I have just found JULIA_NUM_THREADS in the documentation, and I wonder if Julia is already doing a good job on picking up the number of CPU cores on my laptop. Is there a command to find the number of threads available?
Threads.nthreads(). It doesn’t add threads by default, but Juno does.
I tried setting the variable
JULIA_NUM_THREADS on my
.juliarc.jl file but it doesn’t affect
Threads.nthreads(). Is it already implemented?
That won’t work.
JULIA_NUM_THREADS is supposed to be an environment variable set before Julia is opened.
Thank you all, I have the variable set on my
.bashrc, and it works now. Though I think this should be widely spread to other Julians, I’d have set this variable a long time ago.
No please don’t. It is highly experimental.
What is not highly experimental in Julia?
Well, there are the kind of code that is expected to work and there are features that aren’t.
