If your code is multithreaded, all of the threads will run on a single 
computer. Condor does not automatically distribute your threads between 
multiple computers.

If you can break your job into discrete tasks, you might consider 
master-worker:

If you can break your job into multiple jobs (each one is a separate 
invocation of an application) you can consider DAGMan:

If you use MPI for communication between tightly couple processes, you can 
do that too:

I hope this helps.
