slurmctld hourly: Unexpected missing socket error
by Jason Ellul 13 Jan '26

13 Jan '26

Hi all, I am hoping someone can help with our problem. Every hour after restarting slurmctld the controller becomes unresponsive to commands for 1 sec, reporting errors such as: [2024-07-15T11:45:48.509] error: slurm_send_node_msg: [socket:[934767]] slurm_bufs_sendto(msg_type=RESPONSE_JOB_INFO) failed: Unexpected missing socket error [2024-07-15T11:45:48.509] error: slurm_send_node_msg: [socket:[934760]] slurm_bufs_sendto(msg_type=RESPONSE_SLURM_RC) failed: Unexpected missing socket error [2024-07-15T11:45:48.509] error: slurm_send_node_msg: [socket:[934875]] slurm_bufs_sendto(msg_type=RESPONSE_JOB_INFO) failed: Unexpected missing socket error [2024-07-15T11:45:48.509] error: slurm_send_node_msg: [socket:[934906]] slurm_bufs_sendto(msg_type=RESPONSE_JOB_INFO) failed: Unexpected missing socket error [2024-07-15T11:45:48.509] error: slurm_send_node_msg: [socket:[939016]] slurm_bufs_sendto(msg_type=RESPONSE_JOB_INFO) failed: Unexpected missing socket error It occurs consistently at around the hour mark, but generally not at other times, unless we run a reconfigure or restart the controller. We don’t see any issues in the slurmdbd.log and the errors are also always msg type RESPONSE. We have tried building a new server on different infrastructure, but the problem has persisted. Yesterday we even tried updating slurm to v24.05.1 in the hope that may provide a fix. During our troubleshooting we have: Set: * SchedulerParameters = max_rpc_cnt=400,sched_min_interval=50000,sched_max_job_start=300,batch_sched_delay=20,bf_resolution=600,bf_min_prio_reserve=2000,bf_min_age_reserve=600 * SlurmctldPort = 6808-6817 But although the stats in sdiag have improved we still see the errors. On our monitoring software we also see a drop in network and disk activity during this 1 second, always at approx. 1 hour after restarting the controller.

job_container/tmpfs and srun.
by Phill Harvey-Smith 17 Jan '25

17 Jan '25

Hi all, On our setup we are using job_container/tmpfs to give each job it's own temp space. Since our compute nodes have reasonably sized disks for tasks that do a lot of disk I/O on user's data we have asked users to copy their data to the local disk at the beginning of the task and (if needed) copy it back at the end. This saves lots of NFS thrashing slowing down both the task and the NFS servers. However some of our users are having problems with this, their initial sbatch script will create a temp directory in their private /tmp copy their data to it and then try to srun a program. The srun will fall over as it doesn't seem to have have access to the copied data. I suspect this is because the srun task is getting it's own private /tmp. So my question is, is there a way to have the srun task inherit the /tmp of the initial sbatch? I'll include a sample of the script our user is using below. If any further information is required please feel free to ask. Cheers. Phill. #!/usr/bin/bash #SBATCH --nodes 1 #SBATCH --ntasks-per-node=1 #SBATCH --cpus-per-task=1 #SBATCH --time=00:00:10 #SBATCH --mem-per-cpu=3999 #SBATCH --output=script_out.log #SBATCH --error=script_error.log # The above options puts the STDOUT and STDERR of sbatch in # log files prefixed with 'script_'. # Create a randomly-named directory under /tmp jobtmpdir=$(mktemp -d) # Register a function to try and cleanup in case of job failure cleanup_handler() { echo "Cleaning up ${jobtmpdir}" rm -rf ${jobtmpdir} } trap 'cleanup_handler' SIGTERM EXIT # Change working directory to this directory cd ${jobtmpdir} # Copy the executable and input files from # where the job was submitted to the temporary directory. cp ${SLURM_SUBMIT_DIR}/a.out . cp ${SLURM_SUBMIT_DIR}/input.txt . # Run the executable, handling the collection of stdout # and stderr ourselves by redirecting to file srun ./a.out 2> task_error.log > task_out.log # Copy output data back to the submit directory. cp output.txt ${SLURM_SUBMIT_DIR} cp task_out.log ${SLURM_SUBMIT_DIR} cp task_error.log ${SLURM_SUBMIT_DIR} # Cleanup cd ${SLURM_SUBMIT_DIR} cleanup_handler

Why AllowAccounts not work in slurm-23.11.6
by daijiangkuicgo＠gmail.com 30 Oct '24

