SUPRENUM
SUPRENUM was a German research project to develop a parallel computer from 1985 through 1990. It was a major effort which was aimed at developing a national expertise in massively parallel processing both at hardware and at software level.
Although the Suprenum-1 computer was the fastest massively parallel MIMD computer in the world during a period in 1992, the project was set and is considered a commercial failure.
