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!

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

Behavior of 'afterok' in cloud clusters
by Thompson, Hoot (GSFC-606.0)[ADNET SYSTEMS INC] 30 Jan '25

30 Jan '25

The behavior of slurm jobs using the ‘afterok’ dependency seems to have issues with ephemeral compute nodes such as those in a cloud cluster. If the specified jobid dependency is associated with a compute node that has already spun down then a subsequent job that requires successful completion of the prior job will fail with a “Job dependency problem”. This occurs when the subsequent job is tied to a node that must spin up before beginning execution. This phenomenon does not occur if the ‘afterany’ dependency is used. It seems that job completion status is retained when a node is spun down but no information as to whether the job was successfully executed is saved. There are perhaps other scenarios that coud cause the same issue. Has anyone else witnessed this problem? How can it be avoided? afterany This job can begin execution after the specified jobs have terminated. aftercorr A task of this job array can begin execution after the corresponding task ID in the specified job has completed successfully afternotok This job can begin execution after the specified jobs have terminated in some failed state afterok This job can begin execution after the specified jobs have successfully executed

Optimizing CPU allocation in Slurm with hyperthreading enabled
by Guillaume COCHARD 30 Jan '25

30 Jan '25

Hello, The Slurm documentation states that "The default allocation method within a node is cyclic allocation (allocate available CPUs in a round-robin fashion across the sockets within a node)." In our case, we are using hyperthreading, which means that if two jobs requesting one CPU each arrive at the same time on an empty node, they will be assigned to the two threads of the same physical core. To improve performance, we would like Slurm to allocate CPUs (in our case, threads) in a way that prioritizes using one thread per physical core first, and only once all cores are occupied, assign the second thread of each core. This would be similar to the Least Loaded Node (LLN) approach, but instead of distributing jobs across nodes, it would distribute them across physical cores (Least Loaded Core). We do not want to disable hyperthreading; we simply want to optimize core usage when a machine is not fully loaded. We also want this to be a cluster-wide setting, and not a user and/or job setting. Our current slurm.conf contains: ConstrainCores = no SelectType = select/cons_tres SelectTypeParameters = CR_CPU_MEMORY And our cgroup.conf contains: ConstrainDevices=yes ConstrainCores=yes Does anyone know how to achieve this? Thanks, Guillaume

Cloud elastic help
by mark.w.moorcroft＠ama-inc.com 29 Jan '25

I have a new Slurm setup in AWS gov cloud that is not quite working. I will list a few factoids and maybe someone can suggest where to look next. The Troubleshooting page really has nothing relevant for elastic cloud deployments. The nodes are getting set to DOWN+CLOUD+POWERED_DOWN. Running a job does not launch a node in this state. I can force the nodes to launch with scontrol POWER_UP. The jobs will claim to run, then re-queue, but never complete. When the nodes boot I see them appear in slurmctl, but it soon reports connection lost. The node slurmd claims to be healthy, but the controller eventually just terminates them. You can ping in both directions with the hostnames. I've done 4 clusters. The first was torque/maui and the rest were slurm, but all were bare metal. This is my first attempt at cloud. We have ITAR data, so I can't use Amazon Parallel Computing because it is not offered in GovCloud. https://cluster-in-the-cloud.readthedocs.io/en/latest/running.html I had to fork this project because so much is obsolete, but it's mostly working for me now. https://github.com/mntbighker [root@mgmt ~]# journalctl -fu slurmctld Jan 29 19:16:15 mgmt.many-antelope.citc.local slurmctld[3403]: slurmctld: debug: sched/backfill: _attempt_backfill: 1 jobs to backfill Jan 29 19:16:45 mgmt.many-antelope.citc.local slurmctld[3403]: slurmctld: debug: Updating partition uid access list Jan 29 19:16:45 mgmt.many-antelope.citc.local slurmctld[3403]: slurmctld: debug: purge_old_job: job file deletion is falling behind, 1 left to remove Jan 29 19:16:45 mgmt.many-antelope.citc.local slurmctld[3403]: slurmctld: debug: sched: Running job scheduler for full queue.

