@threads (incorrectly?) using :interactive thread pool #50438
Comments
|
I believe it is using the same pool as the current task, which is interactive for a REPL input. I do think it's good to use the current pool, but maybe that shouldn't extend to the interactive pool? |

My intuition is that
Threads.@threadsshould always be using the default thread pool, even when run from the REPL withoutThreads.@spawn, but if I run the following, I can see Julia only using a single thread, which I presume is from the interactive pool.If I start julia with
-t8, it uses all 8 cores because then there are no interactive threads, so I guess it decides to use the default pool instead. Starting julia with-t8,4allows it to use 4 threads, so it clearly seems to be using interactive threads in that case.If this is really the intended behavior, I think the docs should be more clear about that. But I think it would make more sense for it to always use the default pool.
