Seymour Cray

Seymour Cray (Cray Seymour) (p. 1925 Chippeua Falls, pc. Wisconsin), an American electronics engineer, inventor of the supercomputer.

In 1950, Cray graduated from the University of Minnesota with a Bachelor of Electrical Engineering. He started his career with work on the UNIVAC I, the first commercially viable electronic digital computer of the first generation. In 1957 Cray helped the bottom "Control Deyta Corporation" (Control Data Corp., CDC), which has become a major producer of computers of its time. Created Kreem large computers CDC 6600 and CDC 7600 were of high operating speed.

In 1972, Cray left CDC, to organize his own company - "Cray Research, Inc. Incorporated" (Cray Research Inc.), Which is entertain the development of the most high-speed computers in the world. Newest invention Kreya steel multiprocessor computers, capable of simultaneous (parallel) processing. The first supercomputer company was released in 1976, "Cray-1". He was able to perform 240 million calculations per second and used for scientific research, such as modeling complex physical phenomena. These computers were purchased by government agencies and laboratories universistetskimi. The following models Kreya - Cray 1-M "and" Cray X-MP "had more capability. In 1981, Cray took off to chair his sprawling company and became an independent contractor of the company, while continuing to develop in his laboratory in Chippeua Falls increasingly fast cars.

In 1985, the market appeared "Cray-2, a machine that could perform 1200 million operations per second. Introduced in 1988, Cray Y-MP "possessed speed 2,670 million operations per second

. In 1989, Cray founded the Cray Computer Corporation "(Cray Computer Corporation), . but with the introduction of microprocessor technology and the reduction in demand for large computers in the military organizations (the era of the Cold War is over), . new company went bankrupt in 1995, . have not sold a single computer.,
