Sure, in CAE CalculiX runs automatically on all cores.

os.environ['OMP_NUM_THREADS'] = str(os.cpu_count()) # enable multithreading

Yes, I got it. However, I am using for windows "CalculiX Advanced Environment v0.8.0" from "latest release". Can you please tell me where I could find the similar setting?

In the same file, if you're using the source code version.
/src/model/job.py, line 171:
os.environ['OMP_NUM_THREADS'] = str(os.cpu_count()) # enable multithreading

Binary version has enabled multi-threading, and it can't be switched off.
