msgb command (1)


SYNOPSIS
msgb [-server HOST[:PORT]] [-score conf=SCORECONF_FILENAME] [-title TITLE] [-small]
DESCRIPTION
The MessageBoard server process keeps track of cluster status. SCore-S automatically locks hosts required to run a user parallel program. If SCore-S fails to lock hosts, then program execution is aborted. When the user program terminates, the lock is released. msgb is an application written in Tcl/Tk (wish) to display the current status on an X-window display. Here is the example of msgb window.
