qtop project is mainly involved in building cluster monitoring tools
qtop is a nifty command-line tool for monitoring PBS systems, esp. torque.
It tries to fit as much information as possible in your screen's real estate,
by joining together the output of pbsnodes -a, qstat &amp; qstat -q.
Output is divided in 3 sections, reporting: a) SUMMARY b) NODES c) ACCOUNTS
Each user gets mapped to a unique letter, according to number of jobs in qstat.
Symbol 0 is always the user w. most R+Q+other jobs, 1 is next in # of jobs, etc.
qtop suppresses color mode automatically, when needed, eg. try: watch -d qtop
Very large sites should try qtop|less -RS and navigate around with arrow keys.
It is very configurable, you can either modify qtop.conf or, try qtop -h.
