UK METEOROLOGICAL OFFICE ORDERS CRAY RESEARCH SUPERCOMPUTER EAGAN, Minn., Feb. 15, 1994 -- Cray Research, Inc. (NYSE:CYR) today announced that the United Kingdom Meteorological Office has ordered a CRAY C916 supercomputer. The system is scheduled to be installed at the organization's Bracknell, Berkshire, location later this quarter. With 140 gigabytes of disk storage and 256 million words of central memory, the fully loaded, 16 CPU system will be six times faster than each of the two CRAY Y-MP supercomputers it will replace. The new supercomputer will be used for climate prediction research and also to improve operational weather forecasting. Purchase of the system is being jointly funded by the U.K. Ministry of Defence for operational weather forecasting applications and by the U.K. Department of Environment for climate research. The CRAY C916 system will be particularly effective in advancing the U.K. DOE's Climate Prediction Programme carried out at the Meteorological Office's Hadley Centre for Climate Prediction and Research. The Centre's broad aims are to improve understanding, monitoring and modelling of the global climate system and its natural variability in order to detect and predict climate change. The increased speed and memory provided by the CRAY C916 system will accelerate the researchers' ability to develop, test, improve and maintain a hierarchy of atmosphere and ocean models, including, in particular, a state-of-the-art, fully-coupled Atomsphere- Ocean General Circulation Model. Refinement of such models is the main unifying component of the World Climate Research Programme. "The Hadley Centre will fully exploit its share of the C916 to make predictions, up to (the year) 2100, for the climate change expected to result from increasing concentrations of greenhouse gases, modified by natural and other anthropogenic influences, and also to provide a basis for predictions of regional climate change," said Dr. David Carson, Director, Hadley Centre for Climate Prediction and Research. "Cray Research has become the preferred supplier of high performance systems to the world's leading operational weather forecasting agencies," said John F. Carlson, Cray Research Chairman and chief executive officer. "Our products continue to prove themselves the best performing systems for demanding weather forecasting and climate research applications. We're pleased the U.K. Meteorological Office has chosen our top-of-the-line system to continue its work in these areas." Currently, Cray Research has more than 500 systems installed worldwide. There are 38 Cray Research systems installed at major weather forecasting and climate research centers in the U.S., Europe and other regions around the world. Cray Research creates the most powerful, highest-quality computational tools for solving the world's most challenging industrial and scientific problems. # # # -- -- Conrad Anderson Employee Communications (612) 683-7338
