As far as I have been able to determine, they're all in favor of more crunchers at this time. Since they're very strict about the homogeneous redundancy thing, the wider variety of boxen they get, the better for all the users. That's what started this thread. I need folks with the same CPU/OS combination to cross-verify my results and vice versa.
The current major problem, AFAIK, is that they're having to use longer WU's to get better precision and there's no checkpointing. We had this problem early on with FAD, as some may remember. If you need to reboot (or get rebooted) you lose your current progress. WU's run 2-6 hours, give or take, depending on your horsepower. They're having major grief from the compilers and libraries they have to use.
Really, we'd love to have you in. PM Bok for the invite code and that should do it. If you get the code and it still won't play ball, let us know!
