Cray SX-6 Installed at ARSC

Fairbanks, Alaska - The Arctic Region Supercomputing Center (ARSC) and Cray Inc. (Nasdaq NM: CRAY) announced today an agreement that places a Cray SX-6 at ARSC. ARSC is pleased to be able to offer this leading technology to the wider High Performance Computing (HPC) community for testing and evaluation. This is the first installation of a Cray SX-6 system in the United States under the OEM agreement concluded last year between Cray Inc. and NEC. New users should be able to access the system by mid-July.

Under the agreement, the Cray SX-6 installed at ARSC will remain at the center for 12 months. During this time, ARSC will manage and operate the system and intends to develop comparative benchmarks for users' applications across the architectures available at ARSC. Other objectives will be to help researchers make effective use of the SX-6 vector environment, and to explore how different levels of information security can be achieved. Cray Inc. will have shared use of the SX-6 while it is in Fairbanks for applications development, benchmarking and sponsored users.

"Providing access to SX-6 technology, the same fundamental technology found in the Earth Simulator, will greatly advantage computational scientists and staff supporting HPC resources," said Dr. Frank Williams, ARSC's director. "I'm looking forward to a robust evaluation of this additional tool for solving the largest and most difficult of computational problems."

The system, named Rime, has eight processors, 64 gigabytes of memory, 1 terabyte disk and a 500 MHz system clock. System peak performance is 64 GFLOPS. The name Rime, which means a frost or granular ice coating on objects that is formed from supercooled cloud or fog, fits well with the system's particular capabilities for use with weather and climate programs.

The Cray SX-6 vector processor is fully contained on a single chip, unlike the previous generation SX Series system that required 32 chips for equivalent performance and functionality. The uniform shared memory of the single-node Cray SX-6 supercomputer provides uniquely high bandwidth and reduced latency to ensure the highest levels of sustained performance.

The Arctic Region Supercomputing Center, located on the campus of the University of Alaska Fairbanks, supports computational research in science and engineering with emphasis on high latitudes and the Arctic. The center provides high performance computational, visualization, networking and data storage resources for researchers within the University of Alaska, other academic institutions, the Department of Defense and other government agencies. ARSC is a DoD Supercomputing Resource Center in the Department of Defense's High Performance Computing Modernization Program. For additional information about ARSC, go to www.arsc.edu.
