*#REDIRECT [[Massively parallel]] ▼'''Massive parallel processing''' ('''MPP''') is a term used in [[computer architecture]] to refer to a computer system with many independent [[arithmetic]] units or entire [[microprocessor]]s, that run in parallel. The term ''massive'' connotes hundreds if not thousands of such units. Early examples of such a system are the [[Distributed Array Processor]], the [[Goodyear MPP|Goodyear MP]], the [[Connection Machine]], and the [[Ultracomputer]].
{{Redirect category shell|1=
Today's most powerful [[supercomputer]]s are all ''MP'' systems such as [[Earth Simulator]], [[Blue Gene]], [[ASCI White]], [[ASCI Red]], [[ASCI Purple]], [[ASCI Thor's Hammer]].

In this class of computing, all of the processing elements are connected together to be one very large computer. This is in contrast to [[distributed computing]] where massive numbers of separate computers are used to solve a single problem.
Through advances in [[Moore's Law]], [[System-on-Chip]] (SOC) implementations of massively parallel architectures are becoming cost effective, and finding particular application in high definition video processing. Examples include chips from [[Ambric]], [[Picochip|picoChip]], and [[Tilera]].
