LINUXWORLD EXPO BOOTH #1079, SAN FRANCISCO, Aug. 28, 2001 -- SGI Federal, a wholly-owned
subsidiary of SGI (NYSE: SGI), the leading provider of high-performance computing
and visualization solutions for technical and creative users, has teamed up with
Linux cluster computing expert Linux NetworX to win a bid to build three Parallel
Capacity Resource (PCR) Linux cluster computing systems totaling 472 Pentium
4 processors for the National Nuclear Security Administration's Accelerated Strategic
Computing Initiative (ASCI) ongoing computing element. With a theoretical peak
performance of 857 gigaFLOP/s, the largest of the three systems with 252 Pentium
4 processors, named PCR P4A, will be one the fastest Linux clusters ever built.
Linux clustering, an alternative to traditional supercomputing, is a method of 
linking multiple computers together to form a unified and very powerful system. 
By taking advantage of standard computer components, Linux clusters can match 
the performance of supercomputers for a fraction of the cost. 

In its latest effort to boost parallel capacity computing power for ASCI's ongoing 
computing element, Lawrence Livermore National Laboratory (LLNL) will have two 
of the three Linux clusters working on the project, while a third will be used 
as a joint development cluster with Linux NetworX and SGI Federal for open source 
projects.

"The clustering expertise and management tools delivered by Linux NetworX along 
with SGI Federal's project management background and support infrastructure created 
a very powerful and cost-effective solution to meet our requirements," said Dr. 
Mark Seager, LLNL's Asst. Dept. Head for TeraScale Systems. "As LLNL continues 
to add to parallel capacity resources cluster management becomes a more critical 
issue, which is why we required the ICE Boxä management tool from Linux NetworX." 

ASCI is a ten-year program to reach 100-trillion calculations per second by 2005 
that will enable scientists at the national-security laboratory to maintain the 
safety and reliability of the U.S. nuclear stockpile by simulating - in three 
dimensions - the aging and operation of nuclear weapons.
"SGI's experience in delivering high-performance computing solutions has played 
an important role over the years in supporting DOE's ASCI Program to ensure the 
continued safety, reliability and performance of America's nuclear stockpile," 
said Randy Stefano, vice president, professional services, SGI. "Partnered with 
Linux NetworX and Lawrence Livermore National Laboratory, we are set to embark 
on another great engineering milestone by helping to build one of the world's 
fastest Linux clusters while demonstrating the benefits of open-source Linux 
for affordable high-performance computing."      

Linux NetworX designed and built the world's first commercial Linux cluster in 
1997, and has developed cluster management tools to make systems easier to manage. 
In the request for proposal, LLNL required a specific Linux NetworX cluster management 
tool, called ICE Boxä, which is being previewed for the first time at LinuxWorld 
Expo booth #1079. 

"We're excited to be teaming up with SGI Federal to deliver this high-powered 
Linux cluster to ASCI's ongoing computing element at LLNL," said Glen Lowry, 
Linux NetworX President and CEO. "Empowering cluster management tools are proving 
to be an important factor in the wider adoption of Linux clustering into existing 
and new markets."

As a result of this combined win, SGI Federal and Linux NetworX established a 
joint vendor relationship where the two companies will team up to win large cluster 
bids requiring the expertise and cluster management tools of Linux NetworX, and 
the support resources of SGI Federal.
