The '''Cray X-MP''' was a [[supercomputer]] designed, built and sold by [[Cray|Cray Research]]. It was announced in 1982 as the "cleaned up" successor to the 1975 [[Cray-1]], and was the world's fastest computer from 1983 to 1985 with a quad-processor system performance of 800 [[MFLOPS]].<ref>{{cite book |last=Steinhauser |first=Martin Oliver |title=Computational Multiscale Modeling of Fluids and Solids: Theory and Applications |url=https://books.google.com/books?id=Ilzans7dWTQC&dq=Cray+X-MP+world%27s+fastest+computer&pg=PA20 |year=2008 |publisher=Springer |isbn=9783540751168 |page=21}}</ref> The principal designer was [[Steve Chen (computer engineer)|Steve Chen]].