Adding a permanent node Feature to slurm in AWS parallelcluster
by luigi＠scorzato.it 28 Jan '25

28 Jan '25

I need to add a node Feature to my SLURM AWS parallel-cluster I understand from here: https://groups.google.com/g/slurm-users/c/LgL6hq3XxzE that to add a node feature permanently I have to edit slurm.conf, because the effects of the command: scontrol update NodeName=[node(s)] AvailableFeatures=[comma separated list of features] will not persist after restart (besides, I could not find how to ADD a feature without deleting the existing AvailableFeatures). However, AWS parallelcluster slurm.conf already includes files that contain lines like: NodeName=nn77[1-100] CPUs=2 RealMemory=186777 State=CLOUD Feature=dynamic,g4dn.large,gpu Weight=1000 Gres=gpu:t4:1 which is automatically generated and should not be edited. What is the recommended way to add a feature without breaking the parallelcluster set up? My I put somewhere something like NodeName=nn77[1-100] Feature+=cascadelake ? thank you!

Automate job lmod environment setup based on node
by Daniel UB 27 Jan '25

27 Jan '25

Greetings ! We're using Slurm 23.11.8 in a small cluster . The control node shares via NFS the directory /clusterprograms with the compute nodes (using the same name as mountpoint) to provide access to available software. The users are instructed to use lmod<https://lmod.readthedocs.io/en/latest/060_locating.html> (module load/avail/purge) to setup their job's runtime environment. We have the software and modules at /clusterprograms distributed like this: /clusterprograms/ ├── common ├── gpu/ │ ├── cuda8/ │ └── cuda10/ └── cpu/ ├── intel/ └── amd/ We configured the /etc/profile.d/ directory on each node so ,when we access them directly (via ssh) the paths used by module (MODULEPATH) are only these: * /home/<user>/modulefiles * /clusterprograms/common/modules * /clusterprograms/<processor vendor or cuda version>/modules The exception is the control/login node, which only has /home/<user>/modulefiles and /clusterprograms/common/modules The issue we have now is this: We are looking for a safe and practical way to automate the reconfiguration of MODULEPATH<https://lmod.readthedocs.io/en/latest/077_ref_counting.html> in the compute nodes when a job is submitted. For now, the only method that is "working" is the following TaskProlog script, but it forces the users to load the modules inside the scripts that may be called by srun steps, rather than being able to load them in the job base step: #!/bin/bash if [[ -n "${SLURM_JOB_CONSTRAINTS}" ]]; then echo "export ORIGINAL_MPATH=${MODULEPATH}" IFS=',' read -ra JOB_ARCH_CONSTRAINTS <<< "$SLURM_JOB_CONSTRAINTS" for constraint in "${JOB_ARCH_CONSTRAINTS[@]}"; do case "${constraint}" in cuda*) echo "export MODULEPATH=/clusterprograms/gpu/${constraint}:${MODULEPATH}" ;; intel-*) echo "export MODULEPATH=/clusterprograms/cpu/intel/${constraint}:${MODULEPATH}" ;; amd-*) echo "export MODULEPATH=/clusterprograms/cpu/amd/${constraint}:${MODULEPATH}" ;; esac done fi Is there any better way to do this ? How is that it doesn't work if we use Prolog ? I tried using the --export option but it doesn't work, since the control node has MODULEPATH set via the main shell profiles.

