[edit] SIMD multiprocessing Main article: SIMD In a single instruction stream, multiple data stream computer one processor handles a stream of instructions, each one of which can perform calculations in parallel on multiple data locations.

SIMD multiprocessing is well suited to parallel or vector processing, in which a very large set of data can be divided into parts that are individually subjected to identical but independent operations.

A single instruction stream directs the operation of multiple processing units to perform the same manipulations simultaneously on potentially large amounts of data.

For certain types of computing applications, this type of architecture can produce enormous increases in performance, in terms of the elapsed time required to complete a given task.

Our recognition resource and document library has subject briefs for the DP, looking at every subject at both standard and higher level.

The subject briefs cover core requirements, aims and assessment.[edit] MIMD multiprocessing Main article: MIMD MIMD multiprocessing architecture is suitable for a wide variety of tasks in which completely independent and parallel execution of instructions touching different sets of data can be put to productive use.For this reason, and because it is easy to implement, MIMD predominates in multiprocessing.Here is an example, however, please note, it is an example, the architecture in a console you want to mention, may differ, so you need to research that [I]"Software implementation issues edit Flynn's taxonomy Single instruction Multiple instruction Single data SISD MISD Multiple data SIMD MIMD See also: Software lockout [edit] SISD multiprocessing Main article: SISD In a single instruction stream, single data stream computer one processor sequentially processes instructions, each instruction processes one data item.One example is the "von Neumann" architecture with RISC.Some compilers in this category provide special constructs or extensions to allow programmers to directly specify operations to be performed in parallel (e.g., DO FOR ALL statements in the version of FORTRAN used on the ILLIAC IV, which was a SIMD multiprocessing supercomputer).SIMD multiprocessing finds wide use in certain domains such as computer simulation, but is of little use in general-purpose desktop and business computing environments.[citation needed] [edit] MISD multiprocessing Main article: MISD MISD multiprocessing offers mainly the advantage of redundancy, since multiple processing units perform the same tasks on the same data, reducing the chances of incorrect results if one of the units fails.Processing is divided into multiple threads, each with its own hardware processor state, within a single software-defined process or within multiple processes.Insofar as a system has multiple threads awaiting dispatch (either system or user threads), this architecture makes good use of hardware resources.To find them, open the 'DP subject briefs' panel in the resource and document library.
