Hello, I'm doing some test with "associations" with "sacctmgr". I have created three users (user_1, user_2 and user_3).

Redirect jobs submitted to old partition to new
by wdennis＠nec-labs.com 16 Apr '24

16 Apr '24

Hi all, I have a single-partition Slurm cluster (the single partition name being "default_queue") that I now want to implement multiple different queues on to subdivide the resources. Say the new default queue is "queue1"; Should I set the "default_queue" to `State=INACTIVE` and then use `Alternate=queue1` on it to redirect jobs sent to the old "default_queue" to end up on "queue1"? Thinking it would be nice to have an AltPartitionName= construct to handle this... (must be a reason this doesn't exist)

Slurm version 23.11.6 is now available
by Marshall Garey 16 Apr '24

16 Apr '24

We are pleased to announce the availability of Slurm version 23.11.6. The 23.11.6 release includes two different problems with the priority/multifactor plugin: a crash and a miscalculation of AssocGrpCPURunMinutes after a slurmctld reconfiguration/restart. The wsrep_on errors that sites running MySQL or older MariaDB should happen much less frequently and has a clarifying statement when it is an innocuous error.

Fwd: sreport cluster UserUtilizationByaccount Used result versus sreport job SizesByAccount or sacct: inconsistencies
by KK 15 Apr '24

---------- Forwarded message --------- 发件人： KK <daijiangkuicgo(a)gmail.com> Date: 2024年4月15日周一 13:25 Subject: sreport cluster UserUtilizationByaccount Used result versus sreport job SizesByAccount or sacct: inconsistencies To: <slurm-users(a)schedmd.com> I wish to ascertain the CPU core hours utilized by user dj1 and dj. I have tested with sreport cluster UserUtilizationByAccount, sreport job SizesByAccount, and sacct. It appears that sreport cluster UserUtilizationByAccount … [View More]displays the total core hours used by the entire account, rather than the individual user's cpu time. Here are the specifics: Users dj and dj1 are both under the account mehpc. In 2024-04-12 ~ 2024-04-15, dj1 used approximately 10 minutes of core time, while dj used about 4 minutes. However, "*sreport Cluster UserUtilizationByAccount user=dj1 start=2024-04-12 end=2024-04-15*" shows 14 minutes of usage. Similarly, "*sreport job SizesByAccount Users=dj start=2024-04-12 end=2024-04-15*" hows about 14 minutes. Using "*sreport job SizesByAccount Users=dj1 start=2024-04-12 end=2024-04-15*" or "*sacct -u dj1 -S 2024-04-12 -E 2024-04-15 -o "jobid,partition,account,user,alloccpus,cputimeraw,state,workdir%60" -X |awk 'BEGIN{total=0}{total+=$6}END{print total}'*" yields the accurate values, which are around 10 minutes for dj1.

Slurm.conf and workers
by Xaver Stiensmeier 15 Apr '24

15 Apr '24

Dear slurm-user list, as far as I understood it, the slurm.conf needs to be present on the master and on the workers at slurm.conf (if no other path is set via SLURM_CONF). However, I noticed that when adding a partition only in the master's slurm.conf, all workers were able to "correctly" show the added partition when calling sinfo on them. Is the stored slurm.conf on every instance just a fallback for when connection is down or what is the purpose? The documentation only says: "This file … [View More]

Interfaces of topology/tree and Topology Awareness
by nico.derl＠tutanota.com 15 Apr '24

15 Apr '24

Hello everyone, I'm trying to improve topology awareness in a local Slurm-managed HPC system. It's using the default hierarchical 3-level topology with the tree-plugin. It however does not always confine jobs to the most tightly packed group of nodes, seems to over-provision switches for smaller jobs, and gets slow or overwhelmed with jobs that have a high node count. I'd like to implement something more literally aligned with best-fit, but I'm having trouble understanding the relevant … [View More]

Is here anybody having nice visualization of JobComp and JobacctGather data in Grafana? I save JobComp data in Elasticsearch, JobacctGather data in influxDB, and thinking about how to provide meaningful insights to $users. Things I'd like to show..: especially memory & cpu utilization, job result, possible malicious effects like OOMs... Any screenshots, ideas, experience welcomed! cheers Josef
