No need for different n. As you said, it is just simple scaling. But bit levels, yes. And for Nvidia and AMD differently.

However, I am not sure the exact difference in performance -- probably on...

How does it impact the runtime for the WU?

Side question: Is it worth it, for those who have sufficient RAM, to override the -A parameter back to 32?

Ok, makes sense. That still leaves the question of why mem speed is not affecting performance. I suppose, with just 4 cores, all of the tested RAM speeds are sufficient to feed the CPU.

I am kind of confused. The quote from wikipedia says that P/VP/C are still required to do online disclosure. So who _does_ it actually exempt? And how did members of Congress benefit from it?
