Cray/Media:Mardi Larson, 612/683-3538 Cray/Financial:Brad Allen, 612/683-7395 FRENCH AUTOMAKER PSA PEUGEOT-CITROEN ORDERS CLUSTER OF SIX CRAY SUPERCOMPUTERS FOR CRASH ANALYSIS EAGAN, Minn., March 12, 1996 -- French automaker PSA Peugeot Citroen, Paris, has ordered and is now installing six CRAY J90 supercomputer systems, Cray Research, Inc. (NYSE:CYR) announced today. Five of the systems will be used to conduct crash analysis simulations for the company's new Peugeot and Citroen car models. Terms were not disclosed. "Our goal is to decentralize crash simulations from our high- end CRAY C90 supercomputer by moving them closer to the teams doing the analysis work in departments and groups throughout our organization," said Jean-Serge Bertoncini, Chief Information Officer of PSA Peugeot-Citroen Group. "We can place these six CRAY J90 air-cooled supercomputers systems in office environments on our corporate network while the compatible CRAY C90 is dedicated to other intensive CAE applications." According to PSA Peugeot-Citroen officials, the Cray(R) systems were selected under a competitive bid. The company's main requirement was the ability to fully and efficiently support the parallel-vector version of RADIOSS, a popular crash analysis code used by the automotive industry. Cray has supported RADIOSS for more than six years on its parallel- vector supercomputers and is the performance leader on this application. Bertoncini said Cray's Network Queuing Environment (NQE) network load balancing software, which helps customers get the most from their clustered systems, was an attractive feature in Cray's proposal. NQE automatically monitors the systems on a local area network and ensures that no one system is overwhelmed with work while another sits idle. Peugeot-Citroen will use this software on the CRAY J90 cluster for balancing the day-to-day crash analysis workload for the company. Cray Research provides the leading high-performance computing tools services to help solve customers' most challenging problems. ###
