Massively Parallel Processing (MPP)
MPP (massively parallel processing) is the coordinated processing of a program by multiple processors that work on different parts of the program, with each processor using its own operating system and memory. An MPP system is also known as a "loosely coupled" or "shared nothing" system. Typically, MPP processors communicate using some messaging interface. In some implementations, up to 200 or more processors can work on the same application.
