[HTCondor-users] About choosing nodes over slots

["Bansal, Vikas" <Vikas.Bansal@xxxxxxxx>]

Hi,

I have a condor batch system available at my site.

$ condor_version

$CondorVersion: 8.2.10 Oct 27 2015 $

$CondorPlatform: X86_64-CentOS_6.7 $

I have 3200 slots on it.

100 nodes each with 32 slots.

I am wondering how jobs are scheduled to the nodes and slots.

E.g. If I have 100 jobs submitted in 1-5 minutes to the queue, how will they land up on the nodes/slots.

Will each job occupy one slot on a NEW node or will they fill up all 32 slots on one node and then move to next node and so on?

Is this configurable ? I.e. Which resource to choose first, node or slot?

Thanks for any help on this.