Problems with slurmdbd on Ubuntu 24.04

Hello, Last weekend, I updated my server to ubuntu 24.04 and instead of using my own compiled version of slurm, I switched to the version (23.11.4) that comes with Ubuntu 24.04. Since then, I have been having problems with slurmdbd. I get the following error message: slurmdbd: error: issue making get_lineage procedure slurmdbd: accounting_storage/as_mysql: init: Accounting storage MYSQL plugin failed slurmdbd: debug2: wsrep_on=0 slurmdbd: error: Couldn't load specified plugin name for accounting_storage/mysql: Plugin init() callback failed slurmdbd: error: cannot create accounting_storage context for accounting_storage/mysql slurmdbd: fatal: Unable to initialize accounting_storage/mysql accounting storage plugin My /etc/slurm/slurmdbd.conf looks like this: AuthType=auth/munge DebugLevel=debug5 DbdHost=localhost DbdPort=3306 StorageLoc=slurm_acct_db StoragePass=<password> StorageType=accounting_storage/mysql StorageUser=slurm SlurmUser=admina PluginDir=/usr/lib/x86_64-linux-gnu/slurm-wlm ArchiveEvents=yes ArchiveJobs=yes ArchiveResvs=yes ArchiveSteps=no ArchiveSuspend=no ArchiveTXN=no ArchiveUsage=no AuthInfo=/var/run/munge/munge.socket.2 PurgeEventAfter=1month PurgeJobAfter=12month PurgeResvAfter=1month PurgeStepAfter=1month PurgeSuspendAfter=1month PurgeTXNAfter=12month PurgeUsageAfter=24month LogFile=/var/log/slurm/slurmdbd.log PidFile=/var/run/slurmdbd.pid NOTE: Removing the PluginDir directive makes no difference.

Re: Slurm "showpartitions" tool has been updated

Hi Robert, What's your version of Slurm? We run 24.05.5. The showpartitions tools compacts the list of nodenames using "scontrol show hostlistsorted <nodelist>". Can you please check your scontrol manual page if "hostlistsorted" is documented? Does the command work without -N?

Slurm "showpartitions" tool has been updated
by Ole Holm Nielsen 17 Jan '25

17 Jan '25

Dear Slurm users, The "showpartitions" tool prints a Slurm cluster partition status overview with 1 line per partition. Color coding helps locating under- or over-utilized partitions. The Slurm "showpartitions" tool has now been updated with a new "-N" flag which prints the nodename list for each partition. You can download this tool from https://github.com/OleHolmNielsen/Slurm_tools/tree/master/partitions If you have any issues or suggestions, please write to Ole.H.Nielsen(a)fysik.dtu.dk or open an issue on GitHub.

job_container/tmpfs and srun.
by Phill Harvey-Smith 17 Jan '25

17 Jan '25

Hi all, On our setup we are using job_container/tmpfs to give each job it's own temp space. Since our compute nodes have reasonably sized disks for tasks that do a lot of disk I/O on user's data we have asked users to copy their data to the local disk at the beginning of the task and (if needed) copy it back at the end. This saves lots of NFS thrashing slowing down both the task and the NFS servers. However some of our users are having problems with this, their initial sbatch script will create a temp directory in their private /tmp copy their data to it and then try to srun a program. The srun will fall over as it doesn't seem to have have access to the copied data. I suspect this is because the srun task is getting it's own private /tmp. So my question is, is there a way to have the srun task inherit the /tmp of the initial sbatch? I'll include a sample of the script our user is using below. If any further information is required please feel free to ask. Cheers. Phill. #!/usr/bin/bash #SBATCH --nodes 1 #SBATCH --ntasks-per-node=1 #SBATCH --cpus-per-task=1 #SBATCH --time=00:00:10 #SBATCH --mem-per-cpu=3999 #SBATCH --output=script_out.log #SBATCH --error=script_error.log # The above options puts the STDOUT and STDERR of sbatch in # log files prefixed with 'script_'. # Create a randomly-named directory under /tmp jobtmpdir=$(mktemp -d) # Register a function to try and cleanup in case of job failure cleanup_handler() { echo "Cleaning up ${jobtmpdir}" rm -rf ${jobtmpdir} } trap 'cleanup_handler' SIGTERM EXIT # Change working directory to this directory cd ${jobtmpdir} # Copy the executable and input files from # where the job was submitted to the temporary directory. cp ${SLURM_SUBMIT_DIR}/a.out . cp ${SLURM_SUBMIT_DIR}/input.txt . # Run the executable, handling the collection of stdout # and stderr ourselves by redirecting to file srun ./a.out 2> task_error.log > task_out.log # Copy output data back to the submit directory. cp output.txt ${SLURM_SUBMIT_DIR} cp task_out.log ${SLURM_SUBMIT_DIR} cp task_error.log ${SLURM_SUBMIT_DIR} # Cleanup cd ${SLURM_SUBMIT_DIR} cleanup_handler

