MasPar (Score 4, Interesting)

For several years I worked on a SIMD system called MasPar. The system had 8192 processors. It was installed in 1991 and it was not until about 1998 that conventional computers running Oracle could even come close to the performance for data warehouse applications. Sure, it's slow by today's standards, but I bet a modern version custom built would be an awesome code breaking and data analysis system.
BTW: the system was used to help with the human genome project and to search Medical Services Plan data by the Province of BC. It finally decommissioned in 2000 (or early 2001).
