Tracking GPU utilization with sacct
by Robertson, Jordan 03 Jun '24

03 Jun '24

Hi all, I’m trying to pull (and understand) some GPU usage metrics for historical purposes, and dug into sacct’s TRES reporting a bit. We have AccountingStorageTRES=gres/gpu set in slurm.conf so we do see gres/gpuutil and gres/gpumem numbers available, but I’m struggling to find Slurm-side documentation that describes the units of these values. In looking at the code for gpu_nvml.c it seems the “nvmlDeviceGetProcessUtilization” function is being used and returns units in percentages, but I’m … [View More]

sbatch and --nodes
by Michael DiDomenico 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 … [View More]

Re: Container Jobs "hanging"
by Joshua Randall 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 … [View More]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 ? But most importantly I wanted to know why it takes so long through systemctl. Maybe I can increase the timeout limit ?

Executing srun -n X where X is greater than total CPU in entire cluster
by Dan Healy 30 May '24

30 May '24

Hi there, SLURM community, I swear I've done this before, but now it's failing on a new cluster I'm deploying. We have 6 compute nodes with 64 cpu each (384 CPU total). When I run `srun -n 500 hostname`, the task gets queued since there's not 500 available CPU. Wasn't there an option that allows for this to be run where the first 384 tasks execute, and then the remaining execute when resources free up? Here's my conf: # Slurm Cgroup Configs used on controllers and workersslurm_cgroup_config:… [View More]

Jobs showing running but not running

Hi All, I'm managing a cluster with Slurm, consisting of 4 nodes. One of the compute nodes appears to be experiencing issues. While the front node's 'squeue' command indicates that jobs are running, upon connecting to the problematic node, I observe no active processes and GPUs are not being utilized.

dynamical configuration || meta configuration mgmt
by Heckes, Frank 29 May '24

29 May '24

Hello all, I’m sorry if this has been asked and answered before, but I couldn’t find anything related. Does anyone know whether a framework of sorts exists that allow to change certain SLURM configuration parameters provided some conditions in the batch system’s state are detected and of course are revert if the state became the old one again? (To be more concrete: We like to raise or unset maxjobPU to run as much small jobs as possible to allocate all nodes as soon as certain threshold … [View More]

Configuring sacct to report state=OUT_OF_MEMORY
by Lee 29 May '24

29 May '24

Hello, *Background :* I am working on a small cluster that is managed by Base Command Manager v10.0 using Slurm 23.02.7 with Ubuntu 22.04.2. I have a small testing script that simply consumes memory and processors. I run my test script, it consumes more memory than allocated by Slurm and as expected it gets killed by OOM killer. In /var/log/slurmd, I see entries like : [2024-05-29T08:53:04.975] Launching batch job 65 for UID 1001 [2024-05-29T08:53:05.016] [65.batch] task/cgroup: … [View More]_memcg_initialize: job: alloc=10868MB mem.limit=10868MB memsw.limit=10868MB job_swappiness=1 [2024-05-29T08:53:05.016] [65.batch] task/cgroup: _memcg_initialize: step: alloc=10868MB mem.limit=10868MB memsw.limit=10868MB job_swappiness=1 [2024-05-29T08:53:19.530] [65.batch] task/cgroup: task_cgroup_memory_check_oom: StepId=65.batch hit memory+swap limit at least once during execution.

How do I configure [slurm,cgroup].conf such that when Slurm kills a job due to exceeding the allocated memory, sacct reports the state as OUT_OF_MEMORY?
