DUPONT ORDERS CRAY C94 SUPERCOMPUTER SYSTEM

EAGAN, Minn., Nov. 11, 1993 -- E.I. du Pont de Nemours & Co.
(DuPont), Wilmington, Del., has ordered a CRAY C94
supercomputer system, Cray Research (NYSE:CYR) announced
today.  The system is scheduled to be installed at the DuPont
Experimental Station in Wilmington in the first quarter of
1994, replacing a four processor CRAY Y-MP system.  Terms
were not disclosed.

DuPont will use the CRAY C94 supercomputer in four primary
areas: computational chemistry, process (manufacturing)
simulation, structural analysis, and environmental modeling. 
DuPont currently runs these applications on the CRAY Y-MP
system to develop new products, design new chemical plants
and model the environment impacts of DuPont's products. 

The CRAY C94 system, Cray Research's four-processor model
in the new CRAY C90 series, is the fourth generation of Cray
Research systems ordered by Dupont.  "Dupont was one of the
first commercial firms to use supercomputers, starting with
the CRAY 1 system," said Dr. Robert Eades, Cray Research
director of chemical industry marketing.  

"The CRAY Y-MP has been an important tool in DuPont's
development of appropriate alternatives to CFCs
(chlorofluorocarbons)," said Dr. Alexander MacLachlan, senior
vice president, DuPont research and development.  "The
supercomputer was used to identify the problems with CFCs,
to help develop potential alternatives using computational
chemistry, and to develop manufacturing processes and
measure the environmental impacts of alternative CFC
products."

"We view Cray systems as tools for solving real business
problems," said Dr. David Dixon, a research leader in DuPont's
central research and development division.  "Doing simulations
on the CRAY Y-MP has helped us to develop new,
environmentally safer products, with significant 
cost avoidance."  According to Dixon, the new CRAY C94
system will allow DuPont to work with larger, more complex
molecular and atomic systems. 

"DuPont is an industry leader in applying supercomputing to
many areas of its bottom line business," said Eades.  "DuPont's
development of alternatives to CFCs is just one example of the
company's breakthrough environmental solutions.  We are
pleased to continue our relationship with DuPont by providing
the new CRAY C94 system to support DuPont's work."

Cray Research creates the most powerful, highest-quality
computational tools for solving the world's most challenging
industrial and scientific problems.
