Korea Meteorological Administration's New Cray X1E Supercomputer Is World's Fastest Weather Prediction System

SEATTLE, WA AND SEOUL, KOREA, Feb 06, 2006 (MARKET WIRE via COMTEX News Network) -- Global supercomputer leader Cray Inc. (NASDAQ: CRAY) and the Korea Meteorological Administration (KMA) today announced that KMA has put into production the fastest operational numerical weather prediction system in the world. KMA takes advantage of the processing speed of its new Cray X1E(TM) supercomputer to facilitate development and operational services for long-range weather prediction and climate study, resulting in more accurate and timely weather, seasonal climate and ocean wave forecasts.

KMA's Cray X1E system, ranked number 16 on the TOP500 list of supercomputer sites published in November 2005, is equipped with 1,024 processors that deliver a peak performance of 18.5 teraflops (18.5 trillion floating point operations per second). The system became fully operational with an opening ceremony performed at KMA's supercomputing center in Seoul to mark the event.

"We at KMA are proud to host such an impressive capability and excited that our new Cray X1E system is up and running," said Dongil Lee, chief of the Supercomputer Center at KMA. "The system allows us to run very large-scale models and numerous ensemble members, as well as employ advanced data assimilation and model parameterization techniques, that will greatly benefit our predictive activities and scientific research. This helps us further our mission of ensuring public welfare through improved meteorology."

"We are delighted that the Cray X1E supercomputer passed KMA's rigorous acceptance process and is meeting their high expectations," said Per Nyberg, Cray's Director, Earth Sciences Segment. "The launch of this new system, together with Cray's involvement in KMA's Earth System Research Center, underscores our close relationship with KMA and emphasizes the important role Cray products play in operational weather forecasting worldwide."

About the Cray X1E Supercomputer

The Cray X1E system delivers maximum performance for the world's most challenging computational problems by combining the processor performance of traditional vector systems with the scalability of microprocessor-based architectures. High performance interconnect and memory subsystems allow the Cray X1E system to scale from 16 to 8,192 processors, delivering up to 147 teraflops in a single system. The Cray X1E supercomputer and its predecessor, the Cray X1(TM) supercomputer, are the first vector systems designed to scale to thousands of processors in a single system image.
