Cray Inc. Begins Shipping Cray XT3 Massively Parallel Supercomputer Based on Sandia "Red Storm" Design

First Shipment Is To Sandia National Laboratories; Other Initial Customers Include Oak Ridge National Laboratory, Pittsburgh Supercomputing Center

Global supercomputer leader Cray Inc. (Nasdaq:CRAY) today reported that it has begun shipping the Cray XT3(TM) supercomputer, an industry standard massively parallel processing (MPP) system that strongly advances the record-setting scalability and sustained application performance of the renowned Cray T3D(TM) and Cray T3E(TM) systems. U.S. list pricing for the Cray XT3 supercomputer begins at about $2 million.

The first shipment was to the U.S. Department of Energy's (DOE) National Nuclear Security Administration's (NNSA) Sandia National Laboratories (Sandia). The Sandia system was developed and delivered under contract for the Advanced Simulation & Computing (ASC) program. Other initial customers include the Pittsburgh Supercomputing Center and the DOE's Oak Ridge National Laboratory.

The Cray XT3 supercomputer's architecture, co-designed with
Sandia as part of the $90 million "Red Storm" system contract, delivers superior scalable application performance and value across a range of configurations from 200 to 30,000 processors, with peak performance of up to 144 teraflops (trillions of calculations per second).

Cray has shipped a 10-teraflop portion of the
"Red Storm" system to Sandia. When fully installed, "Red Storm" will have over 40 peak teraflops of performance, more than 11,000 AMD Opteron processors, and 240 terabytes of disk storage. The system is expected to be at least seven times more powerful than Sandia's current ASCI Red supercomputer on real-world applications.

That is just the beginning. "Today's Cray XT3 is the first in a series of increasingly powerful scalable Cray products that exploit the Red Storm architecture. The architecture will allow capability to be increased with a simple processor upgrade," said Sandia's Bill Camp, Director of Computers, Computation, Information and Mathematics.

U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), which selected the Cray XT3 system for their National Leadership Class Facility computing initiative, is slated to receive a 20-teraflop Cray XT3 supercomputer, along with a 20-teraflop Cray X1E(TM) vector MPP supercomputer, in 2005. In May 2004, the DOE chose ORNL "to lead a partnership with a goal of building the world's most powerful supercomputer by 2007," according to Energy Secretary Spencer Abraham. ORNL plans to expand to a 100-teraflop Cray system at Oak Ridge in 2006, and to move in 2007 to a system with over 250 peak teraflops and up to 100 sustained teraflops on real-world problems.

Pittsburgh Supercomputing Center (PSC) has signed a contract for a 10-teraflop Cray XT3 supercomputer that can be expanded over time. In a joint statement, PSC scientific directors Michael Levine and Ralph Roskies said, "We are very enthusiastic about making this new and powerful scientific instrument available to National Science Foundation researchers. Remotely using part of the XT3 system which will soon be shipped from Cray to PSC, we have successfully run the Advanced Regional Prediction System (ARPS) from the Center for Analysis and Prediction of Storms, led by Kelvin Droegemeier. Our ability to execute this full application, a comprehensive regional to storm-scale atmospheric modeling/prediction system, as well as our successes with segments of other simulation programs, strongly indicates that it will be a highly productive computational resource."

According to Rich Partridge, Enterprise Systems analyst with D.H. Brown Associates, "Thanks to its blend of high performance computation and robust communication, Cray's T3E was the leading MPP system for years. The Cray XT3 becomes the logical successor. Employing updated processor and interconnect technology, Cray again offers a highly scalable MPP design, with a balance of computation and communication capabilities that promises to deliver superior performance on real-world problems."

"The Cray XT3 supercomputer, designed in partnership with Sandia, advances the achievements of the Cray T3D and Cray T3E, widely recognized as the gold standard for MPP systems, as well as the ASCI Red supercomputer. The Cray XT3 sets a new standard for the efficient scalability and reliability of standard microprocessor-based system designs," said Peter Ungaro, Cray senior vice president for sales, marketing and services. "On real problems, the Cray XT3 system's balanced design will enable it to outperform large-scale clusters with substantially greater theoretical peak or Linpack (Top500) speed."

The Cray XT3 Supercomputer - Scalable By Design

The Cray XT3 supercomputer's high-bandwidth, low-latency design -- purpose-built for high performance computing (HPC) applications -- delivers a much higher percentage of peak performance in practice than HPC clusters and other alternatives.

The Cray XT3 supercomputer uses Advanced Micro Devices Inc.
HyperTransport technology and Opteron processors connected via a Cray low-latency, high-bandwidth, three-dimensional torus interconnect network.

   System highlights:

    --  A 3D torus direct connected processor (DCP) architecture
        tightly links processors to nearest neighbors.

    --  A highly scalable compute system incorporates high performance
AMD Opteron processors, high speed memory, an MPP
        optimized operating system, and a standards-based programming
        environment to deliver unmatched sustained application
        performance in configurations from 200 to 30,000 processors.

    --  A high bandwidth, low latency interconnect with embedded
        communications processing and routing offers total
        interconnect bandwidth of more than 100 terabytes/second.

    --  High speed, global I/O is scalable to over 100
        gigabytes/second of I/O (input/output) bandwidth and hundreds
        of terabytes of parallel disk storage.

    --  A tightly integrated management and operating system provides
        high reliability and is designed to run full-system
        applications to completion.
