Cray-2

The Cray-2 was a supercomputer with four vector processors built with emitter-coupled logic and made by Cray Research starting in 1985. At 1.9 GFLOPS peak performance, it was the fastest machine in the world when it was released, replacing the Cray X-MP in that spot. The Cray-2 was replaced as the world's fastest computer by the ETA-10G in 1990.

Initial design

With the successful launch of his famed Cray-1, Seymour Cray turned to the design of its successor. By 1979 he had become fed up with management interruptions in what was now a large company, and as he had done in the past, decided to resign his management post and move to form a new lab. As with his original move to Chippewa Falls, Wisconsin from Control Data HQ in Minneapolis, Minnesota, Cray management understood his needs and supported his move to a new lab in Boulder, Colorado. Working as an independent consultant at these new Cray Labs, he put together a team and started on a completely new design. This Lab would later close, and a decade later a new facility in Colorado Springs would open.
