[HTCondor-users] condor cgroup hierarchy wrt systemd managed slices

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi all,

quick question - but in principle the condor job cgroup hierarchy lives 
outside of the systemd managed slices, or?

I have tried to force the job cgroup slice underneath the 
condor.service, but have not managed to get them into a clean(??) 
hierarchy as such (where the condor.service lives in the system.slice of 
systemd)

i.e., I had tried to tinker with the condor base cgroup [1] and maybe 
get the daemons in a dedicated slice with ensured resources and the jobs 
underneaths in the hierarchy with their resources managed by Condor (and 
relative to their parent).
However, I am not sure, if/how I can actually manage to get the job 
slice, spawned by Condor, to be rooted under the service slice for 
condor spawned by systemd. I.e., like a drop-in for the condor.service 
with a dedicated `[Slice]` section - and than tune BASE_CGROUP accordingly?

Maybe somebody has already adjusted their hierarchy in a similar manner 
and got it working?

Cheers,
  Thomas
