If turn around time is really that important, the servers should never be down, there should never be and bad WUs and all clients should work properly. What about all the slower CPUs? Should they be banned also? What about all the people running slow x2 cpus ban them? I can run the SMP on HT P4 and make the deadlines, I have done it before. Of course they want the results as soon possible but hey what are the deadlines for? I can do 2 SMPs with 80% time to spare before the deadline. What about the video cards? Ban all that are not 280 GTX? They are the fastest. I think this is exactly why there are dealines, if you make it in time fine, Stanford wants the work, some is faster some is slower...
