>                 Key: MESOS-888
>                 URL: https://issues.apache.org/jira/browse/MESOS-888
>             Project: Mesos
>          Issue Type: Improvement
>          Components: slave
>    Affects Versions: 0.15.0
>            Reporter: Michael Shamberger
>              Labels: core, slave
>
> A service provider cannot sell a hyperthreaded core as a real core.  Currently it would require disabling hyperthreading on the physical server for mesos to report the actual number of cores.
> For example,
> My haswell box is showing 8 core but really has 4 real cores.
