  1. Cray By Andrew Colby

  2. Seymour Cray • Died at age 71 • Founder of Cray Research • Father of supercomputing • Went through many positions in company • Created the computer cooling system http://www.cray.com/about_cray/history.html

  3. Seymour Cray • Left company for computer engineering • Based all his work on simplicity • Quality and speed above price

  4. Cray-1 • One of the first super computers • Installed - Los Alamos National Laboratory • Speed - 160 megaflops • 8 megabyte memory • C shaped to maintain space • No unneeded circuitry

  5. Cray-1 • 100 million arithmetic operations per second • Cooling system to keep from melting • Cost $700,000 US Dollars in 1976 • Circuitry less than four feet long • Around 85 units sold

  6. Timeline of Seymour Cray’s Work 1950-The 1101 computer, was originally known as the Atlas and was designed for military applications. Frank Mullaney, the first Chairman of the Board for Cray Research, was a design engineer for this machine. 1970-Serial No. 3 was assembled in Chippewa Falls and shipped to the Los Alamos Scientific Laboratory for use in nuclear research. 1953-The first machine that many of Cray Research’s founders worked on was the UNIVAC 1103 scientific computer designed by ERA. 1972-Former CDC founders Seymour Cray, Frank Mullaney, George Hanson, and Noel Stone, formed Cray Research.The new company, which established its headquarters in Chippewa Falls, began its operations with engineering teams headed by Les Davis, Dean Roush, and Harry Runke. The 1103 computer weighed about 14 tons, and the mainframe occupied 612 sq ft.The first few 1103 computers used vacuum tube memory; ferrite core technology was applied to later models. Five wires went through each core in the matrix.

  7. Timeline of Seymour Cray’s Work • 1976-Serial No. 1 of the Cray-1 computer system, the company’s first product, was powered and officially introduced. The National Center for Atmospheric Research NCAR was Cray Research’s first official customer. 1982-In September of 1982, the CRAY-1M system, the last Cray-1 series of computer systems was announced. Only nine CRAY-1M systems were built before they were replaced in the product line by single processor CRAY X-MP systems, which featured the same high performance CPU as the rest of the CRAY X-MP series. 1988The CRAY X-MP series of computer systems was one of Cray Research’s most popular products to date, with 189 produced. • 1989-Cray formed Cray Computer Corporation (CCC) in Colorado Springs, Colorado • Cray Research announced the CRAY X-MP, its first multiprocessor computer.  With their 9.5 ns clocks, the two CPUs for the CRAY X-MP system were significantly faster than those for the CRAY-1 system.  The IOS, having proven its worth, became a standard feature.  • 1993-Cray 3 project canceled • 1994-Cray Computer Corp releases the Cray-4
