Hello,
Using maui v.3.2.6p14
Summary:
preempted jobs (suspended) don't keep some sort of reservation on
those processors originally used but that are idle at the time because
the preempte didn't request them all.
===
I have the preemptionpolicy set to suspend and I can have low
priority jobs suspended when a high priority one is submitted. The
problem I have though is that generally the high-priority ones don't use
as many nodes/procs as the other jobs, so a job running on 40 processors
gets suspended by another one using just 5 or 10, which is OK but I
would like to somehow keep those remaining idle processors reserved so
that the preempted job can restart when the other preemptor finishes.
I'm missing something in the configuration I guess because those idle
processors are being taken by other jobs (high and low priority alike),
so the originally preempted job can never start because not all of its
processors are returned at the same time.
Say I start with a configuration from scratch, what parameters should
I be looking at for setting this up correctly ?
Thanks
David
