SCIENTIFIC'S LINDA SOFTWARE AVAILABLE FOR CRAY
T3D SYSTEM

EAGAN, Minn. and NEW HAVEN, Conn., Nov. 9, 1994 -- SCIENTIFIC
Computing Associates' (SCIENTIFIC) Linda software, a leading
product for parallelizing and running applications on parallel
computers, is now available for the CRAY T3D massively
parallel processing (MPP) system from Cray Research, Inc.
(NYSE:CYR), the companies announced today.

"Working with Cray Research, we have optimized Linda for use
on the CRAY T3D system in both C and Fortran, the most widely
used programming languages for scientific and technical
computing," said Leigh Cagan, SCIENTIFIC's vice president of
marketing and business development.  "This means existing
Linda-based applications can now be run on the Cray system
with little or no modification, and new highly parallel
applications can be efficiently generated for the CRAY T3D
from users' sequential codes."

SCIENTIFIC's Linda is an important addition to the programming
and applications support tools available for the CRAY T3D
system, according to Derek Robb, Cray Research vice president
of marketing.  "Many important production applications have
been parallelized using SCIENTIFIC's Linda, especially for
workstation networks and clusters.  Now these applications
can be moved to the CRAY T3D system when customers need
faster solution times or want to keep the workstation systems
free for less demanding work," he said.  "Users can leverage
their applications investments and realize substantial
speedups with minimal effort." 

Robb said today's announcement supports Cray Research's
effort to make a wide range of programming methods and
applications available for the company's MPP system.  "In its
first full year, the CRAY T3D system has become the
performance and revenue leader in the scientific-technical MPP
market," he said. "Applications availability is the pacing item
for broader market acceptance of MPP systems.  We have
numerous initiatives under way to make leading applications
available first and with unrivaled performance on the CRAY
T3D system."  

Cagan said SCIENTIFIC's Linda software systems enable quick
conversion of sequential codes into portable parallel
applications for a variety of platforms, within the context of
an easy-to-use virtual shared memory.  Linda consists of four
basic commands that users add to codes written in standard
programming languages, such as C or Fortran.  Linda leaves to
the base languages the chores for which such languages were
designed--arithmetic, loop control, procedure calling,
input/output, and so on--and concerns itself solely with
interprocessor communication and control.  Linda thus fully
leverages users' existing investments in software and
programmer skill sets.  As a memory-based model,
SCIENTIFIC's Linda frees users from the often complex details
of explicit interprocessor communications and supports a wide
variety of programming styles.  These unique attributes of
Linda make it easier to visualize, implement and debug parallel
codes--a major advantage, especially for new users with large
production applications, he said.

Founded in 1980, SCIENTIFIC Computing Associates, Inc. is a
leader in the field of software technologies for parallel and
distributed computing.  SCIENTIFIC's Linda, Piranha and
Paradise software products are used in production computing
environments throughout such industries as finance and
insurance, pharmaceuticals, semiconductors, petroleum,
automotive and aerospace.  Based in New Haven, Connecticut,
SCIENTIFIC sells and supports its products on a direct basis
and through select OEMs, VARs and independent distributors in
the U.S. and abroad.  

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