> Currently the usage callback in the Nvidia GPU isolator is unimplemented:
> {noformat}
> src/slave/containerizer/mesos/isolators/cgroups/devices/gpus/nvidia.cpp
> {noformat}
> It should use functionality from NVML to gather the current GPU usage and add it to a ResourceStatistics object. It is still an open question as to exactly what information we want to expose here (power, memory consumption, current load, etc.). Whatever we decide on should be standard across different GPU types, different GPU vendors, etc.
