slurmdbd archive format
by O'Neal, Doug (NIH/NCI) [C] 28 May '24

28 May '24

My organization needs to access historic job information records for metric reporting and resource forecasting. slurmdbd is archiving only the job information, which should be sufficient for our numbers, but is using the default archive script. In retrospect, this data should have been migrated to a secondary MariaDB instance, but that train has passed. The format of the archive files is not well documented. Does anyone have a program (python/C/whatever) that will read a job_table_archive file … [View More]

Performance Discrepancy between Slurm and Direct mpirun for VASP Jobs.
by Hongyi Zhao 27 May '24

Dear Slurm Users, I am experiencing a significant performance discrepancy when running the same VASP job through the Slurm scheduler compared to running it directly with mpirun.

Building Slurm debian package vs building from source
by Arnuld 23 May '24

23 May '24

We have several nodes, most of which have different Linux distributions (distro for short). Controller has a different distro as well. The only common thing between controller and all the does is that all of them ar x86_64. I can install Slurm using package manager on all the machines but this will not work because controller will have a different version of Slurm compared to the nodes (21.08 vs 23.11) If I build from source then I see two solutions: - build a deb package - build a custom … [View More]

memory high water mark reporting
by Emyr James 22 May '24

22 May '24

Hi, We are trying out slurm having been running grid engine for a long while. In grid engine, the cgroups peak memory and max_rss are generated at the end of a job and recorded. It logs the information from the cgroup hierarchy as well as doing a getrusage call right at the end on the parent pid of the whole job "container" before cleaning up. With slurm it seems that the only way memory is recorded is by the acct gather polling. I am trying to add something in an epilog script to get the … [View More]

Slurm not allocating correct cgroup cpu ids in srun step (possible bug)
by Ashley Wright 21 May '24

21 May '24

Hi, At our site we have recently upgraded to Slurm 23.11.5 and are having trouble with MPI jobs doing srun inside a sbatch'ed script. The cgroup does not appear to be setup correctly for the srun (step_0). As an example $ cat /sys/fs/cgroup/cpuset/slurm/uid_11000..../job..../cpuset.cpus 0,2-3,68-69,96,98-99,164-165 $ cat /sys/fs/cgroup/cpuset/slurm/uid_11000..../job..../step_0/cpuset.cpus 0,2,68,96,98,164 The sbatch is allocated a range of cpus in the cgroup. However, when step_0 is run, … [View More]
