README for WOL


wol		- the actual wol script
wol.init 	- the init script
ether-wake.c	- the ether-wake program.  

The install.sh script will copy files to appropriate
locations and configure the wol script to start
automatically.


The wol script will power down nodes which have been idle for about
2-5 minutes, but always leave one IDLE node up to prevent the
node from bouncing and also to prevent jobs from waiting on the
queue and frustrating users.

If a node is UN-KNOWN, rather than DOWN, it will not be able to power
it back up.  This helps work around nodes with hardware failures.


NOTE======================

WOL is not currently suitable for parallel environments as
it wakes nodes one at a time and cannot query the batch job
manager about waiting parallel jobs.

Newer versions should resolve this.
