His processes on the compute nodes are allocated through PBS, so they should
be OK.  The process on the head node is just telling them what to work on
next.

Dave,

	Please kindly let the user knows that every hour we clean up compute

node processes. If he doesn't alllocate the nodes, his testing  
processes will be killed.
	So, if he's testing for a short time, it probably doesn't matter.

Thanks,
Robin
