Is it possible to force a task to have a particular thread id?

[nilshg]

Have you read this recent discussion and the links therein?

Why has simple threading using `threadid` become so complex in v1.12...?

The documentation for both OhMyThreads.jl and ChunkSplitters.jl do a great job at explaining how “simple” multithreading can work. As an example, using ChunkSplitters.jl, you could do: # setup n = Threads.nthreads() ds = mutable_datastructure() dss = [deepcopy(ds) for _ in 1:n] outputs = zeros(length(some_iterable)) Threads.@threads for (i, c) in enumerate(chunks(some_iterable; n=n)) local ds = dss[i] for j in c outputs[j] = computation!(ds, j) end end

I’ve not looked into this deeply, but the general gist I get from these conversations is that you shouldn’t rely on the thread id for anything.
