EUROPEAN CENTRE FOR MEDIUM-RANGE WEATHER FORECASTS ORDERS CRAY T3D MASSIVELY PARALLEL PROCESSING SYSTEM

 EAGAN, Minn., Oct. 19 /PRNewswire/ -- Cray Research, Inc. (NYSE: CYR) announced today that the European Centre for Medium-Range Weather Forecasts (ECMWF) has ordered a CRAY T3D massively parallel processing system. The CRAY T3D system will be closely coupled with a
 CRAY Y-MP2E parallel vector supercomputer system also ordered by ECMWF. Both systems are scheduled to be installed at the Centre's Reading, England operations in mid-1994.
 ECMWF has ordered a CRAY T3D MCA64-8, a 64-processor, air-cooled system. Terms were not disclosed. This is one of the nine initial orders referred to in the Sept. 27 CRAY T3D product announcement.
 ECMWF will use the CRAY T3D to develop new forecasting models that take advantage of MPP technology, and also to run the Centre's ensemble prediction system. This system is used to generate forecasts provided to 18 national weather services throughout Europe.
 In ensemble forecasting, meteorologists run multiple versions of a forecasting model, varying the data describing initial weather conditions with each run. This extremely computation-intensive technique is used to improve the accuracy of forecasts by determining their sensitivity to variations in initial weather conditions.
 ECMWF currently runs the ensemble prediction system on a CRAY C916 delivered in 1992, which will continue to serve as ECMWF's main resource for most forecasting work. ECMWF was the first international customer for the CRAY C916, Cray's top-of-the-line parallel vector system.
 "Our customers have been pleased with the quality of the forecasts generated by our ensemble prediction system and would like us to run the model more frequently," said Dr. David Burridge, director of ECMWF. "With the CRAY T3D, we hope to increase the number of runs from the current three times a week to seven times a week."
 John F. Carlson, Cray Research chairman and CEO, said, "Our partnership with ECMWF began in the late1970s when the Centre took delivery of a CRAY 1, continued with several subsequent deliveries, and now progresses to a new stage with the Centre's order for the T3D. We're pleased that we've been able to meet the Centre's growing need for robust, reliable supercomputing power to improve forecasting accuracy."
 ECMWF is funded by 18 European states.
