Cray X-MP

The Cray X-MP was a supercomputer designed, built and sold by Cray Research. The company's first parallel vector processor machine and a fourth generation super, it was the 1982 successor to the 1976 Cray-1, and the world's fastest computer 1983–1985. The principal designer was Steve Chen.

The X-MP shared the 'horseshoe' design of the earlier machine and looked almost identical on the outside. The processors ran on a 10 nanosecond clock (compared to 12.5 ns for the Cray-1A), delivering a theoretical peak speed of 200 megaflops per processor and 800 megaflops for the four processor 1982 machine. The processors also had better chaining support, parallel arithmetic pipes, and shared memory access with multiple pipelines per processor.

Supercomputer: A supercomputer is a computer that leads the world in terms of processing capacity, particularly speed of calculation, at the time of its introduction. The term Super Computing was first used by New York World newspaper in 1920 to refer to the large custom built tabulators IBM had made for Columbia ...
