CRAY RESEARCH UNVEILS SMALLER VERSIONS
 OF INDUSTRY-LEADING C90 SUPERCOMPUTER SYSTEM
 
 Expanded Series Strengthens Company's Mid-Range Product
 Line
 
 EAGAN, Minn., March 23, 1993 -- Starting today, the world's
 most powerful general-purpose supercomputer system, the
 16-processor CRAY C916 (formerly CRAY Y-MP C90), will
 also be available in smaller, lower-priced versions.
 
 Lester T. Davis, chief operating officer of Cray Research
 (NYSE:CYR), said that along with the strong-selling
 16-processor system, introduced in Nov. 1991 at a list
 price of $30.5 million, the company is now offering versions
 with from one to eight processors, at list prices starting at
 $3.25 million in the U.S.  The systems unveiled today
 strengthen the company's mid-range CRAY Y-MP product
 line. Cray Research will also continue to manufacture CRAY
 Y-MP systems to accommodate the sub-$3 million price
 point, Davis said.
 
 He said the CRAY C916 system's industry-leading
 performance created strong customer demand for smaller
 versions of the product. Cray Research has already booked
 five orders for the smaller systems, and is in active
 discussions with more than a dozen additional prospects
 worldwide, he said.
 
 All the C90-series systems feature the newest, fastest
 memory technology available -- four-megabit SRAM (static
 random access memory).  As a result, the CRAY C916
 system is now available with up to one gigaword (one
 billion words) of central memory, the largest high-speed
 memory on any supercomputer today and four times this
 system's previous memory capacity. The smaller systems
 in the new series are offered with up to twice the memory
 capacity of their counterparts in the earlier CRAY Y-MP line.
 Larger memory makes it possible to tackle larger problems,
 or to solve existing problems faster.
 
 "In 1992, the CRAY C916's first year in the market, we had
 to boost production goals to keep pace with orders," said
 Davis. "Our order book for this system is also getting full
 for 1993." To date, he said, the company has received 16
 orders for its top-of-the-line supercomputer and has
 shipped 11 of the systems to government, academic, and
 commercial customers. Among these customers is Ford
 Motor Co., the first commercial organization to install the
 CRAY C916 system.
 
 The expanded C90 product series now includes:
 
 *The CRAY C92A supercomputer system, an air-cooled
 system available with one or two processors, at list prices
 starting at $3.25 million in the U.S. Because the system
 requires no special cooling arrangements, no motor
 generator set, and operates on standard 50 hertz and 60
 hertz commercial electrical power, it can be installed
 virtually anywhere, including on ships and at remote
 processing sites.
 
 *The CRAY C94A system, an air-cooled system available
 with two to four processors and with the same power and
 cooling features as the CRAY C92A system.
 
 *The CRAY C94 system, a liquid-cooled supercomputer
 offered with two to four processors.
 
 *The CRAY C98 system, a liquid-cooled system offered with
 four to eight processors.
 
 *The CRAY C916 system, also liquid-cooled, has been
 expanded and is now available with eight to 16 processors
 and with up to one gigaword (billion words) of real memory.
 
 More than 600 leading software applications currently
 available on the CRAY C916 and CRAY Y-MP systems will run
 without modification on the new series of systems, said
 Sara Graffunder, Cray Research director of applications.
 
 "The C90 series is the most advanced, usable
 high-performance computing technology available today,"
 Graffunder said.
 
 The new CRAY C90-series systems feature the same
 one-gigaflops (billion floating point operations per second)
 CPU as the original CRAY C916 system, which, when fully
 configured, has a peak system performance of 16 gigaflops.
 On a key structural analysis code -- ANSYS from Swanson
 Analysis Systems, Inc. -- the CRAY C916 system has
 achieved sustained single-job performance of 5.9 gigaflops
 and, when running two jobs simultaneously, exceeds seven
 gigaflops, Graffunder noted. Structural analysis codes are
 highly complex and I/O (input/output) intensive.
 
 In addition, 15 well-known applications programs now
 operate at sustained speeds of six to 11 gigaflops on the
 CRAY C916 system, she said. By comparison, the highest
 sustained performance for any code by a current massively
 parallel processing (MPP) system in the 1992
 IEEE-sponsored Gordon Bell Prize competition was 5.4
 gigaflops.
 
 In four major comparison studies (NASA Ames Research
 Center, Los Alamos National Laboratory, San Diego
 Supercomputer Center, Minnesota Supercomputer Center),
 CRAY C90 or CRAY Y-MP systems outperformed current MPP
 systems. In the first two tests, the current MPP systems
 were able to sustain only two to eight percent of their
 stated peak performance, versus 50 percent or more in some
 cases for the Cray Research systems.
 
 MPP Ready
 
 The CRAY T3D system, Cray Research's first MPP system
 due out later this year, will closely couple microprocessor
 technology with the company's parallel vector
 supercomputer systems, including any of the CRAY C90
 series systems. All CRAY C90 systems feature the
 established modular Model E I/O subsystem enabling the
 systems to work in conjunction with the CRAY T3D system.
 Cray Research expects the CRAY T3D system to outperform
 competing MPP systems.
 
 Cray Research creates the most powerful, highest-quality
 computational tools for solving the world's most
 challenging scientific and industrial problems.
