Seymore Cray; Cray Computer Corporation; Seymour R. Cray; Seymour Roger Cray; Cray, Seymour; SRC Computers

<person> The founder of Cray Research and designer of several of their supercomputers. Cray has been a charismatic yet somewhat reclusive figure. He began Cray Research in Minnesota in 1972. In 1988, Cray moved his Cray-3 project to Colorado Springs. The next year, Cray Research spun it off to create Cray Computer. In 1989, Cray left Cray Research and started Cray Computer Corporation in Colorado Springs. His quest to build a faster computer using new-generation materials failed in 1995, and his bankruptcy cost half a billion dollars and more than 400 jobs. The company was unable to raise $20 million needed to finish the Cray-4 and filed for bankruptcy in March 1995. In the summer of 1996, Cray started a Colorado Springs-based company called SRC Computers, Inc. "We think we'll build computers, but who knows what kind or how," Cray said at the time. "We'll talk it over and see if we can come up with a plan." On 1996-09-22, aged 70, Cray broke his neck in a car accident. Surgery for massive head injuries and swelling of the brain leaving him in a critical and unstable condition. (1997-03-02)

Cray-1

The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, 80 Cray-1s were sold, making it one of the most successful supercomputers in history. It is perhaps best known for its unique shape, a relatively small C-shaped cabinet with a ring of benches around the outside covering the power supplies and the cooling system.

The Cray-1 was the first supercomputer to successfully implement the vector processor design. These systems improve the performance of math operations by arranging memory and registers to quickly perform a single operation on a large set of data. Previous systems like the CDC STAR-100 and ASC had implemented these concepts but did so in a way that seriously limited their performance. The Cray-1 addressed these problems and produced a machine that ran several times faster than any similar design.

The Cray-1's architect was Seymour Cray; the chief engineer was Cray Research co-founder Lester Davis. They would go on to design several new machines using the same basic concepts, and retained the performance crown into the 1990s.
