Thanks for the info.
Here Central manager is the only dedicated submit node. And also runs
Suppose if I configure
MAX_JOBS_RUNNING = 500
It means maximum of 500 jobs can run at any time, but more than 500 jobs
say 2000 jobs can submit to the pool using condor_submit right?
Job varies from running less than a minute to 30 minutes and with the
data files around 1 mb.
Is there any way to specify maximum jobs submission at the user level,
for example each user can submit max of 100 jobs?

Without knowing exactly what your jobs are doing, it's hard to tell you
exactly, but that central manager, even if it is also the submit node,
should be able to handle more jobs than your cluster can run. I allow
each of my desktops (I don't have a single submit node) to run 150 jobs,
and I have some dedicated submit nodes with limits of 200 and 500.
The condor_config line below controls the number of running jobs from a
single submit node:
## What's the maximum number of jobs you want a single submit machine
## to spawn shadows for?
MAX_JOBS_RUNNING = 150
