multithreading
多線

Sharing a single {CPU} between multiple tasks (or
"threads") in a way designed to minimise the time required to
switch threads. This is accomplished by sharing as much as
possible of the program execution environment between the
different threads so that very little state needs to be saved
and restored when changing thread.

Multithreading differs from {multitasking} in that threads
share more of their environment with each other than do tasks
under multitasking. Threads may be distinguished only by the
value of their {program counters} and {stack pointers} while
sharing a single {address space} and set of {global
variables}. There is thus very little protection of one
thread from another, in contrast to multitasking.

Multithreading can thus be used for very fine-grain
multitasking, at the level of a few instructions, and so can
hide {latency} by keeping the processor busy after one thread
issues a long-latency instruction on which subsequent
instructions in that thread depend.

A {light-weight process} is somewhere between a thread and a
full process.

{TL0} is an example of a threaded machine language.
{Dataflow} computation (E.g. {Id} and {SISAL}) is an extreme
form of multithreading.

  • What is multithreading? - IONOS
    How does multithreading work? Multithreading is the result of interactions between hardware and software Programs and processes are broken down into individual threads, which are then processed in order to execute the program We make the distinction between hardware multithreading and software multithreading
  • multithreading - What is a multithreaded application? - Stack Overflow
    Multithreading as a widespread programming and execution model allows multiple threads to exist within the context of a single process These threads share the process' resources but are able to execute independently The threaded programming model provides developers with a useful abstraction of concurrent execution However, perhaps the most interesting application of the technology is when
  • multithreading - How do I use threading in Python? - Stack Overflow
    19 With borrowing from this post we know about choosing between the multithreading, multiprocessing, and async asyncio and their usage Python 3 has a new built-in library in order to make concurrency and parallelism — concurrent futures So I'll demonstrate through an experiment to run four tasks (i e sleep() method) by Threading-Pool
  • multiprocessing vs multithreading vs asyncio - Stack Overflow
    Multithreading Python multithreading allows you to spawn multiple threads within the process These threads can share the same memory and resources of the process
  • How exactly does multithreading work? - Stack Overflow
    Multithreading lets run more than one thread at once On a multicore machine, this means two threads can really run in parallel, doing twice the work they'd do running one at a time Ideally, on a 4 core machine, with 4 threads you'll get almost 4 times as much work done as with a single thread For this to work, you need a problem that can be solved with multiple threads running somewhat

    What are some concrete examples of applications that need to be multi-threaded, or don't need to be, but are much better that way? Answers would be best if in the form of one application per post
  • What is the difference between asynchronous programming and multithreading?
    The async and await keywords don't cause additional threads to be created Async methods don't require multithreading because an async method doesn't run on its own thread The method runs on the current synchronization context and uses time on the thread only when the method is active
  • multithreading - Multiprocessing vs Threading Python - Stack Overflow
    Multithreading cannot achieve this because the GIL prevents threads from running in parallel As a consequence, threading may not always be useful in Python, and in fact, may even result in worse performance depending on what you are trying to achieve
  • multithreading - What is a race condition? - Stack Overflow
    When writing multithreaded applications, one of the most common problems experienced is race conditions My questions to the community are: What is the race condition? How do you detect them? How
