Good idea. Add another option to srun/salloc/sbatch, update the man pages, add another field to the job submit request (data structure and RPC), the slurmctld's job structure (including save/restore of the field on restarts), perform some parsing in mail_job_info(), and that should work fine. It's not very complicated, but quite a few components are effected. If you send a patch to the list, it could be added to SLURM version 2.4 (we are only adding bug fixes to version 2.3, although you are free to modify v2.3 for your own use). >> >> Thanks, >> Moe Jette >> SchedMD >> >> Quoting Seren Soner <[email protected]>: >> >>> >>> Dear all, >>> >>> I have two little questions that I'm sure there are really quick >>> answers to, just couldn't figure them out, so I decided I should >>> finally send a question to the list :) >>> >>> First of all, can I set some nodes as "submit hosts", as in SGE ?
