Slurm Reporting Difference between sreport and sacct
by Passant Hafez 23 May '25

23 May '25

Hi all, I was wondering if someone can help explaining this discrepancy. I have different values for project gpu consumption using sreport vs sacct (+ some calculations) This is an example that shows this: sreport -t hours -T gres/gpu cluster AccountUtilizationByuser start=2025-04-01 end=2025-04-05 | grep project1234 gives 178 while sacct -n -X --allusers --accounts=project1234 --start=2025-04-01 --end=2025-04-05 -o elapsedraw,AllocTRES%80,user,partition gives 213480 … [View More]

Crash in "slurmd -C" when latest NVIDIA drivers are used
by Taras Shapovalov 22 May '25

22 May '25

Hello, Does someone have idea why "slurmd -C" crashes when it unloads gpu_nrt.so with latest NVIDIA drivers (570 and 575)? We checked, there is no crash in cuda at the moment and gpu_nvml.so works fine, all nvml calls finish successfully, dlclose on gpu_nvml.so works fine. The crash does not depend whether real GPUs present or not. Steps to reproduce: 1. Install Ubuntu 24.04 2. wget https://download.schedmd.com/slurm/slurm-24.11.4.tar.bz2<https://download.schedmd.com/slurm/slurm-24.… [View More]

Wrong MaxRSS Behavior with cgroup v2 in Slurm
by Guillaume COCHARD 22 May '25

22 May '25

Hello, We've noticed a recent change in how MaxRSS is reported on our cluster. Specifically, the MaxRSS value for many jobs now often matches the allocated memory, which was not the case previously. It appears this change is due to how Slurm accounts for memory when copying large files, likely as a result of moving from cgroup v1 to cgroup v2. Here’s a simple example: copy_file.sh #!/bin/bash cp /distributed/filesystem/file5G /tmp cp /tmp/file5G ~ Two jobs with different memory allocations: … [View More]

Restrict and prioritize usage of certain nodes according to accounts
by thomas.hartmann＠th-ht.de 22 May '25

22 May '25

Hi, I'm going to have the following situation on my hands and I would like to ask for some suggestions how to solve this in slurm. We're talking about a cluster that is not yet operational so there are no real legacy configs that one needs to take into account. I have two sets of physical nodes: 1. node01 - nodeXX: General Purpose Nodes. Everybody can use them 2. project_A_01 - project_A_XX: These nodes come with some restrictions regarding who can and who must not run jobs on them. Users are … [View More]

Hi, I am trying to install the new version of slurm. Do you know if there is a way to find out what support is compiled into the executables? For example, apache has httpd -L which shows all the loaded modules. See below result: [image: image.png] *Fritz Ratnasamy*Data Scientist Information Technology

Performance Issues after Update to 24.11.5
by Tilman Hoffbauer 13 May '25

13 May '25

Hello, we are running a SLURM-managed cluster with one control node (g-vm03) and 26 worker nodes (ouga[03-28]) on Rocky 8. We recently updated from 20.11.9 through 23.02.8 to 24.11.0 and then 24.11.5. Since then, we are experiencing performance issues - squeue and scontrol ping are slow to react and sometimes deliver "timeout on send/recv" messages, even with only very few parallel requests. We did not experience these issues with SLURM 20.11.9 before, we did not check the intermediate … [View More]
