10288 :: Multithread with js target

• Traveler (orginal) [2023-06-20T19:04:26+02:00] view original

  Hi, Is there a way to get the thread pool working for a js target? It seems to be ignored when compiling to js.

  This is not possible, as JavaScript runs in a single thread.

  Some runtimes, such as node.js, provide threading in some ways, but it's not inherent to the language so to use it you need to write bindings to specific functionality these runtimes provide.

  There is no convenient library for doing multithreading with workers in Nim right now. As for -d:threads, that's simply not going to work since JS doesn't have threads built into the language.

  perhaps not when targeting the browser

  but targeting nodejs we should be able to manage worker threads

  There is some kind a new JS standard around multithreading, (Dedicated-/Shared-/Service)-workers and data-exchange via shared-memory. AFAIK Lars T. Hansen did some groundwork for the standard [ https://hacks.mozilla.org/2016/05/a-taste-of-javascripts-new-parallel-primitives/ ]. Since it inception in 2017 these new features were heavily exploited and many browser-vendors decided to deactivate those features quickly. I doubt that a mapping from Nims idioms into the browser-environment can easily be done..
