CRAY RESEARCH TO OFFER HPF ACROSS ALL PARALLEL
SYSTEMS; COMPANY CHOOSES THE PORTLAND GROUP'S
HPF PRODUCT

SAN DIEGO, Dec. 5, 1995 -- Cray Research, Inc. (NYSE:CYR) and
The Portland Group, Inc. (PGI) announced today at
Supercomputing '95 that they have signed a letter of intent for
Cray to offer PGI's pghpf High Performance Fortran (HPF)
compiler on all of its computing systems, including the
recently announced CRAY T3E(tm) scalable parallel system.

"We are looking forward to offering our customers and
prospects an HPF product," said Mike Booth, vice president of
Cray's software division.  "Our corporate strategy is to
continue to leverage leading technologies from other
companies, while applying Cray core competencies in parallel
computing.  We were seeing interest from our customers in HPF
and conducted a very thorough technical evaluation.  PGI's
product clearly emerged as the HPF of choice and we believe
that this product can provide ease-of-use and robustness to
our users wanting HPF."

HPF extends ISO/ANSI Fortran 90 to support implicit data
parallel programming.  It provides all the power of Fortran 90,
including array syntax, array intrinsics, and dynamic storage
allocation.  In addition, HPF directives support the distribution
of data among processors, the alignment of data objects to one
another, and assertion of the independence of parallel loop
iterations.  HPF is the de facto standard for implicit parallel
programming for shared- and distributed-memory systems.

PGI's pghpf product allows users to run applications unchanged
on Cray(R) systems ranging from the CRAY J90(tm) low-cost
compact supercomputer to the company's high-end CRAY
T90(tm) system and the company's scalable parallel systems,
the current CRAY T3D(tm) and the new CRAY T3E(tm) systems. 
The pghpf compiler has already proven effective on several
large applications in the areas of fluid flow, wave simulation,
particle simulation, and 3D reservoir modeling.

"This is a real milestone for HPF as well as PGI," said Douglas
Miles, director of marketing at PGI.  "We are pleased to see
Cray Research offer HPF on its systems and that our product,
after rigorous analysis, emerged as the leader for Cray.  We
look forward to seeing our product move into Cray's customer
base and to serving the High Performance Fortran needs of
these users.  The fact that Cray, a leader in high-performance
parallel computing, has selected pghpf is a strong vote of
confidence in our HPF technology."

The PGI HPF compiler is currently available through PGI on the
CRAY CS6400 symmetric multi-processing server and the CRAY
T3D system.  Users of pghpf on the CRAY T3D system can port
and develop HPF applications that will run unchanged on the
soon-to-be-available CRAY T3E, the most scalable
supercomputer in the world with tens to thousands of
processors.  Cray said it expects to directly offer pghpf on
these systems and on Cray's parallel vector supercomputers
beginning in early 1996.  pghpf will be available on the CRAY
T3E when volume shipments begin next year.

PGI is offering product demonstrations of pghpf and related
HPF program development tools in its booth (#911) at
Supercomputing '95.

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

PGI is a leading independent vendor of software tools for
parallel computing.  PGI provides high-performance,
retargetable, production quality compilers and software
development tools to the high performance computing industry.
