On this day in 1985 the Cray X-MP/48 supercomputer began operating at the San Diego Supercomputer Center. The supercomputer was designed, built and sold by Cray Research and was the world’s fastest computer from 1983 to 1985. With its parallel processing system, it could process 420 megaflops– nearly double the speed of its competitors at the time. The Cray X-MP could work even faster when two were arranged to work together on different parts of the same problem.
