SGI to Supply NASA's Next Major Supercomputer

More than 20,000 Intel Xeon Processor Cores to Give Scientists Unprecedented Resource for New Generation of Research and Engineering

SUNNYVALE, Calif., May 6 -- NASA has chosen SGI (NASDAQ:SGIC) to supply its next major supercomputer, a 20,480-core SGI(R) Altix(R) ICE system, after a competitive evaluation the space agency launched last year.

The new SGI(R) system, to be installed this summer in the NASA Advanced Supercomputing (NAS) facility at Ames Research Center in Silicon Valley, presents vast new opportunities for scientists and engineers who are attempting to tackle some of the largest and most complex problems in history. The supercomputer will be capable of generating 245 trillion operations per second (Teraflops).

NASA's plan to resume manned missions to the moon -- and eventually manned exploration of Mars -- is one of the chief reasons for securing a new, exceptionally powerful computing resource. In addition to space exploration, the new SGI supercomputer will support NASA's aeronautics, science and space operations initiatives.

Powered by the latest Quad-Core Intel(R) Xeon(R) processors, the new supercomputer will feature more than 20,800 Gigabytes (GB) of system memory -- equal to the memory found in 10,000 of today's desktop PCs. NASA also will deploy a next-generation SGI(R) InfiniteStorage InfiniBand disk solution capable of storing and managing 450 Terabytes (TB) of data -- an amount five times larger than the entire print collection of the Library of Congress. The installation also includes a 115TB SGI(R) InfiniteStorage NEXIS Network Attached Storage solution.

The system will augment NASA's Columbia supercomputer, an SGI(R) Altix(R) system that, when it was installed in 2004, made history as the most powerful supercomputer in the world. Since then, Columbia has enabled a wide range of breakthroughs, including the preliminary design of a new launch vehicle that someday will carry astronauts back into space, weather models capable of predicting a hurricane's path up to five days before landfall, and a visualization of gravitational waves created by two colliding black holes.

"NASA's four mission directorates face computing challenges of unprecedented complexity, and these challenges present unique, even monumental compute requirements," said Dr. Rupak Biswas, acting chief of the NAS Division. "Just as Columbia has helped NASA achieve breakthroughs that were previously impossible, this new supercomputer will enable NASA to continue tapping the far limits of science and innovation."

"SGI is proud to supply NASA with its next supercomputer -- a system that will allow NASA to maintain its pioneering leadership in supercomputing," said SGI CEO Robert "Bo" Ewald. "This new SGI Altix ICE system will help the agency carry humankind further into space, better understand the future that awaits our planet, and improve the quality of life for people around the world. We are delighted to extend our collaboration with NASA -- a collaboration that began 25 years ago when NASA became SGI's first customer -- as the agency embarks on its most exciting missions yet."

"Every day NASA makes history, forging a new path in the journey to understand the world and its place in the universe," said Diane M. Bryant, vice president of Intel's Digital Enterprise Group and general manager or Server Platforms Group. "Working with SGI, Intel has ensured that our leading-edge processor architectures serve as the essential engine in creating history. It is exciting to imagine the breakthroughs this remarkable new system will enable, and what those discoveries will mean for all of us."

NASA's new Altix ICE system will be built from highly integrated blades enclosed in 40 racks, each equipped with 512 processor cores and 512GB of memory. Energy-smart and space-efficient, the dense, water-cooled SGI Altix ICE system will allow NASA to minimize its impact on the data center -- in terms of space, energy use and cooling costs. Cost savings aren't the only benefit: Compared to a typical server, a 10TFLOP SGI Altix ICE system can reduce carbon dioxide emissions by up to 293 metric tons every year -- the environmental equivalent of pulling 53 passenger vehicles off the road(1).

The new system complements Columbia because it is especially suited to running applications that decompose into chunks that can be distributed across a supercomputer's many compute nodes, and a fast InfiniBand connection between those nodes guarantees high bandwidth and low latencies. Columbia is a shared-memory system, which means it can apply more memory to a single application and is optimized for problems that benefit most from SGI(R) NUMAlink(TM), the lowest latency interconnect in the industry. For this reason, both of NASA's SGI supercomputers may be used for a single project, depending on researchers' needs and application requirements.

When it is installed, NASA's new supercomputer will be one of the largest SGI Altix ICE systems ever deployed, joining the State of New Mexico's Encanto, a 14,336-core SGI Altix ICE system currently ranked as the third most powerful supercomputer in the world. The new NASA system will run Novell SUSE Linux Enterprise Server 10.
