Closed guanchenY closed 1 year ago

guanchenY commented 1 year ago

I want to know that how to use nodeController.py,cpu_utils.py. Or to put it another way, when do I use these files？Thank you !

jovans2 commented 1 year ago

Hello, 1) cpu_utils.py is used to measure the CPU utilization of a container with "docker stats" command 2) nodeController.py is used to assign cores on your servers across co-located containers -- based on the needs of these containers, node controller decides how many CPUs are needed for each of them. Hope this helps, if not, let me know what else is confusing. Thank you!

I have some questions about the use of nodeController.py.

The README mentions two experiments, python3 knative_all.py and python3 run-all.py. One runs on the Knative platform and the other experiment actually evaluates the performance of runner.py in a container.

None of the experiments seem to involve NodeController.py. So, how is the updateThread in runner.py actually activated? From the code, it looks like a thread is listening on port 5500. Since I haven't observed the running of NodeController.py, I can't tell where requests to port 5500 are coming from.

I have previously submitted another related Issue, but I still have questions about the use of NodeController.py.

I would appreciate any response. Thanks
