Last week I upgraded from Slurm 18.08 to Slurm 19.05. Since that time,
several users have reported to me that they can't submit jobs without
specifying a memory requirement. In a way, this is intended - my
job_submit.lua script checks to make sure that --mem or --mem-per-node
is specified, and will reject a job of neither of those are specified.
But here's the thing - that check should never be needed, because I have
set default value of 2 GB/CPU in my slurm.conf file, and that worked
fine up until the upgrade last week. Did 19.05 change the way defaults
are set, or is this a bug?
From my slurm.conf file:
DefMemPerCPU=2000
Any ideas why this behavior changed with the upgrade?
