you may also be interested in using this: https://github.com/cinek810/misc/tree/master/jobsubmit/job_sane
this plugin allows you to reject jobs that are trying to use more than one node, and not the full nodes. It uses separate configuration file to allow specific users jobs not to be checked and feature combinations to force jobs placement on full nodes for heterogenous clusters. Rounding slurm job specification may not work, because users can for example specify -np to mpirun or set OMP_NUM_THREADS and "rounded" resources may not be used. Let me know if you are intersted in using this plugin. cheers, marcin 2015-02-12 4:47 GMT+01:00 <je...@schedmd.com>: > > You can use a job submit plugin to modify any job submit request.
