Adding gres usage to the accounting database
by Mark Dixon 13 Dec '24

13 Dec '24

Hello! Our jobs can ask for dedicated per-node disk space, e.g. "--gres=tmp:1G", where an ephemeral directory is managed by the site prolog/epilog and usage is capped using an xfs project quota. This works well, although we really need to look at job_container/tmpfs. I note that slurm already periodically polls jobs for their memory usage, which finds its way into the accounting database tres_usage fields. What would be really nice is if we could extend this polling so that we feed our xfs project quota utilisation into the accounting database, too: users get feedback on what their jobs need, and we notice people who ask for a fraction of a node and all of the disk space, but not use it. Slurm is famous for being extendible. Is there some sort of plugin hook someone can point me at to have a go with, or am I missing a simpler method, please? Thanks! Mark

TRES cpu vs tasks
by Miriam Olmi 10 Dec '24

10 Dec '24

Hi all, I cannot understand the true difference and definition of "core", "task" and "cpu" within the limits associated to a partition via the TRES variable of a QOS. More precisely I have 2 partitions defined as follows: PartitionName=lprod AllowGroups=ALL AllowAccounts=ALL AllowQos=ALL AllocNodes=ALL Default=NO QoS=lprod_part DefaultTime=NONE DisableRootJobs=NO ExclusiveUser=NO GraceTime=0 Hidden=NO MaxNodes=UNLIMITED MaxTime=1-00:00:00 MinNodes=0 LLN=NO MaxCPUsPerNode=UNLIMITED MaxCPUsPerSocket=UNLIMITED Nodes=r037c01s[01-12] PriorityJobFactor=1 PriorityTier=1 RootOnly=NO ReqResv=NO OverSubscribe=NO OverTimeLimit=NONE PreemptMode=OFF State=UP TotalCPUs=432 TotalNodes=12 SelectTypeParameters=NONE JobDefaults=(null) DefMemPerNode=UNLIMITED MaxMemPerNode=UNLIMITED TRES=cpu=432,mem=12M,node=12,billing=432 PartitionName=bprod AllowGroups=ALL AllowAccounts=ALL AllowQos=ALL AllocNodes=ALL Default=NO QoS=bprod_part DefaultTime=NONE DisableRootJobs=NO ExclusiveUser=NO GraceTime=0 Hidden=NO MaxNodes=UNLIMITED MaxTime=1-00:00:00 MinNodes=0 LLN=NO MaxCPUsPerNode=UNLIMITED MaxCPUsPerSocket=UNLIMITED Nodes=r037c01s[01-12] PriorityJobFactor=1 PriorityTier=1 RootOnly=NO ReqResv=NO OverSubscribe=NO OverTimeLimit=NONE PreemptMode=OFF State=UP TotalCPUs=432 TotalNodes=12 SelectTypeParameters=NONE JobDefaults=(null) DefMemPerNode=UNLIMITED MaxMemPerNode=UNLIMITED TRES=cpu=432,mem=12M,node=12,billing=432 with the two qos defined as: Name Priority GraceTime PreemptMode UsageFactor MaxJobsPU MaxSubmitPU MaxTRES MinTRES Flags -------------------- ---------- ---------- ----------- ----------- --------- ----------- -------------------- -------------------- -------------------------------------------------- lprod_part 0 00:00:00 cluster 1.000000 100 120 cpu=32,mem=366G cpu=1 DenyOnLimit,PartitionMaxNodes,PartitionMinNodes bprod_part 0 00:00:00 cluster 1.000000 100 120 cpu=64,mem=366G cpu=33 DenyOnLimit,OverPartQOS If I try to submit a job on the lprod partition with the directives: #SBATCH --nodes=12 #SBATCH --ntasks-per-node=1 the job is executed correctly while it is not executed if submitted on the bprod partition due to the error: sbatch: error: QOSMinCpuNotSatisfied sbatch: error: Batch job submission failed: Job violates accounting/QOS policy (job submit limit, user's size and/or time limits) I understand that this is related to the limit of cpu associated to the partition via the qos: lprod->[1-32]cpus, bprod->[33-64]cpus but I would like to have a more proper explanation since the options I am using are not referring to "cpu" but to "tasks" and I could not find a proper definition of "cpu" in the framework of the TRES. Many thanks in advance. Best, Miriam

error and output files
by michaelmorgan937＠gmail.com 09 Dec '24

09 Dec '24

Hi all, I have a program (for example x.x). When I run it as "x.x -I input -o output", I will get an "output" file, as well as output and error files from slurm. However, all the content of slurm output file is in the "output" file (and there are some extra content), so it is a waste to print the slurm output. Is it possible to set directives so that slurm only print error file? Thank you very much. Michael Morgan

Why is my job killed when ResumeTimeout is reached instead of it being requeued?
by Xaver Stiensmeier 09 Dec '24

09 Dec '24

Dear Slurm-user list, when a job fails because the node startup fails (cloud scheduling), the job should be re-queued: Resume Timeout Maximum time permitted (in seconds) between when a node resume request is issued and when the node is actually available for use. Nodes which fail to respond in this time frame will be marked DOWN and the jobs scheduled on the node requeued. however, instead of requeuing the job, it is killed. [2024-11-18T10:41:52.003] node bibigrid-worker-wubqboa1z2kkgx0-0 not resumed by ResumeTimeout(1200) - marking down and power_save [2024-11-18T10:41:52.003] Killing JobId=1 on failed node bibigrid-worker-wubqboa1z2kkgx0-0 [2024-11-18T10:41:52.046] update_node: node bibigrid-worker-wubqboa1z2kkgx0-0 reason set to: FailedStartup [2024-11-18T10:41:52.046] power down request repeating for node bibigrid-worker-wubqboa1z2kkgx0-0 Our ResumeProgram does not change the state of the underlying workers, I think we should set the nodes to DOWN explicitly if the startup fails given: *ResumeProgram* is unable to restore a node to service with a responding slurmd and an updated BootTime, it should set the node state to DOWN, which will result in a requeue of any job associated with the node - this will happen automatically if the node doesn't register within ResumeTimeout but in any case as we can see in the log the job should be requeued based on it reaching the ResumeTimeout alone. I am unsure why that is not happening. The power down request is sent by the ResumeFailProgram. We have SlurmctldParameters=idle_on_node_suspend activated, but that shouldn't affect Resume, I guess.

Newbie here, I'm trying to send myself an email notification with a custom body/subject for notification of important events. Is this possible? I've tried a few things in the script below. Thanks in advance and apologies if this is not how this listing works! - Daniel ---- Script ---- .... #SBATCH --mail-user= example(a)example.example #SBATCH --export=ALL #SBATCH --mail-type=ALL # Both of these work which mail which mailx EMAIL="example(a)example.example" # Attempt 1 echo "Test email body" | mail -s "Test Subject" "$EMAIL" # Attempt 2 mail -s "hello" "$EMAIL" <<EOF hello world EOF # Attempt 3 echo "Specific Information" | mail -s "SLURM Job information" $EMAIL ---- End ----
