----------------------------------
Summary: Account for thermos executor overhead in reported CPU
usage to user
Key: AURORA-1766
URL: https://issues.apache.org/jira/browse/AURORA-1766
Project: Aurora
Issue Type: Story
Components: Scheduler
Reporter: Rick Mangi
The default .25 CPU overhead taken for thermos can be hugely impactful on
clusters with many tasks and it's not reported to the user in the web UI.
Ideally the resources used by the cluster should be reported accurately. We ran
into a case where we could not launch jobs even though we thought we had plenty
of free cores.
Alternatively, the thermos overhead could be removed completely. I think it's
confusing personally.
