Hi David, I actually don't know much about cgroups, and I don't have a single-node cluster.
Here are some cgroup-related settings from my regular Ubuntu 18.04 cluster, running SLURM 18.08.7 root@cb-admin:~# cat /etc/slurm/slurm.conf | grep -i cgr ProctrackType=proctrack/cgroup TaskPlugin=task/cgroup JobAcctGatherType=jobacct_gather/cgroup root@cb-admin:~# cat /etc/slurm/cgroup.conf CgroupAutomount=yes CgroupReleaseAgentDir="/etc/slurm/cgroup" ConstrainCores=yes ConstrainDevices=yes ConstrainRAMSpace=yes #TaskAffinity=yes I just copied those from somewhere, so I'm not sure how helpful they are to you. I think there were cgroups-related changes between slurm 17/18/19. I also think systemd is intimately involved, but I've never looked closely. e.g. https://bugs.schedmd.com/show_bug.cgi?id=5292 https://groups.google.com/forum/#!topic/slurm-users/3vZUoZ_DXJI Regards, Alex On Thu, Aug 22, 2019 at 8:57 AM David da Silva Pires < david.pi...@butantan.gov.br> wrote: > Hi Alex. > > Thank you very much for taking you time to help me. > > Here are the versions of the listed software: > > Distro: Ubuntu Server 18.04 LTS > Kernel: 4.15.0-59-generic x86_64 GNU/Linux > systemd: 237-3ubuntu10.25 > SLURM: 17.11.2-1build1 > > So, you guessed right, Alex. > > Do you think I should compile the last SLURM version instead of using the > default one from Ubuntu packages? > > Is there anything wrong in my configuration? > > By the way, the absolute path of the last two configuration files are: > > /etc/slurm-llnl/slurm.conf > /etc/slurm-llnl/cgroup.conf > > Best regards. > > -- > David da Silva Pires >
