Since no one else has responded to this yet, I will. F@H really shouldn't be a security problem. It uses the same ports http uses for sending information back and forth. I don't know what your Atom processor can do, so that's something you'll have to determine for your particular model. But you can certainly download the vanilla Linux console client and run that. From there you can determine what else may be possible.Edit

. It says the D510 has 2 cores and 4 threads. I'd try -smp 4 on that thing just to see if it would get done in time. If not, then oh well, but you can do the calculations from reading the frame times. And if it can't finish on time, you can run 4 separate F@H processes, which should produce a noticeable amount of points, anyway.
