Job Step State
by Emyr James 01 Oct '24

01 Oct '24

Dear all, I am working on a script to take completed job accounting data from the slurm accounting database and insert the equivalent data into a clickhouse table for fast reporting I can see that all the information is included in the cluster_job_table and cluster_job_step_table which seem to be joined on job_db_inx To get the cpu usage and peak memory usage etc. I can see that I need to parse the tres columns in the job steps. I couldn't find any column called MaxRSS in the database even though the sacct command prints this. I then found some data in tres_table and assume that sacct is using this. Please correct me if I'm wrong and if sacct is getting information from somwhere other than the accounting database? for the state column I get this... select state, count(*) as num from crg_step_table group by state order by num desc limit 10; +-------+--------+ | state | num | +-------+--------+ | 3 | 590635 | | 5 | 28345 | | 4 | 4401 | | 11 | 962 | | 1 | 8 | +-------+--------+ When I use sacct I see statuses seach as COMPLETED, OUT_OF_MEMORY etc. so there must be a mapping somewhere between these state ids and that text. Can someone prvide that mapping or point me to where it's defined in the database or in the code ? Many thanks, Emyr James Head of Scientific IT CRG - Centre for Genomic Regulation

Hardcoded CGroups v2 Slice
by Khalid Al-Hawaj 01 Oct '24

01 Oct '24

Hello, I am in the process of setting up SLURM to be used in a profiling cluster. The purpose of SLURM is to allow users to submit jobs to be profiled. The latency is a very important aspect of profiling the applications correctly. I was able to leverage cgroupsv2.0 to isolate user.slice from the cores that would be used by SLURM jobs. The issue is that slurmstepd shares the resources with system.slice; I was digging through the code, and I saw that the creation of the scope is here: https://github.com/SchedMD/slurm/blob/master/src/plugins/cgroup/v2/cgroup_v… And I noticed that the slice is hardcoded in the following line: https://github.com/SchedMD/slurm/blob/master/src/plugins/cgroup/v2/cgroup_v… So, my question, now, is about why is the slice hardcoded? What was the reason behind such a decision? I would have thought that the slice chosen would be set through cgroups.conf, instead. I would like to switch the slice for slurmstepd to a slice other than system.slice; by doing so, I would be able to isolate cores better by making sure that services' processes are isolated from the cores used for SLURM jobs. I can definitely change the defined value in the code and recompile. Are there anything to consider before doing so? Thanks, Khalid

Updated one compute node to Ubuntu 24.04 LTS, now it does not receive jobs
by Cristóbal Navarro 29 Sep '24

29 Sep '24

Dear community, I am having a strange issue I have been unable to find the cause. Last week I did a full update on the cluster, which is composed of the master node, and two compute nodes (nodeGPU01 -> DGXA100 and nodeGPU02 -> custom GPU server). After the update, I got - master node ended up with Ubuntu 24.04, - nodeGPU01 with latest DGX OS (still Ubuntu 22.04) - nodeGPU02 with Ubuntu 24.04 LTS. - Launching jobs from master choosing the partitions of nodeGPU01 works perfectly. - Launching jobs from master choosing the partition of nodeGPU02 stopped working (hangs). The nodeGPU02 (Ubuntu 24) is no longer processing jobs successfully, while the other nodeGPU01 works perfectly even when the master has Ubuntu 24. Any help is welcome, I have tried many things and had no success in finding the cause of this. Please let me know if you need more information. Many thanks in advance. This is the initial `slurmd` log of the problematic node (nodeGPU02), notice the messages in yellow ➜ ~ sudo systemctl status slurmd.service ● slurmd.service - Slurm node daemon Loaded: loaded

errors compiling Slurm 18 on RHEL 9: [Makefile:577: scancel] Error 1 & It's not recommended to have unversioned Obsoletes

We're in the process of upgrading but first we're moving to RHEL 9.

A note on updating Slurm from 23.02 to 24.05 & multi-cluster
by Ward Poelmans 26 Sep '24

26 Sep '24

Hi all, We hit a snag when updating our clusters from Slurm 23.02 to 24.05. After updating the slurmdbd, our multi cluster setup was broken until everything was updated to 24.05. We had not anticipated this. SchedMD says that fixing it would be a very complex operation. Hence, this warning to everybody on planning to update: make sure to quickly updating everything once you've updated the slurmdbd daemon.

Jobs pending with reason "priority" but nodes are idle
by Long, Daniel S. 25 Sep '24

25 Sep '24

Hi, On our cluster we have some jobs that are queued even though there are available nodes to run on. The listed reason is "priority" but that doesn't really make sense to me. Slurm isn't picking another job to run on those nodes; it's just not running anything at all. We do have a quite heterogeneous cluster, but as far as I can tell the queued jobs aren't requesting anything that would preclude them from running on the idle nodes. They are array jobs, if that makes a difference. Thanks for any help you all can provide.

Max TRES per user and node
by Guillaume COCHARD 25 Sep '24

25 Sep '24

Hello, We are looking for a method to limit the TRES used by each user on a per-node basis. For example, we would like to limit the total memory allocation of jobs from a user to 200G per node. There is MaxTRESperNode (https://slurm.schedmd.com/sacctmgr.html#OPT_MaxTRESPerNode), but unfortunately, this is a per-job limit, not per user. Ideally, we would like to apply this limit on partitions and/or QoS. Does anyone know if this is possible and how to achieve it? Thank you,

SLURM Telegraf Plugin
by Pablo Collado Soto 25 Sep '24

25 Sep '24

Hi all, I recently wrote an SLURM input plugin [0] for Telegraf [1]. I just wanted to let the community know so that you can use it if you'd find that useful. Maybe its existence can also be included in the documentation somewhere? Anyway, thanks a ton for your time, Pablo Collado Soto References: 0: https://github.com/influxdata/telegraf/tree/master/plugins/inputs/slurm 1: https://www.influxdata.com/time-series-platform/telegraf/ + -------------------------------------- + | Never let your sense of morals prevent | | you from doing what is right. | | -- Salvor Hardin, "Foundation" | + -------------------------------------- +