AllowAccounts partition setting
by Marko Markoc 17 Oct '24

17 Oct '24

Hi All, At one point, when we were running slurm 22, we set up a few new partitions with `AllowAccounts` setting enabled. We limit access to these partitions only to a few accounts. We manually create these accounts and users using the `sacctmgr` command. At that time, everything was working. Only users in these accounts were able to run jobs in that partition. Few months ago we upgraded slurm to 23.02.7 but just a couple of days ago we noticed that anyone could submit jobs to these partitions. In addition to that, you can provide any value to the `--account` directive and slurm will accept and record it in the job accounting database. In our initial testing, you could only provide `--account` value that has been previously created. I'm still looking into this but I wanted to check if there was any change in version 23 that could have impacted this? I don't remember seeing anything in release notes. Thanks, Marko

SLURM GRES reservation not working properly on 24.05.1
by Minulakshmi S 07 Oct '24

07 Oct '24

Hello, *Issue 1:* I am using slurm version 24.05.1 , my slurmd has a single node where I connect multiple gres by enabling the overscribe feature. I am able to use the advance reservation of gres only using *gres** name* (tres=gres/gpu:*SYSTEM12*). i.e while in reservation period , if other users submits job with SYSTEM12 , then slurm places this job in queue *user1@host$ srun --gres=gpu:SYSTEM12:1 hostname* *srun: job 333 queued and waiting for resources * but when other users just submit a job without any system name , slurm jobs goes through on that gres immediately even though it is reserved. *user1@host$ srun --gres=gpu:1 hostname * *mylinux.wbi.com <http://mylinux.wbi.com/> * Also I can see GresUsed in busy mode using "*scontrol show node -d*" , this means the job is running on Gres/GPU and not on cpu etc. Same way , job submission based on Feature "rev1 in my case" is also going through even though it is reserved for other users in multiple partition slurm. *snippet of slurm.conf file* NodeName=cluster01 NodeAddr=cluster Port=6002CPUs=8 Boards=1 SocketsPerBoard=1 CoresPerSocket=8 ThreadsPerCore=2 Feature="rev1" Gres=gpu:SYSTEM12:1 RealMemory=64171 State=IDLE *Issue 2:* while execution , Slurm o/p's some extra prints in the srun output user1@host$ srun --gres=gpu:1 hostname srun: error: extract_net_cred: net_cred not provided srun: error: Malformed RPC of type RESPONSE_NODE_ALIAS_ADDRS(3017) received srun: error: slurm_unpack_received_msg: [mylinux.wbi.com]:41242] Header lengths are longer than data received *mylinux.wbi.com <http://mylinux.wbi.com/>* Regards, MS

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

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. My attempt to compile using rpmbuild -v -ta --define "_lto_cflags %{nil}" slurm-18.08.9.tar.bz2 (H/T to Brian for this flag <https://groups.google.com/g/slurm-users/c/W8YfGIn1rDI/m/4bsSAoqZAAAJ>). I've stumped Google and the Slurm mailing list with the scancel error so hoping someone here knows of a work around. /bin/ld: opt.o:/root/rpmbuild/BUILD/slurm-18.08.9/src/scancel/../../src/scancel/scancel.h:78: multiple definition of `opt';

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,

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?

Setting up fairshare accounting
by tluchko 24 Sep '24

24 Sep '24

Hello, We have a new cluster and I'm trying to setup fairshare accounting. I'm trying to track CPU, MEM and GPU. It seems that billing for individual jobs is correct, but billing isn't being accumulated (TRESRunMin is always 0). In my slurm.conf, I think the relevant lines are AccountingStorageType=accounting_storage/slurmdbd AccountingStorageTRES=gres/gpu PriorityFlags=MAX_TRES PartitionName=gpu Nodes=node[1-7] MaxCPUsPerNode=384 MaxTime=7-0:00:00 State=UP TRESBillingWeights="CPU=1.0,MEM=0.125G,GRES/gpu=9.6" PartitionName=cpu Nodes=node[1-7] MaxCPUsPerNode=182 MaxTime=7-0:00:00 State=UP TRESBillingWeights="CPU=1.0,MEM=0.125G,GRES/gpu=9.6" I currently have one recently finished job and one running job. sacct gives $ sacct --format=JobID,JobName,ReqTRES%50,AllocTRES%50,TRESUsageInAve%50,TRESUsageInMax%50 JobID JobName ReqTRES AllocTRES TRESUsageInAve TRESUsageInMax ------------ ---------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- 154 interacti+ billing=9,cpu=1,gres/gpu=1,mem=1G,node=1 billing=9,cpu=2,gres/gpu=1,mem=2G,node=1 154.interac+ interacti+ cpu=2,gres/gpu=1,mem=2G,node=1 cpu=00:00:00,energy=0,fs/disk=2480503,mem=3M,page+ cpu=00:00:00,energy=0,fs/disk=2480503,mem=3M,page+ 155 interacti+ billing=9,cpu=1,gres/gpu=1,mem=1G,node=1 billing=9,cpu=2,gres/gpu=1,mem=2G,node=1155.interac+ interacti+ cpu=2,gres/gpu=1,mem=2G,node=1 billing=9 seems correct to me, since I have 1 GPU allocated, which has the largest score of 9.6.

