Topic: The currently implementation for threading

view this post on Zulip Dennis Zhang (Jun 20 2024 at 19:13):

Hi community,

Is there any implementation for threading in Wasmtime? I'm looking for functionality similar to fork or thread creation as seen in traditional operating systems. Specifically, I'm interested in:

  1. Thread Creation: How can I create and manage threads within a Wasmtime instance? Is there a standard API or library that provides threading support?

  2. Concurrency: What are the best practices for handling concurrent execution in Wasmtime? Are there any examples or documentation on how to implement concurrency effectively?

  3. Shared State: How can I share state between threads? Are there any built-in mechanisms or patterns recommended for shared memory or message passing between threads in Wasmtime?

  4. Synchronization: What synchronization primitives are available (e.g., mutexes, semaphores) for managing access to shared resources?

Any guidance, examples, or references to relevant documentation would be greatly appreciated.

Thanks in advance!

wasi-threads is supported by Wasmtime. It has a hard dependency on wasip1 however and doesn't work with wasip2.
