Thanks. We actually have SGE N1 in place. I guess didn't explain my 
interest very well. Its more related to policies than it is to load 
management software. I know that I have lots of flexibility in how to 
setup and manage queues but I'm more interested in what others have 
found  to be popular *policies* amongst users. What types of chargeback 
policies have been perceived as being "good" (or not) ? How are you 
handling priorities in terms of power users vs the average user. Are 
you using prime vs non prime policies. Again. I know that I can 
implement lots of different schemes in SGE, PBS, LSF, etc (I've been 
doing this for quite some time). I'm just looking for feedback on how 
people are establishing use and priority policies and how well received 
those policies have been. Thanks
