Cray Announces General Availability of the Cray XD1 Opteron/Linux-based Supercomputer

SEATTLE--(BUSINESS WIRE)--Oct. 4, 2004--Global supercomputer leader Cray Inc. (Nasdaq:CRAY) today announced the general availability of the new Cray XD1(TM) supercomputer, an Opteron/Linux-based system priced from under $100,000 to about $2 million (U.S. list) that handily outperforms similarly priced Linux clusters. The company also announced the United States Department of Agriculture Forest Service is a Cray XD1 customer, which adds to an impressive list of early users, including the Ohio Supercomputer Center, the Pacific Northwest National Laboratory (PNNL), Germany's Helmut Schmidt University and the SAHA Institute of Nuclear Physics (Calcutta, India).

"Tracking the evolving chemical composition of a smoke plume produces a task so computationally intense that we assumed we would not be able to afford any computer capable of performing it," said Bryce Nordgren, Physical Scientist with the Forest Service's Fire Science Lab. "Reviewing the test case results from Cray restored our hope that we would be able to perform a scientifically meaningful simulation on our budget. We were particularly impressed with the Cray XD1's awesome scalability on this challenging interdisciplinary problem."

The Cray XD1 supercomputer is ideal for the special needs of high-performance computing (HPC) applications used by government and academia, as well as computer-aided engineering (CAE) in the aerospace, automotive and marine industries; weather forecasting and climate modeling; petroleum exploration; financial modeling; and life sciences research.

"We evaluated many proposals from leading IT companies and decided on Cray because of the Cray XD1 system's excellent price-to-performance ratio," said Professor Hendrik Rothe, chair of Helmut Schmidt University's Laboratory for Measurement and Information Technology.

According to Rich Partridge, Enterprise Systems analyst with D.H. Brown Associates, "With the XD1, Cray leverages its strong heritage to bring highly parallel, affordable supercomputing to a broad market of industrial, government and academic users. The Cray XD1 is not merely an Opteron/Linux parallel system; it is a 'Cray,' and that makes all the difference. This is a true supercomputer, with balanced performance that commodity designs just cannot achieve."

About the Cray XD1 Supercomputer

The Cray XD1 features the direct connect processor (DCP) architecture, which removes PCI bottlenecks and memory contention to deliver superior sustained performance. According to the HPC Challenge benchmarks, the Cray XD1 has the lowest latency of any HPC system, with MPI latency of 1.8 microseconds and random ring latency of 1.3 microseconds. Tests conducted by the Ohio Supercomputer Center show that the Cray XD1 ships messages with four times lower MPI latency than common cluster interconnects such as Infiniband, Quadrics or Myrinet, and 30 times lower than Gigabit Ethernet employed in lowest-cost clusters. The Cray XD1's interconnect delivers twice the bandwidth of 4X Infiniband for messages up to 1 KB and 60 percent higher throughput for very large messages.

The Linux/Opteron system runs x86 32/64 bit codes. Field programmable gate arrays (FPGAs) are available to accelerate applications, and the Active Manager subsystem provides single system command and control and high availability features. A 3VU (5.25") chassis provides 12 compute processors, 58 peak gigaflops, 96 GB/second aggregate switching capacity, 1.8-microsecond MPI interprocessor latency, 84 GB maximum memory and 1.5 TB maximum disk storage. A 12-chassis rack provides 144 compute processors, 691 peak gigaflops, 1TB/second aggregate switching capacity, 2 microsecond MPI interprocessor latency, 922 GB/second aggregate memory bandwidth, 1 TB maximum memory and 18 TB maximum disk storage.
