massively parallel processing



  • A multiprocessing computer architecture in which multiple CPUs run parallel to each other during the execution of a single program or task. Each CPU has its own copy of the operating system, its own memory, its own copy of the application being run, and its share of the data. There can be most any number of CPUs working simultaneously. Also, processing in this manner. This contrasts with symmetric multiprocessing, where all the CPUs share the same memory, and the same copy of the operating system, application, and data being worked on. This also contrasts with asymmetric multiprocessing, in which multiple CPUs are each assigned a specific task, with all CPUs controlled by a master processor. Also called massively parallel. Its abbreviation is MPP.
