Hi Rajesh,
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.
Regards,
Jyoti.

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

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
http://12.22.53.199:6080/display/CONDOR/CONDOR_HOST for details.
