qtop is a command-line tool for monitoring PBS systems, especially torque. It tries to fit as much information as possible in the space of one screen by joining together the output of pbsnodes -a, qstat, and qstat -q, so it runs fine in user space. The screen is divided in three sections, reporting SUMMARY, NODES, and ACCOUNTS. Each user gets mapped to a unique letter, according to number of jobs in qstat. Symbol 0 is always the user with most R+Q+other jobs, 1 is next in number of jobs, etc. qtop uses and suppresses color mode automatically, as needed, so its output can be piped to other programs. It is very configurable.
