  2. Multiprocessor system architecture - Wikipedia

    en.wikipedia.org/wiki/Multiprocessor_system...

    A multiprocessor system is defined as "a system with more than one processor", and, more precisely, "a number of central processing units linked together to enable parallel processing to take place". [1] [2] [3] The key objective of a multiprocessor is to boost a system's execution speed. The other objectives are fault tolerance and application ...

    en.wikipedia.org/wiki/Multiprocessing

    An early example of a master/slave multiprocessor system of microprocessors is the Tandy/Radio Shack TRS-80 Model 16 desktop computer which came out in February 1982 and ran the multi-user/multi-tasking Xenix operating system, Microsoft's version of UNIX (called TRS-XENIX).

  4. Multiple instruction, multiple data - Wikipedia

    The diameter of the system is the minimum number of steps it takes for one processor to send a message to the processor that is the farthest away. So, for example, the diameter of a 2-cube is 2. In a hypercube system with eight processors and each processor and memory module being placed in the vertex of a cube, the diameter is 3.

  5. Symmetric multiprocessing - Wikipedia

    en.wikipedia.org/wiki/Symmetric_multiprocessing

    Diagram of a symmetric multiprocessing system. Symmetric multiprocessing or shared-memory multiprocessing [1] (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all ...

  6. Task parallelism - Wikipedia

    en.wikipedia.org/wiki/Task_parallelism

    As a simple example, if a system is running code on a 2-processor system (CPUs "a" & "b") in a parallel environment and we wish to do tasks "A" and "B", it is possible to tell CPU "a" to do task "A" and CPU "b" to do task "B" simultaneously, thereby reducing the run time of the execution.

  7. Multi-core processor - Wikipedia

    en.wikipedia.org/wiki/Multi-core_processor

    This then requires the use of numerical libraries to access code written in languages like C and Fortran, which perform math computations faster [citation needed] than newer languages like C#. Intel's MKL and AMD's ACML are written in these native languages and take advantage of multi-core processing. Balancing the application workload across ...

  8. Parallel computing - Wikipedia

    en.wikipedia.org/wiki/Parallel_computing

    In 1969, Honeywell introduced its first Multics system, a symmetric multiprocessor system capable of running up to eight processors in parallel. [79] C.mmp, a multi-processor project at Carnegie Mellon University in the 1970s, was among the first multiprocessors with more than a few processors. The first bus-connected multiprocessor with ...

  9. OpenMP - Wikipedia

    en.wikipedia.org/wiki/OpenMP

    OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, [3] on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows.
