  2. Asymmetric multiprocessing - Wikipedia

    en.wikipedia.org/wiki/Asymmetric_multiprocessing

    An asymmetric multiprocessing (AMP or ASMP) system is a multiprocessor computer system where not all of the multiple interconnected central processing units (CPUs) are treated equally. For example, a system might allow (either at the hardware or operating system level) only one CPU to execute operating system code or might allow only one CPU to ...

  3. 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 ...

  4. Multiprocessor system architecture - Wikipedia

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

    Symmetric multiprocessing system. Systems operating under a single OS (operating system) with two or more homogeneous processors and with a centralized shared main memory. A symmetric multiprocessor system (SMP) is a system with a pool of homogeneous processors running under a single OS with a centralized, shared main memory.

  5. Talk:Symmetric multiprocessing - Wikipedia

    en.wikipedia.org/wiki/Talk:Symmetric_multiprocessing

    This article is incorrect in its interpretation of SMP. SMP (Symmetric MultiProcessing) refers to the capability of any part of the operating system to execute on any processor. Asymmetric MP is a system where key portions of the OS such as IO operations can only execute on the primary CPU. Applications code can also execute on secondary CPUs.

  6. Non-uniform memory access - Wikipedia

    en.wikipedia.org/wiki/Non-uniform_memory_access

    Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). [ 1 ]

  7. Processor affinity - Wikipedia

    en.wikipedia.org/wiki/Processor_affinity

    For example, a system with two dual-core hyper-threaded CPUs presents a challenge to a scheduling algorithm. There is complete affinity between two virtual CPUs implemented on the same core via hyper-threading, partial affinity between two cores on the same physical processor (as the cores share some, but not all, cache), and no affinity ...

  8. Cache coherency protocols (examples) - Wikipedia

    en.wikipedia.org/wiki/Cache_coherency_protocols...

    Examples of coherency protocols for cache memory are listed here. For simplicity, all "miss" Read and Write status transactions which obviously come from state "I" (or miss of Tag), in the diagrams are not shown. They are shown directly on the new state. Many of the following protocols have only historical value.

  9. Multi-core processor - Wikipedia

    en.wikipedia.org/wiki/Multi-core_processor

    Since computer manufacturers have long implemented symmetric multiprocessing (SMP) designs using discrete CPUs, the issues regarding implementing multi-core processor architecture and supporting it with software are well known. Additionally: Using a proven processing-core design without architectural changes reduces design risk significantly.
