[slurm-users] [Slurm 18.08.4] sacct/seff Inaccurate usercpu values

[Michael Robbert]

Andreas,

Look again. I just looked and a commit to the source code was posted to 
the bug yesterday afternoon. It looks like that patch applies to the 
cgroup plugin. It won't show up until the next release, but at least 
there is a fix available.
