2. Concurrent computing - Wikipedia

   en.wikipedia.org/wiki/Concurrent_computing

   For example, concurrent processes can be executed on one core by interleaving the execution steps of each process via time-sharing slices: only one process runs at a time, and if it does not complete during its time slice, it is paused, another process begins or resumes, and then later the original process is resumed. In this way, multiple ...

3. Multiple instruction, multiple data - Wikipedia

   en.wikipedia.org/wiki/Multiple_instruction...

   Systems were designed to reduce this time loss and hypercube and mesh are among two of the popular interconnection schemes. Examples of distributed memory (multiple computers) include MPP (massively parallel processors), COW (clusters of workstations) and NUMA (non-uniform memory access). The former is complex and expensive: Many super ...

4. Computer multitasking - Wikipedia

   en.wikipedia.org/wiki/Computer_multitasking

   Often multitasking operating systems include measures to change the priority of individual tasks, so that important jobs receive more processor time than those considered less significant. Depending on the operating system, a task might be as large as an entire application program, or might be made up of smaller threads that carry out portions ...

5. Single instruction, multiple threads - Wikipedia

   en.wikipedia.org/wiki/Single_instruction...

   Single instruction, multiple threads (SIMT) is an execution model used in parallel computing where single instruction, multiple data (SIMD) is combined with multithreading. It is different from SPMD in that all instructions in all "threads" are executed in lock-step.

6. Concurrency (computer science) - Wikipedia

   en.wikipedia.org/wiki/Concurrency_(computer_science)

   For example, Lee and Sangiovanni-Vincentelli have demonstrated that a so-called "tagged-signal" model can be used to provide a common framework for defining the denotational semantics of a variety of different models of concurrency, [11] while Nielsen, Sassone, and Winskel have demonstrated that category theory can be used to provide a similar ...

7. Real-time operating system - Wikipedia

   en.wikipedia.org/wiki/Real-time_operating_system

   A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix , which manages the sharing of system resources with a scheduler, data buffers, or fixed task ...

8. Multithreading (computer architecture) - Wikipedia

   en.wikipedia.org/wiki/Multithreading_(computer...

   This type of multithreading is known as block, cooperative or coarse-grained multithreading. The goal of multithreading hardware support is to allow quick switching between a blocked thread and another thread ready to run. Switching from one thread to another means the hardware switches from using one register set to another.

9. Simultaneous multithreading - Wikipedia

   en.wikipedia.org/wiki/Simultaneous_multithreading

   Coarse-grain multithreading is more common for less context switch between threads. 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 ...
