RTFM ? From: John Hearns [mailto:john.hea...@xma.co.uk] Sent: 16 February 2017 15:13 To: slurm-dev <slurm-dev@schedmd.com> Subject: [slurm-dev] Slurm with sssd - limits help please Looks like there are others out there using slurm with sssd authentication, based on a quick mailing list search. Forgive me if I have not understood something here. On the cluster I am configuring at the moment, looking at the slurm daemon on the compute nodes it has the max locked memory limit set to unlimited. /etc/security/limits.conf has soft and hard max locked memory set to unlimited for all users. I tried to run an MPI job and got the familiar warning that there was not enough locked memory available.. Looked at /etc/security/limits.conf as I have been bitten by that one before… I log in using an srun and sure enough: max locked memory (kbytes, -l) 64 It looks to me like the limits are being inherited from the /usr/sbin/sssd daemon In return this is started by systemd…. (cue dark clouds, the howling of a wolf and the sound of thunder off-stage) At the moment I am looking at how to increase limits with systemd Please, someone tell me I’m an idiot and there is an easy way to do this. I weep though – is system really losing us the dependable and well known ways of doing things with limits.conf ??
