I have a Condor pool of 41 machines. Out of these I declared 5 machines
as dedicated mpi resources. If vanilla jobs are executing on these
dedicated machines because the scheduler found these machines idle and
unclaimed and a mpi job is submitted, the vanilla jobs are brutally
killed and restarted once the mpi job has finished executing. Is there a
way to let the mpi job wait for the vanilla job's completion?
If you have set up Condor as recommended for MPI jobs, you will have a
line like this in your config file:
RANK = Scheduler =?= $(DedicatedScheduler)
If you comment this out, the vanilla jobs should not get preempted.
However, it may cause the MPI jobs to wait a long time to start.
