One other thing I noticed is that the contents of the *_job_table has entries in tres_alloc and tres_req that seem to match types in the tres_table, but there are no mem entries. For example, tres_table= +---+-+--++--+ | creation_time | deleted | id | t

[slurm-users] MPI jobs via mirun vs. srun through PMIx.

Dear all, according to https://slurm.schedmd.com/mpi_guide.html I have built Slurm 19.05 with PMIx support enabled and it seems to work for both, OpenMPI and Intel MPI. (I've also set MpiDefault=pmix in slurm.conf.) But I still don't get the point. Why should I favour `srun ./my_mpi_program´ ove

Re: [slurm-users] MaxRSS not showing up in sacct

Re: [slurm-users] MaxRSS not showing up in sacct

Yep, the maxrss field is always blank. I just checked on a different cluster and have the same result. Jobs that completed last week even have nothing in that field. So how can I troubleshoot this? Is there a way to log the sql queries made by slurmdbd? Brian On 9/15/2019 10:29 PM, Christo
