Benjamin Mahler commented on MESOS-888:
---------------------------------------
You do not need to disable hyperthreading for the slave to report the real
number of cores, if you provide a {{--resources}} flag, the slave will report
the specified number of cpus, rather than trying to determine the number of
cpus at run-time.
> option on slave to recognize only real cores and not hyperthreaded cores

> Key: MESOS-888
> URL: https://issues.apache.org/jira/browse/MESOS-888
> Project: Mesos
> Issue Type: Improvement
> Components: master
> 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.
