.
It was designed to deliver enormous computational power at lower cost than
other existing supercomputer architectures, by using thousands of
simple processing elements, rather than one or a few highly complex CPUs.
Development of the MPP began circa 1979; it was delivered in May 1983,
and was in general use from 1985 until 1991.

It was based on Goodyear's earlier STARAN

STARAN

STARAN might be the first commercially available computer designed around an associative memory. The STARAN computer was designed and built by Goodyear Aerospace Corporation. It is a Content Addressable Parallel Processor, a type of parallel processor which uses content addressable memory...
