Re: [HTCondor-users] Run Slurm as "guest" on a HTCondor pool?

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi Steffen,

just an ad hoc idea: if eviction is not the primary requirement, you 
might be able to adjust the allocated cpu weights to each of your batch 
system units (and hoping that memory is not getting tight) and create a 
frankenworker with both batch systems stitched together...

I.e., move both the condor and the slurm service slice in a common/new 
sub-branch in your system cgroups - and assign each a cpu weight (and 
maybe memory.* caps) so that they have a 50:50 ratio (or what your job 
mix would look like) - so that they each can only consume up to their 
assigned ratio. You would also have to ensure, that the condor 
base_cgroup for the jobs and the slurm step job thingy are also placed 
in their corresponding cgroup branches.

Might be a tad hacky - but could allow for some kind of coexistence...

Cheers,
  Thomas
