'''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]], the [[Connection Machine]], and the [[Ultracomputer]].'''MPP really stands for menbers of provincal parliment
'''
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.
{{Redirect category shell|1=
The earliest massively parallel processing systems all used [[serial computer]]s as individual processing elements, in order to achieve the maximum number of independent units for a given size and cost.

Through advances in [[Moore's Law]], single-chip implementations of [[massively parallel processor array]]s are becoming cost effective, and finding particular application in high performance [[embedded systems]] applications such as [[video compression]]. Examples include chips from [[Ambric]], [http://www.coherentlogix.com Coherent Logix], [[Picochip|picoChip]], and [[Tilera]].
