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

AllowAccounts partition setting
by Marko Markoc 17 Oct '24

17 Oct '24

Hi All, At one point, when we were running slurm 22, we set up a few new partitions with `AllowAccounts` setting enabled. We limit access to these partitions only to a few accounts. We manually create these accounts and users using the `sacctmgr` command. At that time, everything was working. Only users in these accounts were able to run jobs in that partition. Few months ago we upgraded slurm to 23.02.7 but just a couple of days ago we noticed that anyone could submit jobs to these partitions. In addition to that, you can provide any value to the `--account` directive and slurm will accept and record it in the job accounting database. In our initial testing, you could only provide `--account` value that has been previously created. I'm still looking into this but I wanted to check if there was any change in version 23 that could have impacted this? I don't remember seeing anything in release notes. Thanks, Marko

Can't schedule on cloud node: State=IDLE+CLOUD+POWERED_DOWN+NOT_RESPONDING
by Xaver Stiensmeier 20 Sep '24

20 Sep '24

Dear slurm-user list, I have a cloud node that is powered up and down on demand. Rarely it can happen that slurm's resumeTimeout is reached and the node is therefore powered down. We have set ReturnToService=2 in order to avoid the node being marked down, because the instance behind that node is created on demand and therefore after a failure nothing stops the system to start the node again as it is a different instance. I thought this would be enough, but apparently the node is still marked with "NOT_RESPONDING" which leads to slurm not trying to schedule on it. After a while NOT_RESPONDING is removed, but I would like to move it directly from within my fail script if possible so that the node can return to service immediately and not be blocked by "NOT_RESPONDING". Best regards, Xaver

_refresh_assoc_mgr_qos_list: no new list given back keeping cached one
by joao.damas＠syngenta.com 05 Aug '24

05 Aug '24

Hi all, We are doing a simple setup for a Slurm cluster (version 23.11.6). We follow the documentation and we are trying a setup still without accounting or slurmdbd. The slurm.conf is really simple: ``` ClusterName=Develop SlurmctldHost=head # Slurm configuration AuthType=auth/munge CryptoType=crypto/munge SlurmctldLogFile=/var/log/slurm/slurmctld.log SlurmctldPidFile=/var/run/slurmctld.pid SlurmctldPort=6817 SlurmdLogFile=/var/log/slurm/slurmd.log SlurmdPidFile=/var/run/slurmd.pid SlurmdPort=6818 SlurmdSpoolDir=/var/spool/slurmd SlurmUser=slurm StateSaveLocation=/var/spool/slurmctld # Nodes NodeName=worker1 CoresPerSocket=2 Sockets=1 ThreadsPerCore=1 NodeName=worker2 CoresPerSocket=2 Sockets=1 ThreadsPerCore=1 # Partitions PartitionName=develop Default=YES MaxTime=UNLIMITED Nodes="worker1,worker2" ``` When running a simple `srun sleep 10`, all works well and the log file shows: [2024-05-15T12:34:12.741] sched: _slurm_rpc_allocate_resources JobId=1 NodeList=worker1 usec=549 [2024-05-15T12:34:22.775] _job_complete: JobId=1 WEXITSTATUS 0 [2024-05-15T12:34:22.775] _job_complete: JobId=1 done But when creating a scrip with the same sleep command, and submiting using `sbatch test.sh`, the log shows: [2024-05-15T12:35:39.916] _slurm_rpc_submit_batch_job: JobId=2 InitPrio=1 usec=368 [2024-05-15T12:35:40.000] error: _refresh_assoc_mgr_qos_list: no new list given back keeping cached one.

Looking at the function that seems to spit out that error (https://github.com/SchedMD/slurm/blob/e9f28ede27795f525e62f998cb2d40931d884…), it appears like there should be some accounting setup? We do not have slurmdbd setup and the documentation states we should test basic functionality before implementing that daemon. Any tips? Thanks in advance. João

Convergence of Kube and Slurm?
by Dan Healy 29 Jul '24

29 Jul '24

Bright Cluster Manager has some verbiage on their marketing site that they can manage a cluster running both Kubernetes and Slurm. Maybe I misunderstood it. But nevertheless, I am encountering groups more frequently that want to run a stack of containers that need private container networking. What’s the current state of using the same HPC cluster for both Slurm and Kube? Note: I’m aware that I can run Kube on a single node, but we need more resources. So ultimately we need a way to have Slurm and Kube exist in the same cluster, both sharing the full amount of resources and both being fully aware of resource usage. Thanks, Daniel Healy

