bWatch is short for Beowulf Watch. It is a Tcl/Tk script designed to watch the load and memory usage on all of the nodes in a beowulf cluster. bWatch does not require root access, and can be run by any user on the system as long they can execute rsh to all other machines. An example configuration file can be found at /usr/doc/packages/bwatch/bWatchrc.tcl.sample.
