@threads :dynamic expr

[serpenttom]

There is an ## Example for @threads in threadingconstructs.jl. My Julia is v1.7.3. The first example, @threads :static expr runs in success.

6.021147 seconds (62.77 k allocations: 3.639 MiB, 1.13% compilation time)

However, the second example fails.

ERROR: LoadError: ArgumentError: unsupported schedule argument in @threads
Stacktrace:
[1] var"@threads"(source::LineNumberNode, module::Module, args::Vararg{Any})
@ Base.Threads .\threadingconstructs.jl:137
in expression starting at REPL[4]:3

How can I solve this ERROR.

Thank you very much.

I have tried in v1.8.0. and both example succeed. It may be owing to the version of Julia.

I'm glad you figured it out! :dynamic threads are a feature that is not present in 1.7 or earlier versions of Julia.

For future reference, this sort of question is best directed to the #hepdesk slack channel or the Julia discourse.
