SEATTLE, WA--(MARKET WIRE)--Jul 29, 2008 -- Global supercomputer leader Cray Inc. (CRAY - News) today announced that researchers from the University of California-Irvine (UCI) have conducted the largest-ever fusion energy simulation on a Cray XT4™ supercomputer. Codenamed "Jaguar" and housed at Oak Ridge National Laboratory (ORNL), researchers harnessed the power of the highly scalable Cray system to simulate electron transport for a prototype fusion reactor developed to study the scientific and technological feasibility of fusion energy.

"Fusion holds the promise of a revolutionary new energy source for the world, and this important simulation has brought us one step closer to making it a reality," said Yong Xiao, the UCI researcher who led the unprecedented simulation of electron turbulent transport in fusion experiments. "Advances in high performance computing are key to advancing the science associated with identifying and developing alternative energy sources. The Cray XT4 system provided the scale, reliability and sustained performance required to handle the tremendous amount of data produced by complex fusion simulations."

Researchers speculate that fusion, the power source of the stars and sun, could provide a cleaner, more abundant energy source with far fewer harmful emissions than fossil-fuel burning power plants and fewer problems associated with waste than current nuclear power reactors.

"This is an important milestone and we applaud the efforts of the research team at UCI led by Yong Xiao and Zhihong Lin and the critical resources provided by ORNL's National Center for Computational Sciences," said Ian Miller, senior vice president of sales and marketing at Cray. "Cray systems are designed to tackle the most sophisticated and relevant challenges in science and engineering. This critical achievement is the result of the best minds in science converging with the highest innovation and scalability in high performance computing."

About the Cray XT4 Supercomputer

Building on the success of the Cray XT3™ system, the Cray XT4 is a massively parallel processor (MPP) supercomputer purpose-built to deliver exceptional sustained application performance for challenging scientific and engineering problems. The supercomputer's high-speed 3D torus interconnect, advanced MPP operating system and high-speed global input/output make it possible for users to scale applications to more than 120,000 processor cores with exceptional sustained performance. The system's scalable processing element uses x86 64-bit AMD Opteron™ processors that employ HyperTransport(TM) technology to increase bandwidth and reduce latency.
