[slurm-users] srun --mem issue

[Moshe Mergy]

Hi Sandor


I personnaly block "--mem=0" requests in file job_submit.lua (slurm 20.02):


   if (job_desc.min_mem_per_node == 0  or  job_desc.min_mem_per_cpu == 0) then
        slurm.log_info("%s: ERROR: unlimited memory requested", log_prefix)
        slurm.log_info("%s: ERROR: job %s from user %s rejected because of an invalid (unlimited) memory request.", log_prefix, job_desc.name, job_desc.user_name)
        slurm.log_user("Job rejected because of an invalid memory request.")
        return slurm.ERROR
   end

Maybe there is a better or nicer solution...

All the best
Moshe

Subject: [slurm-users] srun --mem issue

TransUnion is running a ten-node site using slurm with multiple queues. We have an issue with --mem parameter. The is one user who has read the slurm manual and found the --mem=0. This is giving the maximum memory on the node (500 GiB's) for the single job. How can I block a --mem=0 request?

We are running:

  *   OS: RHEL 7
  *   cgroups version 1
  *   slurm: 19.05

Thank you,
