  2. Thread (computing) - Wikipedia

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

    A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.

  3. Java concurrency - Wikipedia

    en.wikipedia.org/wiki/Java_concurrency

    The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming.All execution takes place in the context of threads.Objects and resources can be accessed by many separate threads.

  4. Multithreading (computer architecture) - Wikipedia

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

    Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs). As a result, execution times of a single thread are not improved and can be degraded, even when only one thread is executing, due to lower frequencies or additional pipeline stages that are necessary to accommodate thread-switching hardware.

  5. Java memory model - Wikipedia

    en.wikipedia.org/wiki/Java_memory_model

    For the execution of a single thread, the rules are simple. The Java Language Specification requires a Java virtual machine to observe within-thread as-if-serial semantics. The runtime (which, in this case, usually refers to the dynamic compiler, the processor and the memory subsystem) is free to introduce any useful execution optimizations as ...

  6. Thread pool - Wikipedia

    en.wikipedia.org/wiki/Thread_pool

    A sample thread pool (green boxes) with waiting tasks (blue) and completed tasks (yellow) In computer programming, a thread pool is a software design pattern for achieving concurrency of execution in a computer program.

  7. Concurrent computing - Wikipedia

    en.wikipedia.org/wiki/Concurrent_computing

    Concurrent components communicate by altering the contents of shared memory locations (exemplified by Java and C#). This style of concurrent programming usually needs the use of some form of locking (e.g., mutexes, semaphores, or monitors) to coordinate between threads. A program that properly implements any of these is said to be thread-safe.

  8. Virtual thread - Wikipedia

    en.wikipedia.org/wiki/Virtual_thread

    In computer programming, a virtual thread is a thread that is managed by a runtime library or virtual machine (VM) and made to resemble "real" operating system thread to code executing on it, while requiring substantially fewer resources than the latter.

  9. pthreads - Wikipedia

    en.wikipedia.org/wiki/Pthreads

    POSIX Threads is an API defined by the Institute of Electrical and Electronics Engineers (IEEE) standard POSIX.1c, Threads extensions (IEEE Std 1003.1c-1995). Implementations of the API are available on many Unix-like POSIX-conformant operating systems such as FreeBSD , NetBSD , OpenBSD , Linux , macOS , Android [ 1 ] , Solaris , Redox , and ...
