title: How to run a parallel python script
body: <p>I am using a code from VAST <a href="https://vast.readthedocs.io/en/latest/VoidFinder_examples.html" rel="nofollow noreferrer">https://vast.readthedocs.io/en/latest/VoidFinder_examples.html</a> called Gadget_VoidFinder_periodic.py. This code is supposedly parallelized. I have set up the parameter num_cpu = 54 as I am running the code in a server. When I check how many cores the code is using, I see it's using all of them but not the 100% of them. How can I change this?</p>
  <p>I write python Gadget_VoidFinder_periodic.py in order to run the script in the server</p>
