A memory-specific approach using dynamic provisioning would be to
declare partitionable slots using 'memory=100%'
http://research.cs.wisc.edu/condor/manual/v7.6/3_13Setting_Up.html#sec:SMP-dynamicprovisioning

And then in your job submission files include:
request_memory=<memory-requirement-estimate>


A more generic "job/cpu" oriented approach would be to use partitionable
slots with 'cpu=100%'

And then in your job submission file:
rank=Cpus

Which will heuristically prefer (partitionable) slots with the fewest
cpus already used.
