I am curious if it is a hython thing or a Deadline one:
When Deadline triggered a render, it uses hython, on my side I see the jobs only using 16 threads versus my full 128 one.
Is there a way to change that cap limit system wide via ENV like HOUDINI_MAXTHREADS ? But I am not sure that ENV is for hython specifically

Thank you for you responses if any

From `hython --help`:
"""
-j arg : sets HOUDINI_MAXTHREADS to the given value;
arg is the max number of threads
"""
Which implies that HOUDINI_MAXTHREADS env var works for hython as well.

You can check the number of threads from inside hython using `hou.maxThreads()`.
Also there's `hou.setMaxThreads(max_threads)`, but according to docs, there are some limitations.
