Kevin Klues commented on MESOS-5717:
------------------------------------
We noticed this error in the documentation and are fixing it now:
{noformat}
if (devicesIsolator == tokens.end()) {
return Error("The 'cgroups/devices' isolator must be enabled in"
" order to use the gpu/devices isolator");
}
{noformat}
The error message should read "The 'cgroups/devices' isolator must be enabled
in order to use the gpu/nvidia isolator".
We also noticed an inconsistency in the documentation for the `--isolator`
flag. This fix has already been committed:

Removed stale flag references to the GPU isolator.

Hopefully this clears things up.
> Can't autodiscovery GPU resources without '--enable-nvidia-gpu-support' and

> Key: MESOS-5717
> URL: https://issues.apache.org/jira/browse/MESOS-5717
> Project: Mesos
> Issue Type: Bug
> Environment: RHEL 7.2
> Reporter: Sunzhe
> Assignee: Kevin Klues
> Labels: gpu
> Fix For: 1.0.0
>
>
> Prerequisite: In MESOS\-5257 "By default, with no '\-\-nvidia_gpu_devices'
> flag or `gpus` resources flag, the new auto-discovery will simply enumerate
> all of the GPUs on the system" and in MESOS\-5630 "removes this
> flag(\-\-enable-nvidia-gpu-support) and enables this support for all builds
> on Linux."
> So, I '../configure' without any flag, and start agent without
> '\-\-resources' or '\-\-nvidia_gpu_devices' , but can not discovery GPU
> resources, and I also start agent with '\-\-resources' and
> '\-\-nvidia_gpu_devices' , it also does not work.
> I'm sure the NVIDIA GPUs on my machines are OK, because with
> '\-\-enable-nvidia-gpu-support' when './configure' and with '\-\-resources',
> '\-\-nvidia_gpu_devices' when starting agents it works well.
