  2. Multiprocessor system architecture - Wikipedia

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

    A cc–NUMA system is a cluster of SMP systems – each called a "node", which can have a single processor, a multi-core processor, or a mix of the two, of one or other kinds of architecture – connected via a high-speed "connection network" that can be a "link" that can be a single or double-reverse ring, or multi-ring, point-to-point ...

  3. Multiprocessing - Wikipedia

    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. Task Control Block - Wikipedia

    en.wikipedia.org/wiki/Task_Control_Block

    With the introduction of MVS/370 and successor systems, a whole new environment was introduced: the Service Request Block (SRB), which generally has a higher priority than any Task Control Block, and, indeed, which itself has two distinct priorities: a Global SRB (priority over all local address space SRBs and TCBs) and a Local SRB (priority over only the local address space TCBs); and MVS's ...

  5. Simultaneous multithreading - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_multithreading

    For example, Intel's Montecito processor uses coarse-grained multithreading, while Sun's UltraSPARC T1 uses fine-grained multithreading. For those processors that have only one pipeline per core, interleaved multithreading is the only possible way, because it can issue at most one instruction per cycle.

  6. 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 ...

  7. UltraSPARC T2 - Wikipedia

    en.wikipedia.org/wiki/UltraSPARC_T2

    Sun Microsystems' UltraSPARC T2 microprocessor is a multithreading, multi-core CPU. It is a member of the SPARC family, and the successor to the UltraSPARC T1. The chip is sometimes referred to by its codename, Niagara 2. Sun started selling servers with the T2 processor in October 2007.

  8. Tilera - Wikipedia

    en.wikipedia.org/wiki/Tilera

    Tilera's primary product family was the Tile CPU. Tile is a multicore design, with the cores communicating via a new mesh architecture, called iMesh, intended to scale to hundreds of cores on a single chip.

  9. CPU shielding - Wikipedia

    en.wikipedia.org/wiki/CPU_shielding

    CPU shielding is a practice where on a multiprocessor system or on a CPU with multiple cores, real-time tasks can run on one CPU or core while non-real-time tasks run on another. The operating system must be able to set a CPU affinity for both processes and interrupts .
