<p class="MsoNormal">As for the cgroup_allowed_devices.conf file, I have this file stubbed but empty. In 17.02 slurm started fine without this file (as far as I remember) and it being empty doesn’t appear to actually impact anything… device availability remains
the same. Based on the behavior explained in [0] I don’t expect this file to impact specific GPU containment. <o:p></o:p></p>
