The Goodyear Massively Parallel Processor
) was amassively parallel processing supercomputer
built by Goodyear Aerospace
for the NASA Goddard Space Flight Center
.It was designed to deliver enormous computational power at lower cost thanother existing supercomputer architectures, by using thousands ofsimple 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
array processor, a 4x256 1-bit processing element (PE) computer.The MPP was a 128x128 2-dimensional array of 1-bit wide PEs. In actuality 132x128 PEs were configured with a 4x128 configuration added for fault tolerance to substitute for up to 4 rows (or columns) of processors in the presence of problems.The PEs operated in an SIMD
(Single Instruction, Multiple Data) fashion -each processor performed the same operations simultaneously, on different dataelements, under the control of a microprogrammed control unit.
After the MPP was retired in 1991, it was donated to the Smithsonian Institution
,and is now in the collection of the National Air and Space Museum
's Steven F. Udvar-Hazy Center
. It was succeeded at Goddard by MasPar
MP-1 andCray T3D
massively parallel computers.
The MPP was initially developed for high-speed analysis of satellite
images.In early tests, it was able to extract and separate different land-use areas on Landsat
