Massively parallel processing

The term mass parallel computer (MPR) or English massively parallel processing (MPP) describes in computer science the distribution of a task to several main processors , each of which can also have its own main memory . A massively parallel computer is therefore a parallel computer , the (partly several thousands) has independent execution units via a plurality. The mainframe computers from the BlueGene series from IBM are an example of this .

In contrast to normal multiprocessor systems , the term can also designate architectures in which the complexity of the individual processor (measured e.g. by the number of transistors used ) is reduced in order to enable a higher number of parallel computing units.
