Go's goroutines highlighted the difference: concurrency is doing many things at once, while parallelism is doing many things at the same time.AsyncIO handles concurrency well for I/O, but CPU-bound tasks need parallelism. Python uses AsyncIO for concurrency, and ProcessPoolExecutor for parallelism, distributing work across CPU cores.Process communication is harder than thread communication. AsyncIO's task cancellation differs from ProcessPoolExecutor's, requiring workarounds like event objects for reliable cancellation and shutdown.Essentially, ProcessPoolExecutor enables parallelism for CPU-bound tasks, scaling them across multiple cores, while AsyncIO handles I/O concurrently.<a href="https://hachyderm.io/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> <a href="https://hachyderm.io/tags/asyncio" class="mention hashtag" rel="nofollow noopener" target="_blank">#asyncio</a> <a href="https://hachyderm.io/tags/concurrency" class="mention hashtag" rel="nofollow noopener" target="_blank">#concurrency</a> <a href="https://hachyderm.io/tags/parallelism" class="mention hashtag" rel="nofollow noopener" target="_blank">#parallelism</a> <a href="https://hachyderm.io/tags/multiprocessing" class="mention hashtag" rel="nofollow noopener" target="_blank">#multiprocessing</a> <a href="https://hachyderm.io/tags/opentowork" class="mention hashtag" rel="nofollow noopener" target="_blank">#opentowork</a> <a href="https://hachyderm.io/tags/getfedihired" class="mention hashtag" rel="nofollow noopener" target="_blank">#getfedihired</a> <a href="https://hachyderm.io/tags/fedihire" class="mention hashtag" rel="nofollow noopener" target="_blank">#fedihire</a> <a href="https://hachyderm.io/tags/opentowork" class="mention hashtag" rel="nofollow noopener" target="_blank">#opentowork</a>

Ivan Enderlin 🦀<a href="https://fosstodon.org/tags/weld" class="mention hashtag" rel="nofollow noopener" target="_blank">#weld</a>To be fast, weld needs to link objects concurrently & simultaneously. A few days ago, I’ve implemented a simple `ThreadPool` type, in the new `weld-scheduler` crate, <a href="https://github.com/Hywan/weld/blob/ea792c808887306acc6985bd71910fc35051a530/crates/scheduler/src/lib.rs" rel="nofollow noopener" translate="no" target="_blank">https://github.com/Hywan/weld/blob/ea792c808887306acc6985bd71910fc35051a530/crates/scheduler/src/lib.rs</a>.It’s able to send `Future`s on various threads where async workers execute them.It’s done with smol, a light & flexible set of crates to implement custom async runtimes, <a href="https://github.com/smol-rs/smol" rel="nofollow noopener" translate="no" target="_blank">https://github.com/smol-rs/smol</a>.Next step: “Linker Strategy” to link things for real!<a href="https://fosstodon.org/tags/RustLang" class="mention hashtag" rel="nofollow noopener" target="_blank">#RustLang</a> <a href="https://fosstodon.org/tags/parallelism" class="mention hashtag" rel="nofollow noopener" target="_blank">#parallelism</a> <a href="https://fosstodon.org/tags/concurrency" class="mention hashtag" rel="nofollow noopener" target="_blank">#concurrency</a> <a href="https://fosstodon.org/tags/thread" class="mention hashtag" rel="nofollow noopener" target="_blank">#thread</a>
