Force a refresh for sreport
by Jackson, Gary L. 10 Feb '25

10 Feb '25

As I understand it, slurmdbd will compile statistics for sreport once an hour. Is there any way I can force that to happen immediately? Restarting slurmdbd doesn’t seem to do anything. I don’t want to use this for anything operational. Just testing. -- Gary

jobs getting stuck in CG
by Ricardo Román-Brenes 10 Feb '25

10 Feb '25

Hello everyone. I have a cluster composed of 16 nodes, with 4 of them having GPUs with no particular configuration to manage them. The filesystem is gluster, authentication via slapd/munge. My problem is that very frequently, let's say at least a job daily, gets stuck in CG. I have no idea why this happens. Manually killing the slurmstep process releases the node but this is in no way a manageable solution. Has anyone experienced this (and fixed it?) Thank you. -Ricardo

MemSpecLimit Error
by Chase Schuette 07 Feb '25

07 Feb '25

After a Bright Computing/Base Command update. I'm encountering a slurm.conf error as seen below. I tried removing the MemSpecLimit parameter from the node names but the changes don't seem to be taking affect. Even after restarting slurmd across compute nodes and restarting slurmctld on the head node. I'm also suspicious of the RealMemory being set to zero. Any insight? Open to suggestions. Thanks ahead of time! sbatch: error: NodeNames=ch3lahpccn[001-032] MemSpecLimit=0 is invalid, reset to 0 sbatch: error: NodeNames=ch3lahpcgpu1 MemSpecLimit=0 is invalid, reset to 0 sbatch: error: Memory specification can not be satisfied sbatch: error: Batch job submission failed: Requested node configuration is not available Caterpillar: Confidential Green

Issue running slurm commands as normal account but work as root.
by Kent L. Hanson 05 Feb '25

05 Feb '25

Hello all! I have an odd question. On my headnode, also my login nodes, I can ping my outside network and inside network using any DNS name I choose. It is dual homed. When I run squeue, sinfo, or any slurm command as my regular account I get the below error. I can run srun, squeue, sinfo, or any slurm command and it works as expected. Does anyone know what is going on? I feel like this is a permissions issue on something. On the compute nodes I have no problem running slurm commands as my regular account or root. Everything works well on my compute nodes. Error: [user.name@headnode ~]$ squeue squeue: error: resolve_ctls_from_dns_srv: res_nsearch error: Hostname lookup failure squeue: error: fetch_config: DNS SRV lookup failed squeue: error: _establish_config_source: failed to fetch config squeue: fatal: Could not establish a configuration source Thanks!

Submit multiple jobs odd info on squeue

Hi, I submit 2 or more jobs to test the scheduler and how it is handling multiple job requests and overall info. Now I submit two or more jobs I get the following odd output: [vitorio@dev35 verif_dev]$ squeue JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON) 2 sim run.sh vitorio PD 0:00 1 (InvalidAccount) 1 sim run.sh vitorio R 15:35 1 dev35 [vitorio@dev35 verif_dev]$ ^C What about this InvalidAccount ?? All subsequent jobs show up like that Regards, Vitorio

System limits propagation
by Fatih Ertinaz 31 Jan '25

31 Jan '25

Hi everyone, I saw similar discussions in the archives, however I could not see a clear explanation therefore decided to open up a new thread. The problem I have is that default ulimits defined in the compute node OS image are overridden by Slurm and somehow changes in slurm.conf does not resolve the problem. This is specifically about max memory size, but the same issue applies to stack size and user processes as well. From the head node or from one of the compute nodes if I bypass slurm: max memory size (kbytes, -m) unlimited But going through salloc / sbatch it becomes: max memory size (kbytes, -m) 1024 As an initial attempt I tried setting `PropagateResourceLimitsExcept=NONE` but it didn't help. Then I tried `PropagateResourceLimits=ALL` also with no luck. So in theory PropagateResourceLimits should propagate all limits, but I'm not sure if that's really the case. I'm open to suggestions, Fatih Ertinaz Note: Slurm version is 24.05.1 OS is SLES SP5
