Oakland, California

SUSE Linux today announced that it has been chosen by Cray Inc. (NASDAQ: CRAY) to drive key aspects of the Department of Energy's new massively parallel processing (MPP) supercomputer called Red Storm at Sandia National Laboratories.

Red Storm is expected to become operational in the late 2004 timeframe and will use Advanced Micro Devices Inc. (NYSE: AMD) AMD OpteronT processors featuring HyperTransportT technology in conjunction with Red Storm's high-bandwidth, low-latency internal switching architecture. The Sandia National Laboratories Red Storm supercomputer will be used for computer simulations of the U.S. nuclear stockpile and other applications. The new Red Storm supercomputer demonstrates a strong commitment by the Department of Energy to providing the innovative technology needed to support the nation's nuclear stockpile stewardship program.

SUSE Linux Enterprise Server for AMD64 technology combines the stability and security of Linux with the performance enhancements available only through the 64-bit architecture.

SUSE agreement with Cray Inc. will also include developer support from SuSE. "We look forward to working with Cray, a leader in the high-performance computing arena, on this crucial initiative," said Holger Dyroff, US General Manager, SUSE Linux. "The selection of SuSE for the Department of Energy's new MPP supercomputer demonstrates the stability, scalability and performance of SUSE Linux Enterprise Server on AMD Opteron."

SUSE Linux Enterprise Server for AMD64 comes with an optimized kernel that enables high availability solutions and the high-performance interaction with storage systems in the SAN by means of asynchronous I/O and multipathing memory access.

"We selected SUSE Linux Enterprise Server for AMD64 because it combines innovative Linux technology with a powerful architecture for high-performance computing," said Wayne Kugel, Cray's executive of operations for the Red Storm initiative. "SUSE Linux Enterprise Server is a strong operating system for high performance computing and we are excited about our collaboration on this project."
