SEATTLE, WA, Jun 20, 2006 (MARKET WIRE via COMTEX News Network) —
Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that it
will offer the QLogic® PathScale® Compiler Suite on its Cray XT3™
supercomputer. Users who need the features and performance of the PathScale
Compiler Suite, including organizations that are already running the compiler
suite on other platforms, will be able to obtain the software directly from
Cray for their AMD Opteron™-based Cray XT3 systems.

"We have seen increasing demand for QLogic PathScale compilers from
our growing Cray XT3 user base and are moving to meet that need," said
Jan Silverman, senior vice president, corporate strategy and business
development for Cray. "Cray supercomputers support performance demanding
users running multiple applications. By offering a choice of compilers in our
products, we are giving customers powerful tools to help them be more
productive and enabling them to fully exploit system performance and
portability of applications."

"A Cray XT3 supercomputer equipped with dual-core AMD Opteron
processors brings tremendous computational power to high-performance computing
applications," said Len Rosenthal, vice president of marketing for the
QLogic Systems Interconnect Group. "We are excited to be able to further
enhance application performance on these systems with our powerful 64-bit
PathScale compilers, and to collaborate with Cray on providing scientists and
engineers with tools that can efficiently handle their most challenging
computational tasks."

About QLogic's PathScale Compiler Suite

The award-winning PathScale Compiler Suite from QLogic offers
high-performance C, C++ and Fortran 95 compilers for 64-bit Linux®-based
computer systems. The compiler suite offers sophisticated optimization
infrastructures for both AMD64 and Intel EM64T architectures. Taking advantage
of the performance features of AMD64 processors, PathScale compilers help
enhance application performance for AMD Opteron-based systems such as the Cray
XT3 supercomputer. Utilizing AMD Opteron's advanced processor features --
including complex addressing modes, large register sets, more efficient
parameter passing and SSE2 support -- the PathScale Compiler Suite generates
highly efficient execution code.

About the Cray XT3 Supercomputer

The Cray XT3 supercomputer is the third-generation MPP system from Cray.
Purpose-built to deliver exceptional sustained application performance for
challenging scientific and engineering problems, the Cray XT3 system has set
new performance records for systems equipped with standard-based processors.
The supercomputer's high-speed 3D torus interconnect, advanced MPP operating
system and high-speed global input/output make it possible for users to scale
applications from 200 to more than 30,000 processors without performance loss.
The system's scalable processing element uses x86 64-bit AMD Opteron single or
dual-core processors that employ HyperTransport™ technology to increase
bandwidth and reduce latency. The Cray XT3 supercomputer was named 2005
Product of the Year by Scientific Computing & Instrumentation. Go to www.cray.com/products/CrayXT3 for more information.
