C.mmp

The C.mmp was an early multiple instruction, multiple data (MIMD) multiprocessor system developed at Carnegie Mellon University (CMU) by William Wulf (1971). The notation C.mmp came from the PMS notation of Gordon Bell and Allen Newell, where a central processing unit (CPU) was designated as C, a variant was noted by the dot notation, and mmp stood for Multi-Mini-Processor. As of 2020, the machine is on display at CMU, in Wean Hall, on the ninth floor.
