I think it is a great way to handle GPU permissions, and I sent your method of managing GPU permissions to a GPU & clustering discussion list.
However, I assumed that you were using multiple queue instances per node, and each queue logically owns the GPU. Was my assumption correct? -Ron ----- Original Message ----- From: William Hay <[email protected]> To: Rayson Ho <[email protected]> Cc: "[email protected]" <[email protected]> Sent: Tuesday, May 22, 2012 2:02 PM Subject: Re: [gridengine users] cgroups Integration in OGS/GE 2011.11 update 1 On 22 May 2012 18:21, Rayson Ho <[email protected]> wrote: > Hi William, > > Can you give me an example of this use case?? Well currently we have our prolog chgrp the appropriate number of /dev/nvidia? files to the group associated with the job thereby controlling access to GPUs. I'm currently setting up $TMPDIR as a separate tmpfs file system for each job and am chgrping that to the job's associated group in the process. In general access control for anything that looks like a file and under unix it is alleged "everything is a file".
