Do Multiple Python Programs Use Different Cpu Cores?

I have a question regarding Python and load balancing. Consider a virtual machine with 16 virtual cpu cores and single Python Rest-Service wrapped in Docker.

How to limit CPU utilization caused by docker commands in python

I am writting a python program (not container) that controls docker containers using docker commands wrapped with a python subprocess so that I can manipulate containers programatically. One thing I noticed is that the CPU usage reaches 100% when I make a call to subprocess.Popen(["docker", "save", "-o", "image_file.tar", image_id] to save a docker image. As […]
