[HTCondor-users] Tuning condor_defrag

[Anthony Tiradani <tiradani@xxxxxxxx>]

Apologies if you get this twice, I think I sent this to the wrong address
originally.

For the moment we are avoiding large scale fragmentation of our cluster by
requesting that our stakeholders request jobs in 8 core chunks.  We only have a
small number of other jobs coming in with different request sizes.  However, we
want to be able to handle varying request sizes with greater frequency and that
requires tuning the condor_defrag to avoid slot starvation.

What solutions do other sites uses?  Preferably, I would like to have something
that "auto-tunes" the condor_defrag settings.  I have seen one from RAL and
would like to see others if sites are willing to share.

Thanks,
