Dear HTCondor-Team/Users,
We use HTCondor at our institute but keep running into conflicts
between machine owners and HTC users. It is a recurring problem that
workstations become unusably slow due to different kinds of resource
exhaustion (CPU, IO, memory, ...), when working on HTC jobs. We are
using the default DESKTOP policy, but jobs are apparently not
preempted by keyboard use or other user actions. Ideally, we'd like it
to preempt jobs on any indication of non-HTC activity on the machine,
preferably including SSH connections. Are there recommendations for
such a configuration?
One ugly workaround our users use to "free" their PCs from Condor is
commands akin to `watch -n1 condor_vacate`, but this should not be
necessary with the default desktop policy in my opinion. Is this a
known problem or just some configuration error on our side? You can
find our config files attached.
Best,
Alexander
