[slurm-users] Does a --nice value given to sbatch apply to just my own jobs or system wide?

The man page for sbatch says this about the --nice option: --nice[=adjustment] >Run the job with an adjusted scheduling priority within Slurm. With no >adjustment value the scheduling priority is decreased by 100. A >negative nice value increases the priority, otherwise decreases

Re: [slurm-users] ulimit in sbatch script

Specifying --mem to Slurm only tells it to find a node that has that much, not to enforce a limit as far as I know. That node has that much so it finds it. You probably want to enable UsePAM and setup the pam.d slurm files and /etc/security/limits.conf to keep users under the 64000MB physical

Re: [slurm-users] ulimit in sbatch script

Bill, Thing is that both user and root see unlimited virtual memory when they directly ssh to the node. However, when the job is submitted, the user limits change. That means, slurm modifies something. The script is #SBATCH --job-name=hvacSteadyFoam #SBATCH --output=hvacSteadyFoam.log #SBATCH

Re: [slurm-users] ulimit in sbatch script

Mahmood, sorry to presume. I meant to address the root user and your ssh to the node in your example. At our site, we use UsePAM=1 in our slurm.conf, and our /etc/pam.d/slurm and slurm.pam files both contain pam_limits.so, so it could be that way for you, too. I.e. Slurm could be setting the

Re: [slurm-users] ulimit in sbatch script

Excuse me... I think the problem is not pam.d. How do you interpret the following output? [hamid@rocks7 case1_source2]$ sbatch slurm_script.sh Submitted batch job 53 [hamid@rocks7 case1_source2]$ tail -f hvacSteadyFoam.log max memory size (kbytes, -m) 65536000 open files

BTW, the memory size of the node is 64GB. Regards, Mahmood On Sun, Apr 15, 2018 at 10:56 PM, Mahmood Naderan wrote: > I actually have disabled the swap partition (!) since the system goes > really bad and based on my experience I have to enter the room and > reset the

Re: [slurm-users] ulimit in sbatch script

Are you using pam_limits.so in any of your /etc/pam.d/ configuration files? That would be enforcing /etc/security/limits.conf for all users which are usually unlimited for root. Root’s almost always allowed to do stuff bad enough to crash the machine or run it out of resources. If the

[slurm-users] ulimit in sbatch script

Hi, The user can run "ulimit -v VALUE" on the frontend. However, when I put that command in a slurm script, it says that operation is not permitted by the user! [hamid@rocks7 case1_source2]$ ulimit -v 82089600 [hamid@rocks7 case1_source2]$ cat slurm_script.sh #!/bin/bash #SBATCH