what updates NODEADDR
by Jakub Szarlat 21 Sep '24

21 Sep '24

Hi I'm using dynamic nodes with "slurmd -Z" with slurm 23.11.1. Firstly I find that when you do "scontrol show node" it shows the NODEADDR as ip rather than the NODENAME. Because I'm playing around with running this in containers on docker swarm I find this ip can be wrong. I can force it with scontrol update however after a while something updates it to something else again. Does anybody know if this is done by slurmd or slurmctld or something else? How can I stop this from happening? How can I get the node to register with the hostname rather than ip? cheers, Jakub

SLURM GRES reservation not working properly on 24.05.1
by Minulakshmi S 20 Sep '24

20 Sep '24

Hello, *Issue 1:* I am using slurm version 24.05.1 , my slurmd has a single node where I connect multiple gres by enabling the overscribe feature. I am able to use the advance reservation of gres only using *gres** name* (tres=gres/gpu:*SYSTEM12*). i.e while in reservation period , if other users submits job with SYSTEM12 , then slurm places this job in queue *user1@host$ srun --gres=gpu:SYSTEM12:1 hostname* *srun: job 333 queued and waiting for resources * but when other users just submit a job without any system name , slurm jobs goes through on that gres immediately even though it is reserved. *user1@host$ srun --gres=gpu:1 hostname * *mylinux.wbi.com <http://mylinux.wbi.com> * Also I can see GresUsed in busy mode using "*scontrol show node -d*" , this means the job is running on Gres/GPU and not on cpu etc. Same way , job submission based on Feature "rev1 in my case" is also going through even though it is reserved for other users in multiple partition slurm. *snippet of slurm.conf file* NodeName=cluster01 NodeAddr=cluster Port=6002CPUs=8 Boards=1 SocketsPerBoard=1 CoresPerSocket=8 ThreadsPerCore=2 Feature="rev1" Gres=gpu:SYSTEM12:1 RealMemory=64171 State=IDLE *Issue 2:* while execution , Slurm o/p's some extra prints in the srun output user1@host$ srun --gres=gpu:1 hostname srun: error: extract_net_cred: net_cred not provided srun: error: Malformed RPC of type RESPONSE_NODE_ALIAS_ADDRS(3017) received srun: error: slurm_unpack_received_msg: [[inv1715771615.nxdi.us-aus01.nxp.com]:41242] Header lengths are longer than data received *mylinux.wbi.com <http://mylinux.wbi.com>* Regards, MS

Can't schedule on cloud node: State=IDLE+CLOUD+POWERED_DOWN+NOT_RESPONDING
by Xaver Stiensmeier 20 Sep '24

20 Sep '24

Dear slurm-user list, I have a cloud node that is powered up and down on demand. Rarely it can happen that slurm's resumeTimeout is reached and the node is therefore powered down. We have set ReturnToService=2 in order to avoid the node being marked down, because the instance behind that node is created on demand and therefore after a failure nothing stops the system to start the node again as it is a different instance. I thought this would be enough, but apparently the node is still marked with "NOT_RESPONDING" which leads to slurm not trying to schedule on it. After a while NOT_RESPONDING is removed, but I would like to move it directly from within my fail script if possible so that the node can return to service immediately and not be blocked by "NOT_RESPONDING". Best regards, Xaver

SlurmDBD errors
by Sajesh Singh 19 Sep '24

19 Sep '24

OS: CentOS 8.5 Slurm: 22.05 Recently upgraded to 22.05. Upgrade was successful, but after a while I started to see the following messages in the slurmdbd.log file: error: We have more time than is possible (9344745+7524000+0)(16868745) > 12362400 for cluster CLUSTERNAME(3434) from 2024-09-18T13:00:00 - 2024-09-18T14:00:00 tres 1 (this may happen if oversubscription of resources is allowed without Gang) We do have partitions with overlapping nodes, but do not have "Suspend,Gang" set as the global PreemptMode mode. It is currently set to requeue. I have also check sacct and there are no runaway jobs listed. Oversubscription is not enabled on any of the queues as well. Do I need to modify my slurm config to address or is this an error condition caused by the upgrade? Thank you, SS

