The dedicated scheduler code is part of the usual HTCondor scheduler.  
While you can put this on a separate machine, perhaps to load balance,  
if your current submit machine is not overloaded, you can submit and 
manage parallel jobs from your existing scheduler machine.  If you have 
another machine available, we would first recommend to run the central 
manager components (the negotiator and collector) on a separate machine 
from the schedd, though that is not strictly required.
