             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.
