[slurm-users] Lua jobsubmit plugin for cons_tres ?

[Renfro, Michael]

Snapshot of a job_submit.lua we use to automatically to route jobs to a GPU partition if the user asks for a GPU:

All our users just use srun or sbatch with a default queue, and the plugin handles it from there. There’s more detail in an old slurm-users posting of mine from last fall.

We do this via looking at gres.  The info is in the job_desc.gres
variable.  We basically do the inverse where we ensure some one is
asking for the gpu before allowing them to submit to a gpu partition.

Hi All,

I am trying the newest SLURM 19.05 and its new cons_tres plugin.
Is there a way to handle its new GPU options in Lua job submit plugin?
That is, something like "detect if a job has ‹gpus-per-node, assign it to
a GPU partition"?

Thank you very much in advance!
