Sorry I don't have a answer for your HT question, but I'm also curious if it's better to run work units with expiration dates or run the smaller ones that don't have expiration dates. Most of the computers I have on the project are "decent", but aren't on 24/7....they are on maybe 40-50 hours a week.
If you run a P4 2.8 (just an example) on units with no expiration will you get roughtly the same weekly output as you would if you ran larger units with expiration dates.....or is there some sort of bonus for running larger units? I know the smaller units are like 30-40 points and they take 12-24 hours to run any how.
