Something like this should work:
if job_desc.pn_min_memory ~= slurm.NO_VAL64 then
-- --mem or --mem-per-cpu was used; unset it
job_desc.pn_min_memory = slurm.NO_VAL64
end

We just reject jobs if they use a setting we don't allow -- that avoids
jobs running differently than what the user believed. For instance:
-- Bigmem jobs should specify memory, no other job should
if job_desc.pn_min_memory == slurm.NO_VAL64 then
-- If bigmem: fail
if job_desc.partition == "bigmem" then
slurm.log_info(
"bigmem job from uid %d without memory specification: Denying.",
job_desc.user_id)
slurm.user_msg("--mem or --mem-per-cpu required for bigmem jobs")
return 2044 -- Signal ESLURM_INVALID_TASK_MEMORY
end
else
-- If not bigmem: fail
if job_desc.partition ~= "bigmem" then
slurm.log_info(
"non-bigmem job from uid %d with memory specification: Denying.",
job_desc.user_id)
slurm.user_msg("Memory specification only allowed for bigmem jobs")
return 2044 -- Signal ESLURM_INVALID_TASK_MEMORY
end
end
