[slurm-users] Restrict user not use node without GPU

[Paul Raines]

I do this via code in  job_submit.lua

function slurm_job_submit(job_desc, part_list, submit_uid)
     -- Must allocate GPU if on a GPU partition
     if (job_desc.tres_per_job == nil and job_desc.tres_per_node == nil) then
       if (string.find(job_desc.partition, "rtx8000")) then
         slurm.log_info("slurm_job_submit: for user %u, no GPU requested in rtx8000",
           job_desc.user_id)
         slurm.log_user("FATAL: you must request at least one GPU in the rtx8000 partition");
         return slurm.ERROR
       end
     end
     return slurm.SUCCESS
end


Then set JobSubmitPlugins=lua in slurm.conf

I cannot find any documentation about what really should be in 
tres_per_job and tres_per_node as I would expect the cpu and memory
requests in there but it is still "nil" even when those are given.
For our cluster I have only seen it non-nil when GPUs are requested.