Feature request: Max Jobs Per Minute
by Ransom, Geoffrey M. 16 Sep '24

16 Sep '24

Hello We have another batch of new users and some more batches of large array jobs with very short runtimes due to errors in the jobs or just by design. Trying to deal with these issues, Setting ArrayTaskThrottle and user education, I had a thought that it would be very nice to have a limit on how many jobs can start in a given minute for users, so if they posted a 200000 array job with 15 second tasks then the scheduler wouldn't launch more than a 100 or 200 per minute and be less likely to bog down, but if they had longer runtimes (1 hour +) it would take a few extra minutes to start using all the resources they are allowed to but not add much overall delay to the whole set of jobs. I thought about adding something to our CLI filter, but usually these jobs are asking for a runtime of 3-4 hours even though they run for <30 seconds so the submit options don't indicate the problem jobs ahead of time. We currently limit our users to %80 of the available resources which is way more than slurm needs to bog down with fast turnover jobs, but we have users who complain that they can't use that other 20% when the cluster is not busy so putting in lower default restrictions is not currently an option. Has this already been discussed and isn't feasible for technical reasons? (Not finding anything like this yet searching the archives) I think slurm used have a feature request severity on their bug submission site. Is there a severity level they prefer to have suggested requests like this? Thanks

Detailed locations for SLUG'24
by Bjørn-Helge Mevik 10 Sep '24

10 Sep '24

Dear all SLUG attendees! The information about which buildings/addresses the SLUG reception and presentations are to be held is not very visible on the https://slug24.splashthat.com. There is a map there with all locations (https://www.google.com/maps/d/u/0/edit?mid=1bcGaTiW0TNB5noQsjQ3ulctzKuqlGrQ…) but I've gotten questions about it, so: The reception on Wednesday will be held in the top floor of Oslo Science Park (Forskningsparken). Address: Gaustadalléen 21. There will be someone in the reception who can point you in the right direction. The presentations will be held in auditorium 3 in Helga Engs Hus ("Helga Eng's House"). Address: Sem Sælands vei 7. Lunch will be in the canteen in the same building. The closest subway station to both these buildings is Blindern Subway Station (Blindern T-banestasjon). Looking forward to see you there! -- Regards, Bjørn-Helge Mevik, dr. scient, Department for Research Computing, University of Oslo

Configuration for nodes with different TmpFs locations and TmpDisk sizes
by Jake Longo 06 Sep '24

06 Sep '24

Hi, We have a number of machines in our compute cluster that have larger disks available for local data. I would like to add them to the same partition as the rest of the nodes but assign them a larger TmpDisk value which would allow users to request a larger tmp and land on those machines. The main hurdle is that (for reasons beyond my control) the larger local disks are on a special mount point /largertmp whereas the rest of the compute cluster uses the vanilla /tmp. I can't see an obvious way to make this work as the TmpFs value appears to be global only and attempting to set TmpDisk to a value larger than TmpFs for those nodes will put the machine into an invalid state. I couldn't see any similar support tickets or anything in the mail archive but I wouldn't have thought it would be that unusual to do this. Thanks in advance! Jake

Slurm Remote Task Launch
by Bhaskar Chakraborty 04 Sep '24

04 Sep '24

Hello, I have a slurm job which needs to launch multiple tasks across the allocated hosts for the job. My criteria is that most of the tasks need to be launched from within the main task launchedby slurm in the launch compute node. So, if the allocated hosts are h1, h2 & h3 with h1 being the main launcher node then theinitial task, say launchTask, launched in h1 will need to launch RemoteTask1, RemoteTask2 in h2 & h3 at somepoint during execution. Can I use srun from inside launchTask to do so? If yes, what would be the syntax / args?If no, then what alternative I have other than using rsh/ssh which mayn't be available in the cluster. Thanks in advance! Regards,Bhaskar.

Best practices for tracking jobs started across multiple clusters for accounting purposes.
by Di Bernardini, Fabio 02 Sep '24

I need to account for jobs composed of multiple jobs launched on multiple federated (and non-federated) clusters, which therefore have different job IDs. What are the best practices to prevent users from bypassing this tracking?
