[jira] [Created] (MESOS-2700) Determine CFS behavior with biased cpu.shares subtrees

Ian Downes created MESOS-2700:
---------------------------------

             Summary: Determine CFS behavior with biased cpu.shares subtrees
                 Key: MESOS-2700
                 URL: https://issues.apache.org/jira/browse/MESOS-2700
             Project: Mesos
          Issue Type: Task
          Components: isolation
    Affects Versions: 0.22.0
            Reporter: Ian Downes


See this [ticket|https://issues.apache.org/jira/browse/MESOS-2652] for context.

* Understand the relationship between cpu.shares and CFS quota.
* Determine range of possible bias splits
* Determine how to achieve bias, e.g., should 20:1 be 20480:1024 or ~1024:50
* Rigorous testing of behavior with varying loads, particularly the combination of latency sensitive loads for high biased tasks (non-revokable), and cpu intensive loads for the low biased tasks (revokable).
* Discover any performance edge cases?
