Hi Beth,

Use qstat -urg, qstat -ext, and qstat -pri to show the different factors 
contributing to the priority (you can actually use all of them together, and 
make your window reeeeaaaallllllllyyyy wide :^)

You can also tack on '-r' to see details on the resource urgency factors.

Regards,
	Charu