Environment Variables per Queue
by Vitorio Cargnini 14 Jan '25

14 Jan '25

Hello, Can environment variables be set up based on a specific queue? How do I set up the environment variables for a given queue? Like we are deploying SLURM to control our jobs of simulation using VCS, and we don't want to make public the LM_LICENSE environment variable to all users. So we would like to set it on the queue once a job is started on that queue would have that environment variable. Regards, Vitorio

Discrepancy in TmpDisk values between scontrol and sinfo in Slurm24.05.3
by Gizo Nanava 11 Jan '25

11 Jan '25

There seems to be an issue with the TmpDisk value reporting in Slurm 24.05.3. While the correct value is displayed using the scontrol show nodes command, sinfo appears to report an incorrect value under certain conditions. For example, the TmpDisk parameter for my compute nodes is configured as 21800000 (21.8 TB) in slurm.conf, and this value is shown correctly with > scontrol show nodes ai-n007 ...... State=MIXED ThreadsPerCore=1 TmpDisk=21800000 Weight=1 Owner=N/A MCS_label=N/A .... However, when using the sinfo command with the -O Disk:20 option, the displayed value is 2180000, which is an order of magnitude lower: > sinfo -hO Disk:20 -n ai-n007 2180000 It appears that sinfo might be truncating or misinterpreting values with 8 or more digits. Has anyone encountered a similar issue? Is this a known bug in Slurm 24.05.3? Any suggestions or insights would be greatly appreciated. Best regards, Gizo

Unexpected node got allocation
by Dan Healy 09 Jan '25

09 Jan '25

Hello there and good morning from Baltimore. I have a small cluster with 100 nodes. When the cluster is completely empty of all jobs, the first job gets allocated to node 41. In other clusters, the first job gets allocated to mode 01. If I specify node 01, the allocation works perfectly. I have my partition NodeName set as node[01-99], so having node41 used first is a surprise to me. We also have many other partitions which start with node41, but the partition being used for the allocation starts with node01. Does anyone know what would cause this? Thanks, Daniel Healy

need help with seff script on ubuntu (slurm 21.08)

It doesn't change the most important values, but how is it possible not to have the same output?

All GPUs are Usable if no Gres is Defined
by Jacob Gordon 04 Jan '25

04 Jan '25

Hello, We have a two node GPU cluster with 8 NVidia GPUs. GRES is currently configured and works if a user defines it within their sbtach/interactive job submission (--gres=gpu:3). Users only have access to the GPUs they request. However, when they omit “--gres=gpu:n”, they can use every GPU, which interferes with running jobs that used the gres option. I’m at a loss as to why this is happening. Can someone please look at our configuration to see if anything stands out?

