I wish to restrict access to using a GPU (in terms of reserving memory on it) for certain users on a jointly used workstation. So if a user tries to access the GPU on SSH, for example via CUDA, that request would be denied. Any ideas where to start looking for that?

Thanks in advance!

  • Add a group `cuda` to your Ubuntu, then set `750` permissions on the `/dev/nvidia*` devices and change the group ownership to `cuda`. Add those users that are granted to use the GPU to the group `cuda`. There are also driver parameters that do this for you during loading the nvidia driver. ( `NVreg_DeviceFileGID` and `NVreg_DeviceFileMode` ). – Thomas Mar 16 '17 at 11:07
  • @Thomas thank you very much, that's awesome! If you convert your comment into an answer, I could accept it... :) – jmaxx Mar 20 '17 at 02:08
