2. 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 ...

3. 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 ...

4. 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.

5. 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 ...

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. Process (computing) - Wikipedia

   en.wikipedia.org/wiki/Process_(computing)

   Several processes may be associated with the same program; for example, opening up several instances of the same program often results in more than one process being executed. Multitasking is a method to allow multiple processes to share processors (CPUs) and other system resources. Each CPU (core) executes a single process at a time.

8. Real-time computing - Wikipedia

   en.wikipedia.org/wiki/Real-time_computing

   Soft real-time systems are typically used to solve issues of concurrent access and the need to keep a number of connected systems up-to-date through changing situations. Some examples of soft real-time systems: Software that maintains and updates the flight plans for commercial airliners. The flight plans must be kept reasonably current, but ...

9. Simultaneous and heterogeneous multithreading - Wikipedia

   en.wikipedia.org/wiki/Simultaneous_and...

   Simultaneous and heterogeneous multithreading (SHMT) is a software framework that takes advantage of heterogeneous computing systems that contain a mixture of central processing units (CPUs), graphics processing units (GPUs), and special purpose machine learning hardware, for example Tensor Processing Units (TPUs).
