[Condor-users] Condor Parallel universe and sending jobs on same physical nodes.

Dear all,
We have Condor set up for parallel universe of our cluster. 
Our cluster has nodes which have two cpus and each cpu is dual core, so
we have four cores on each node.  We use condor to run parallel jobs on
our cluster. Usually we run jobs requiring 8 to 12 cores. When a job,
for e.g. requiring 8 cores is submitted to the cluster it tends to 
select 8  cores to run the job from many different nodes, we would
ideally like to run a 8 core job on two nodes. 

Is there any way in condor to enforce this criteria for forcing parallel
jobs to run on cores on a same physical node.

Thanks in advance. I will very much appreciate any response in this
