[HTCondor-users] CPU share handling changed with 8.6.5-1?

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi all,

after updating to ~8.6.5 it seems that the scaling fractions for the CPU
share cgroup has changed.

So far I had assumed the CPU share to be requested CPU x 100 for the
jobs' child groups with the condor parent share normally equivalent to
the global share.
Now the basic scaling factor within the child cgroups seems to be 1024, or?

Might also be a local problem at us - as also explicit 8core jobs now
end up with the same CPU share of 1024 as single core jobs but not 8192 [1]?


Cheers,
  Thomas
