##  The NEGOTIATOR_POST_JOB_RANK expression chooses between
##  resources that are equally preferred by the job.
##  The following example expression steers jobs toward
##  faster machines and tends to fill a cluster of multi-processors
##  breadth-first instead of depth-first.  In this example,
##  the expression is chosen to have no effect when preemption
##  would take place, allowing control to pass on to
##  PREEMPTION_RANK.
##
##  Break ties by looking for machines that have Idle longer than others
##  and use them first. Also try and use faster machines before slower
##  machines and assign jobs to separate machines before we start
putting
##  two jobs on a machine.
NEGOTIATOR_POST_JOB_RANK = (((Activity =?= 'Owner') * (State =?=
'Idle')) * 1000000000) + ((Activity =?= 'Unclaimed') * 100000000) +
(KFlops * 0.001) - (VirtualMachineID * 10)

If you just want breadth-first filling:

NEGOTIATOR_POST_JOB_RANK = (RemoteOwner =?= UNDEFINED) *
VirtualMachineID

That'll fill the higher VMs first.
