Massively parallel (computing)

In computing, massively parallel refers to the use of a large number of processors or separate computers to perform a set of coordinated computations in parallel simultaneously

In one approach, eg, in grid computing the processing power of a large number of computers in distributed, diverse administrative domains, is opportunistically used whenever a computer is available1 An example is BOINC, a volunteer-based, opportunistic grid system, whereby the grid provides power only on a best effort basis2

In another approach, a large number of processors are used in close proximity to each other, eg, in a computer cluster In such a centralized system the speed and flexibility of the interconnect becomes very important, and modern supercomputers have used various approaches ranging from enhanced Infiniband systems to three-dimensional torus interconnects3

The term also applies to massively parallel processor arrays MPPAs, a type of integrated circuit with an array of hundreds or thousands of central processing units CPUs and random-access memory RAM banks These processors pass work to one another through a reconfigurable interconnect of channels By harnessing a large number of processors working in parallel, an MPPA chip can accomplish more demanding tasks than conventional chipscitation needed MPPAs are based on a software parallel programming model for developing high-performance embedded system applications

Goodyear MPP was an early implementation of a massively parallel computer architecture MPP architectures are the second most common supercomputer implementations after clusters, as of November 20134 Examples of services and products which has a MPP implementation include Microsoft's Azure SQL Data Warehouse and Microsoft’s on premise data warehousing product, Parallel Data Warehouse PDW, which runs on the Analytics Platform System APS
