Description Marco Passerini 2015-01-13 23:09:06 MST 
We would like to use the sbatch --constraint option to specify the processor architecture within a single partition.
However, we would like to have one of the two available options set by default. Is this possible in the Slurm configuration? Or do we need to develop a job submit plugin in order to do it?
Comment 1 Marco Passerini 2015-01-14 01:00:07 MST 
Well, I got it somehow working with the job_submit.lua plugin, it was quite easy:

function slurm_job_submit ( job_desc, part_list, submit_uid )
        setmetatable (job_desc, job_req_meta)
        local part_rec = _build_part_table (part_list)

        if not job_desc.features and job_desc.partition=="parallel" then
          job_desc.features="sandybridge"
        end

        return 0
end



Let me know though if there's a way to specify the default in some other way.

That is your best solution. It is the same mechanism used by NASA Goddard for the same purpose.
