Cray makes computers that aren't just good -- they're super. Its massively parallel and vector supercomputers provide the firepower behind research ranging from weather forecasting and scientific research to design engineering and classified government projects. The company also provides maintenance and support services, and it sells data storage products from partners including BlueArc, LSI, and Quantum. Its largest customer is the US government; agencies such as DARPA and the Oak Ridge National Laboratory account for about three-quarters of revenue. Cray also targets academic institutions and industrial companies. The company primarily utilizes a direct sales force from offices in Europe and Asia-Pacific.
