Efficiently Tackle Largest
Problems, Handle Heavy Multiuser Workloads 

EAGAN, Minn., April 18, 1994 -- Cray Research, Inc. (NYSE:CYR)
today introduced the CRAY C90D series, a new generation of
large-memory supercomputer systems designed to solve
extremely large scientific and engineering research problems
and handle heavy multiuser workloads, the company said.

The new systems combine the company's industry-leading
CRAY C90 supercomputer technology with the latest 16-
megabit DRAM memory chips to provide up to two billion words
(gigawords) of real main memory and new problem-solving
capabilities, according to Robert Ewald, Cray Research chief
operating officer, supercomputer operations.

The series includes three models: the air-cooled CRAY C92AD
system, providing up to 2 billion calculations per second
(gigaflops) of peak performance and 512 million words of
central memory; and the liquid-cooled CRAY C94D system (up
to 4 billion calculations per second, 1 billion words of
memory) and CRAY C98D system (up to 8 billion calculations
per second, 2 billion words of memory).   Pricing for the
systems is from $3.5 million in the U.S.  Availabilty is
immediate.

A CRAY C92AD system, representing the first order for the
new series, was recently installed in the Central Research
Facility of chemical-industry giant Bayer AG, Leverkusen,
Germany.  Bayer will use the system to solve large,
computationally intense problems in chemical process
simulation, such as planning and laying out production
facilities, and to optimize plant operations for safety,
environmental factors and cost-effectiveness, he said.  This
early order was announced in November, 1993.    Ewald said
Cray Research expects to announce additional orders for the
new series in the near future.

For important classes of very large programs, he said, Cray
Research's large-memory systems can substantially speed up
solution times and increase R&D productivity, by making it
possible to run the problems in one piece.  "Problems too large
for a system's central memory have to be broken down and run
in smaller pieces, resulting in cumbersome programming work
and slower solutions." 

Customer needs addressed by the new systems include: large
computation fluid dynamics (CFD) and structural analysis
applications in the automotive and aerospace industries;
chemical process simulation and molecular modeling of large
chemical structures in the chemistry industry; large seismic
processing and reservoir simulation models in the petroleum
industry; large-scale environmental and long-range weather
modeling in those industries; and large multiuser, interactive
workloads in all industries.

The CRAY C90D series runs UNICOS, Cray Research's industry-
leading UNIX implementation, and support the company's full
library of more than 600 leading software applications for
nearly every scientific and engineering discipline.  In addition,
he said, the new systems can be coupled with the CRAY T3D
massively parallel processing (MPP) system to address
applications that are, in part or whole, highly parallel in
nature.

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