monitoring myrinet fabric during a job run

Hello,

Is there anything a normal user can use to monitor the myrinet fabric, other than:
	for n in `cat $NODEFILE`
	do
		rsh $n gm_board_info
	done

Mute could be usueful, but seems to have dependencies on the ethernet line cards on
the switches working all the time, and we probably don't want normal users
talking to those cards anyways.
