Re: [slurm-users] All user's jobs killed at the same time on all nodes
A couple comments/possible suggestions. First, it looks to me that all the jobs are run from the same directory with same input/output files. Or am I missing something? Also, what MPI library is being used? I would suggest verifying if any of the jobs in question are terminating normally. I.e., is the mysterious issue which is causing all the user's jobs to terminate triggered by the completion of one of the jobs. I recall having an issue years ago with MPICH MPI libraries when having multiple MPI jobs from the same user running on the same node. IIRC, when one job terminated (usually successfully), it would call mpdallexit, which would happily kill all the mpds for that user on that node, making the other MPI jobs that user had on that node quite unhappy. The solution was to set the environmental variable MPD_CON_EXT to unique values for each of the jobs. See e.g. https://lists.mcs.anl.gov/pipermail/mpich-discuss/2008-May/003605.html My users primarily use OpenMPI, and so do not have much recent experience with this issue. IIRC, this issue only impacted other MPI jobs running by the same user on the same node, so a bit different than the symptoms as you describe them (impacting all MPI jobs running by the same user on ANY node), but as some similarity in the symptoms I thought I would mention it anyway.

I have got this all wrong. Paddy Doyle has got it right. However are you SURE than mpirun is not creating tasks on the other machines? I would look at the compute nodes while the job is running and do ps -eaf --forest Also using mpirun to run a single core gives me the heebie-jeebies... https://en.wikipedia.org/wiki/Heebie-jeebies_(idiom) On 29 June 2018 at 13:16, Matteo Guglielmi wrote: > You are right but I'm actually supporting the system administrator of that > cluster, I'll mention this to him. > > Beside that, > > the user runs this for loop to submit the jobs: > > > # submit.sh # > > typeset -i i=1 > typeset -i j=12500 #number of frames goes to each core = number of frames > (100)/40 (cores) = > typeset -i k=1 > > while [ $i -le 36 ] #the number of frames > do > > sbatch run-5o$i.sh $i $j $k > > i=$i+1 # number of frames goes to each node (5*200 = 1000) > done > > where each run-5oXX.sh jobfile looks like this: > > > #!/bin/bash > > #SBATCH --job-name=charmm-test > #SBATCH --nodes=1 > #SBATCH --ntasks=1 > #SBATCH --cpus-per-task=1 > > export PATH=/usr/lib64/openmpi/bin/:$PATH > export LD_LIBRARY_PATH=/usr/lib64/openmpi/lib:$LD_LIBRARY_PATH > > mpirun -np 1 /opt/cluster/programs/charmm/c42b2/exec/gnu_M/charmm < > newphcnl99a0.inp > newphcnl99a0.out > > > > > so they are all independent mpiruns... if one of them is killed, why > would all others go down as well? > > > That would make sense if a single mpirun is running 36 tasks... but the > user is not doing this. > > > From: slurm-users on behalf of > John Hearns > Sent: Friday, June 29, 2018 12:52:41 PM > To: Slurm User Community List > Subject: Re: [slurm-users] All user's jobs killed at the same time on all > nodes > > Matteo, a stupid question but if these are single CPU jobs why is mpirun > being used? > > Is your user using these 36 jobs to construct a parallel job to run charmm? > If the mpirun is killed, yes all the other processes which are started by > it on the other compute nodes will be killed. > > I suspect your user is trying to do womething "smart".

Re: [slurm-users] All user's jobs killed at the same time on all nodes
You are right but I'm actually supporting the system administrator of that cluster, I'll mention this to him. Beside that, the user runs this for loop to submit the jobs: # submit.sh # typeset -i i=1 typeset -i j=12500 #number of frames goes to each core = number of frames (100)/40 (cores) = typeset -i k=1 while [ $i -le 36 ] #the number of frames do sbatch run-5o$i.sh $i $j $k i=$i+1 # number of frames goes to each node (5*200 = 1000) done where each run-5oXX.sh jobfile looks like this: #!/bin/bash #SBATCH --job-name=charmm-test #SBATCH --nodes=1 #SBATCH --ntasks=1 #SBATCH --cpus-per-task=1 export PATH=/usr/lib64/openmpi/bin/:$PATH export LD_LIBRARY_PATH=/usr/lib64/openmpi/lib:$LD_LIBRARY_PATH mpirun -np 1 /opt/cluster/programs/charmm/c42b2/exec/gnu_M/charmm < newphcnl99a0.inp > newphcnl99a0.out so they are all independent mpiruns... if one of them is killed, why would all others go down as well? That would make sense if a single mpirun is running 36 tasks... but the user is not doing this.

Is your user using these 36 jobs to construct a parallel job to run charmm? If the mpirun is killed, yes all the other processes which are started by it on the other compute nodes will be killed.

Have a look in the slurmctld.log for more lines with 'REQUEST_KILL_JOB'; if they all appear at basically the same time, then it looks like uid 1007 did something like 'scancel -u theusername'. That might not be it, but that would be my first guess. Paddy -- Paddy Doyle Trinity Centre for High Performance Computing, Lloyd Building, Trinity College Dublin, Dublin 2, Ireland.

Re: [slurm-users] All user's jobs killed at the same time on all nodes
Matteo, a stupid question but if these are single CPU jobs why is mpirun being used? Is your user using these 36 jobs to construct a parallel job to run charmm? If the mpirun is killed, yes all the other processes which are started by it on the other compute nodes will be killed. I suspect your user is trying to do womething "smart". You should give that person an example of how to reserve 36 cores and submit a charmm job.

[slurm-users] All user's jobs killed at the same time on all nodes
Dear comunity, I have a user who usually submits 36 (identical) jobs at a time using a simple for loop, thus jobs are sbatched all the same time. Each job requests a single core and all jobs are independent from one another (read different input files and write to different output files). Jobs are then usually started during the next couple of hours, somewhat at random times. What happens then is that after a certain amount of time (maybe from 2 to 12 hours) ALL jobs belonging to this particular user are killed by slurm on all nodes at exactly the same time. One example: ### master: /var/log/slurmctld.log ### [2018-06-28T18:43:06.871] _slurm_rpc_submit_batch_job: JobId=718560 InitPrio=4294185624 usec=255 ...
