Thank you for your reply and the pointers. It sure helped. However, I
think in a grid infrastructure and assuming that a particular node will
report to many central managers, it is hard to envision *all* the
values for CONDOR_HOST beforehand. In other words, if a node comes
alive, it should be dynamically inducted into a condor pool based on
some heuristics (e.g., locality), as opposed to hardwiring the condor
control manager that it will report to.
I am not sure if my point makes sense here. Please let me know your views.

When you say "monitored/managed", do you mean the Condor system or a
third-party management software? I'm assuming it is the former. Check
for information about the Central Manager

Resources report to the collector, which then works with the negotiator
to schedule jobs. All you need to do is use the proper value for
CONDOR_HOST in the config file of the new "node". See