Resource guarantees
by christopher.furbee＠jhuapl.edu 23 Dec '24

23 Dec '24

Hello, Long time SGE admin, new SLURM admin here. I recently started the transition of all my clusters from SGE to SLURM and everything was great until I hit the "Taco Bell" cluster (fake name). Taco Bell supports 4 projects and under SGE we had a priority system setup using projects to balance the queue. For the life of me I have been unable to replicate this in SLURM. We are looking to configure guaranteed resources based on the project. I had thought we could accomplish this with QOS and accounts but so far we have failed. What we would like to end up with is; When project Gordita is running uncontested 100% of the cluster is available. While Gordita is running, if Crunchwrap submits their jobs we want the scheduler to prioritize those jobs until a 75% Gordita, 25% Crunchwrap balance of jobs is reached. No preempting or priority overriding, just as a Gordita job finishes, if Crunchwrap is less than 25%, start a Crunchwrap job. And then maintain that balance until one of the projects jobs are 100% completed. Any assistance or guidance is greatly appreciated.

sending mails wit smail on rocky9
by Marcus Wagner 19 Dec '24

19 Dec '24

Hi all, I have a problem with sending mails on rocky 9 via Slurm. One needs to install s-nail to have "/bin/mail" being available. There are some caveats in smail. In the second part (for the message, when the job began) one need to pipe ( eg echo "") into $MAIL, even in a script with no input, s-nail wants to be interactive. but it suffices to echo an empty text to snail. Nonetheless, I don't get any mail through. it seems the, mailprog for some reason gets killed or errors out for some other reason. While it is perfectionally working if run from the console :/ I all the time get in the slurmctld.log the following: 27212:[2024-12-19T15:54:54.935] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27213:[2024-12-19T15:54:54.945] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27214:[2024-12-19T15:54:54.945] error: MailProg returned error, it's output was '' 27395:[2024-12-19T15:55:55.540] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27396:[2024-12-19T15:55:55.551] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27397:[2024-12-19T15:55:55.551] error: MailProg returned error, it's output was '' 27438:[2024-12-19T15:56:55.981] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27439:[2024-12-19T15:56:55.981] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27440:[2024-12-19T15:56:55.992] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27441:[2024-12-19T15:56:55.992] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27442:[2024-12-19T15:56:55.992] error: MailProg returned error, it's output was '' 27443:[2024-12-19T15:56:55.992] error: MailProg returned error, it's output was '' 27450:[2024-12-19T15:56:58.849] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27451:[2024-12-19T15:56:58.859] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 0 any hints?

job_container/tmpfs, TmpFS and TmpDisk usage
by Paul Musset 16 Dec '24

16 Dec '24

Hello, I have multiple questions about the usage of job_container/tmpfs, and the TmpFS and TmpDisk variables 1) If my job_container.conf files contains: ``` BasePath=/mnt/slurm_tmp Shared=true ``` is it important what I set TmpFS to in slurm.conf ? Should I set it to '/mnt/slurm_tmp' or '/tmp' ? 2) What size should I put in TmpDisk ? the size advertised by df ? 3) Finally, is there any recommended file system for the partition used as the job_container/tmpfs BasePath ? Best regards, Paul Musset Max Planck Institute for Brain Research

Difference between sreport's cpu time usage and sacct -j usage

Node configuration unavailable when using --mem-per-gpu , for specific GPU type
by Matthew R. Baney 13 Dec '24

13 Dec '24

Hi all, I'm seeing some odd behavior when using the --mem-per-gpu flag instead of the --mem flag to request memory when also requesting all available CPUs on a node (in this example, all available nodes have 32 CPUs): $ srun --ntasks-per-node=8 --cpus-per-task=4 --gpus-per-node=gtx1080ti:1 --mem-per-gpu=1g --pty bash srun: error: Unable to allocate resources: Requested node configuration is not available $ srun --ntasks-per-node=8 --cpus-per-task=4 --gpus-per-node=gtx1080ti:1 --mem=1g --pty bash srun: job 3479971 queued and waiting for resources srun: job 3479971 has been allocated resources $ The nodes in this partition have a mix of gtx1080ti and rtx2080ti GPUs, but only one type of GPU is in any one node. The same behavior does not occur when requesting a (node with a) rtx2080ti instead. Is there something I'm missing that would cause the --mem-per-gpu flag to not be working in this example? Thanks, Matthew

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.

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.
