SGI Shatters World Performance Record Company Attains Linear Scalability on 64-Processor Itanium 2-Based System

Running Linux

    INTEL DEVELOPER FORUM, SAN JOSE, Calif., Sept. 9 /PRNewswire-FirstCall/ --
 At the Fall 2002 Intel Developers' Forum, SGI (NYSE:   SGI) today announced a
 breakthrough in advancing high-performance, scalable systems based on the
 Intel(R) Itanium(R) 2 processor and the Linux(R) operating system for high-end
 technical application users.
     SGI has attained linear scalability on a 64-processor Itanium 2-based
 system and world-record results among microprocessor-based systems on the
 STREAM Triad benchmark, which tests memory bandwidth performance.
 Demonstrating linear scalability from 2 to 64 processors, the Itanium 2-based
 prototype system from SGI exceeded 120GB per second on a single system image.
 This result, derived from initial internal testing, marks a significant
 milestone for the industry:  Early Itanium 2-based SGI(R) systems built on the
 innovative SGI(R) NUMAflex(TM) shared-memory architecture, have proven that
 Linux can scale well beyond the perceived limitation of eight processors in a
 single system image.
     Additionally, results show that the upcoming Itanium 2-based SGI system
 has not only outperformed the IBM(R) eServer p690 and Sun Microsystems Sun
 Fire(TM) 15K high-end microprocessor-based systems, it has also surpassed
 memory bandwidth performance on the CRAY C90(TM), the CRAY SV1(TM) and the
 Fujitsu VPP5000 CMOS vector-based supercomputers.
     SGI recently announced its expanded business strategy in which it will
 incorporate systems based on the Itanium processor family running Linux into
 its established line of high-performance computing systems. By utilizing Intel
 components within its NUMAflex modular architecture, SGI positions itself as
 the lead source for scalable Linux systems.
     Early next year, SGI will release its fully optimized Itanium 2-based
 systems and its final STREAM benchmark results. The new Itanium 2-based SGI
 systems will enable maximum performance and scalability for a breadth of
 technical applications and will be fully compatible with two future Itanium
 processor family products (code-named "Madison" and "Montecito") to offer an
 unmatched investment protection.
     "With its rich legacy in technical computing, SGI is well positioned to
 speed the adoption of the Itanium 2 processor in scalable high-performance
 environments," said Mike Fister, senior vice president and general manager,
 Enterprise Platforms Group, Intel. "We are delighted to see an Itanium 2-based
 system achieve such high efficiency in scaling Linux to this level, clearly
 demonstrating the benefits of combining the Itanium 2 processor's outstanding
 performance and scalability with SGI's NUMAflex architecture."
     "This accomplishment will turn the heads of those who considered
 clustering a multitude of PCs as an optimal solution for integrating Linux
 into technical computing labs," said Jon "maddog" Hall, president and
 executive director, Linux International.  "For those applications that need to
 scale, SGI has just proven that Linux need not be synonymous with clutter."
     "This accomplishment demonstrates SGI's unique ability to innovate at the
 edge of the performance frontier," said Paul McNamara, vice president,
 Products and Platforms, SGI.  "Our NUMAflex architecture enables us to create
 the world's most scalable shared-memory supercomputers, while delivering the
 rich application environment that is developing around the Intel Itanium line
 of processors and the Linux operating system."
     Expanded Strategy
     Under its new business strategy, SGI will expand its product and service
 offerings by adding its core technology into systems running the MIPS(R)
 processor and the IRIX(R) operating system-and soon, its Itanium 2-based
 systems running the Linux operating system. NUMAflex will remain the
 foundation of all SGI systems. Through its experience and expertise in high-
 performance computing, SGI will offer customers of the highest quality 64-bit
 operating environments.
     About STREAM
     STREAM is a highly regarded performance metric that measures the
 sustainable memory bandwidth, or flow, of a computing system. High-performance
 computing codes require a balance between the processor and memory subsystem
 to maintain a constant flow of data.