Problems with gres.conf
by Gestió Servidors 04 Jun '24

Hello, I am trying to rewrite my gres.conf file. Before changes, this file was just like this: NodeName=node-gpu-1 AutoDetect=off Name=gpu Type=GeForceRTX2070 File=/dev/nvidia0 Cores=0-11 NodeName=node-gpu-1 AutoDetect=off Name=gpu Type=GeForceGTX1080Ti File=/dev/nvidia1 Cores=12-23 NodeName=node-gpu-2 AutoDetect=off Name=gpu Type=GeForceGTX1080Ti File=/dev/nvidia0 Cores=0-11 NodeName=node-gpu-2 AutoDetect=off Name=gpu Type=GeForceGTX1080 File=/dev/nvidia1 Cores=12-23 NodeName=node-gpu-3 AutoDetect=off Name=gpu Type=GeForceRTX3080 File=/dev/nvidia0 Cores=0-11 NodeName=node-gpu-4 AutoDetect=off Name=gpu Type=GeForceRTX3080 File=/dev/nvidia0 Cores=0-7 # you can seee that nodes node-gpu-1 and node-gpu-2 have two GPUs each one, whereas nodes node-gpu-3 and node-gpu-4 have only one GPU each one And my slurmd.conf was this: [...] AccountingStorageTRES=gres/gpu GresTypes=gpu NodeName=node-gpu-1 CPUs=24 SocketsPerBoard=2 CoresPerSocket=6 ThreadsPerCore=2 RealMemory=96000 TmpDisk=47000 Gres=gpu:GeForceRTX2070:1,gpu:GeForceGTX1080Ti:1 NodeName=node-gpu-2 CPUs=24 SocketsPerBoard=2 CoresPerSocket=6 ThreadsPerCore=2 RealMemory=96000 TmpDisk=47000 Gres=gpu:GeForceGTX1080Ti:1,gpu:GeForceGTX1080:1 NodeName=node-gpu-3 CPUs=12 SocketsPerBoard=1 CoresPerSocket=6 ThreadsPerCore=2 RealMemory=23000 Gres=gpu:GeForceRTX3080:1 NodeName=node-gpu-4 CPUs=8 SocketsPerBoard=1 CoresPerSocket=4 ThreadsPerCore=2 RealMemory=7800 Gres=gpu:GeForceRTX3080:1 NodeName=node-worker-[0-22] CPUs=12 SocketsPerBoard=1 CoresPerSocket=6 ThreadsPerCore=2 RealMemory=47000 [...] With this configuration, all seems works fine, except slurmctld.log reports: [...] error: _node_config_validate: gres/gpu: invalid GRES core specification (0-11) on node node-gpu-3 error: _node_config_validate: gres/gpu: invalid GRES core specification (12-23) on node node-gpu-1 error: _node_config_validate: gres/gpu: invalid GRES core specification (12-23) on node node-gpu-2 error: _node_config_validate: gres/gpu: invalid GRES core specification (0-7) on node node-gpu-4 [...] However, even these errors, users can submit jobs and request GPUs resources.

sbatch and --nodes
by Michael DiDomenico 31 May '24

31 May '24

its friday and i'm either doing something silly or have a misconfig somewhere, i can't figure out which when i run sbatch --nodes=1 --cpus-per-task=1 --array=1-100 --output test_%A_%a.txt --wrap 'uname -n' sbatch doesn't seem to be adhering to the --nodes param. when i look at my output files it's spreading them across more nodes. in the simple case above it's 50/50, but if i through a random sleep in, it'll be more. and if i expand the array it'll use even more nodes. i'm using con/tres and have cr_core_memory,cr_one_core_per_task set

Re: Container Jobs "hanging"
by Joshua Randall 31 May '24

31 May '24

Hi Sean, I appear to be having the same issue that you are having with OCI container jobs running forever / appearing to hang. I haven't figured it out yet, but perhaps we can compare notes and determine what aspect of configuration we both share. Like you, I was following the examples in https://slurm.schedmd.com/containers.html and originally encountered the issue with an alpine container image running the `uptime` command, but I have also confirmed the issue with other images including ubuntu and with other processes. I always get the same results - the container process runs to completion and exits, but then the slurm job continues to run until it is cancelled or killed. I have slurm v23.11.6 and am using the nvidia-container-runtime, what slurm version and runtime are you using? My oci.conf is: ``` $ cat /etc/slurm/oci.conf EnvExclude="^(SLURM_CONF|SLURM_CONF_SERVER)=" RunTimeEnvExclude="^(SLURM_CONF|SLURM_CONF_SERVER)=" RunTimeQuery="nvidia-container-runtime --rootless=true --root=/run/user/%U/ state %n.%u.%j.%s.%t" RunTimeKill="nvidia-container-runtime --rootless=true --root=/run/user/%U/ kill -a %n.%u.%j.%s.%t" RunTimeDelete="nvidia-container-runtime --rootless=true --root=/run/user/%U/ delete --force %n.%u.%j.%s.%t" RunTimeRun="nvidia-container-runtime --rootless=true --root=/run/user/%U/ run %n.%u.%j.%s.%t -b %b" ``` Hope that we can get to the bottom of this and resolve our issues with OCI containers! Josh. --- Hello. I am new to this list and Slurm overall. I have a lot of experience in computer operations, including Kubernetes, but I am currently exploring Slurm in some depth. I have set up a small cluster and, in general, have gotten things working, but when I try to run a container job, it runs the command but then appears to hang as if the job container is still running. So, running the following works, but it never returns to the prompt unless I use [Control-C]. $ srun --container /shared_fs/shared/oci_images/alpine uptime 19:21:47 up 20:43, 0 users, load average: 0.03, 0.25, 0.15 I'm unsure if something is misconfigured or if I'm misunderstanding how this should work, but any help and/or pointers would be greatly appreciated.

manually running it through sudo slurmdbd -D /path/to/conf is very quick on my fresh install trying to start the slurmdbd through systemctl take 3 minutes and then crashes and fail Is there an alternative to systemctl to start the slurmdbd in the background ?
