Does anyone out there have any recommendations for which parameters to tweek 
on an 11/780 do handle periods of have CPU usage?

Don't suggest the Dynamic Load Balencer as here is the background.

System is used as a electronic mail, electronic bulletin board for 
administrative use and for hard research work.  An 8650 is on order and is 
schedule to arrive in March and all research work will be moved to the 8650 
leaving on the electronic communications on the 780.

Currently whenever the hard researchers start gearing up and doing several 
compiles and heavy analysis runs the response time goes way down and the mail 
people get frustrated.  I would like get the system to let mail and such small 
cpu items go in and do what they need when they want and let the crunchers 
take up all the slack (not compete with the crunching).

Some of the people doing the crunching are also people using the admin 
electronic messaging, so I can set the priority down on their accounts.

I don't want to but the Dynamic load balancing software that is available for 
a problem that should only be around for a few of more months.

I am wondering what parameters should be tweaked to balance out the system.

Please send responses to me.
