SGI TO SHOWCASE 128 PROCESSOR ALTIX SYSTEM AT SC2003: ONE OF THE MOST
POWERFUL SINGLE LINUX SYSTEMS

Industry Luminaries Speak on SGI’s Stage; Company Also Features Latest in
Centralized Storage and Visualization Technology


SC2003 Conference and Phoenix, AZ - Nov 17, 2003— SGI today announced from
the SC2003 conference that the company will feature its powerful SGI®
AltixTM 3000 family of Linux® OS-based supercomputers. SC2003, the
international conference on high-performance computing and networking, is
held this year at the Phoenix Civic Plaza Conventional Center, Nov. 17-20.
SGI will publicly display for the first time an Altix supercomputer powered
by 128 Intel® Itanium® 2 processors utilizing the company’s scalable
NUMAflexTM shared memory architecture. In its first year, customers across
the globe have adopted this new breed of supercomputer demonstrating the
strong desire for more open and scalable computing options.

“We’ve had an amazing year and made tremendous strides since the last
Supercomputing industry conference,” said Bob Bishop, chairman and CEO,
Silicon Graphics. “SGI has introduced significant advancements across all
product lines as a continuation of its total focus on the high-performance
technical marketplace. Most of all, we are very proud of the tremendous
achievements our customers have made using SGI technology across so many
critical areas of bioinformatics, climate modeling, energy research,
manufacturing and national defense. SGI is clearly demonstrating its HPC
industry leadership.”

Customers, business partners and industry experts will take the stage in the
Silicon Graphics booth (Number 835) before a 20-foot SGI® Reality Center®
presentation theatre to showcase the impact to their work and the
record-breaking accomplishments they have achieved by using the company’s

Along with the SGI Altix 3000 family of scalable Linux systems, an extensive
array of new centralized storage and visualization products is also being
demonstrated at the SGI booth. These include the SGI® InfiniteStorage
solutions, Silicon Graphics® Onyx4™ UltimateVision™ visualization system,
Silicon Graphics® Tezro™ visual workstation, SGI® Origin® family of servers,
and demonstrations of Visual Area Networking and collaborative Grid
computing.

SGI Altix Takes Center Stage at SC2003

"The shared-memory architecture of the SGI Altix system allows SGI customers
to take the fullest advantage of the Intel Itanium 2 processor," said
Richard Dracott, director of marketing, Enterprise Platforms Group, Intel.
"Together, SGI and Intel are providing HPC users with a supercomputing-class
system that scales reliably to hundreds of processors with industry-standard
components and a Linux operating environment."

Once again breaking the perceived limits of scalability, the Altix system
encompasses a record 128 processors and terabyte of memory within a single
instance of the Linux operating environment and up to 512 processors and 4TB
of memory in a supercluster configuration. Such capabilities leverage the
built-in SGI NUMAlink™ interconnect fabric, delivering data across nodes up
to 200 times faster than conventional clustering interconnects. The broad
acceptance of Altix is solid evidence of a growing appetite for scalable,
shared-memory systems capable of achieving industry-leading performance with
Itanium 2 processors.

SGI attributes much of the success of the Altix line to its NUMAflex shared
memory architecture in which all the processors in the computer share the
same memory. This is distinct from older computer architectures and clusters
where every processor has its own associated memory. The main advantage of
shared memory is not having to move data from one memory location to
another, which results in faster processing and easier programming. Simply
put, utilizing the NUMAflex share memory model saves users tremendous time
and effort much like doing a month's worth of shopping at a “super” store or
mall is more efficient than running all over town to different stores.

Among the awards presented to the Altix system this year, most recently the
system earned “Most Innovative Overall HPC Technology” in the 2003 HPCwire
Innovation Awards and the Linux Journal  “Readers' Choice Awards.” The Altix
line was also prominently featured on the 22nd Top 500 List of the world’s
fastest supercomputers.

Origin Systems for Defense and Homeland Security

Also built upon the NUMAflex architecture, SGI will demonstrate the Origin®
350 system running as a satellite ground station with data ingest, compute
and storage in a single rack. SGI pairs the high reliability and massive I/O
capability of the Origin server family with the IRIX® operating system for
an unstoppable combination for the most demanding applications in areas
including government and homeland security.

InfiniteStorage Puts SGI on the Map

With InfiniteStorage, SGI is changing the rules in network storage by
delivering hardware and software solutions specifically developed for the
unique and demanding needs of data-intensive enterprises. Customers include
Wright-Patterson Air Force Base in Dayton, OH, which acquired in the spring
of 2003 a staggering 40TB of SGI InfiniteStorage to support a 2,048
processor SGI® Origin® 3900 system, the largest ever built.

Live on the show floor and networked to sites over 6,200 miles away, SGI
will demonstrate the unique capabilities of InfiniteStorage solutions. Using
technology from YottaYotta and SGI® InfiniteStorage Shared Filesystem CXFS™
in a SAN over a wide area network, the demonstration will convey the
tremendous cost and time savings from sharing data over a distributed
network—without having to duplicate data or the storage infrastructure.

Shipping for four years, CXFS is a mature shared filesystem that delivers
instant, no-copy data sharing and includes support for a wide range of
leading operating environments—enabling users and applications to share data
concurrently over a SAN without replicating files. CXFS now supports Linux
and IBM® AIX® operating environments in addition to current support for
IRIX®, Solaris™ and Windows® platforms.

SGI will also demonstrate how to automate data movement based on the
customer's workflow across multiple storage technologies in a multi-tier
storage hierarchy. On the new SGI InfiniteStorage TP9300S Serial ATA storage
system, SGI's Data Migration Facility will migrate data in the filesystem
from Fibre Channel disk to the TP9300S SATA disk and then to multiple tape
formats in a tape library.

New Perspectives on Visualization

Delivering eight times the power at a fifth of the price of previous
systems, SGI’s fourth generation Onyx4 UltimateVision system, based on a new
graphics architecture provides unparalleled scalability and performance in a
compact affordable solution. Demonstrations will verify the power of a
visualization system that marries a supercomputer to industry-standard
graphics cards. SGI continues its mission to help advance technology that
enables users view data from the most effective and realistic perspectives.
Among demonstrations at the SGI booth will be DDD, Inc. with its new
auto-stereo capability that converts non-stereo applications to stereo
automatically without the use of glasses.

Additionally, live from the show floor SGI’s Visual Area Networking
demonstration features a new level of performance and interactivity that
links organizations and data from disparate sites. These demonstrations,
featuring the new Onyx4 and Tezro systems, bring unprecedented levels of
visualization power and multisite collaboration to individuals and teams.
