Cray-2
From open-encyclopedia.com - the free encyclopedia.
The Cray-2 was a vector supercomputer offered by Cray Research beginning in 1985. It replaced Cray's own X-MP, which until then was the world's fastest computer. The Cray-2 was bumped off of the top spot by the ETA-10G in 1990.
The Cray-2 was predominantly developed for the American Departments of Defense and Energy, who comprised the chief customers. Uses tended to be for nuclear weapons research or oceanographic (sonar) development. However, the Cray-2 also found its way into civil agencies (such as NASA Ames Research Center), universities, and corporations worldwide.
The Cray-2 would have been superceded by the Cray-3, but due to development problems, that system never saw fruition. The spiritual descendant of the Cray-2 is the Cray X1, offered by Cray Inc.
