Huh. We all have different RP counts, for the same type of assignments. I guess it depends only on the RAM available then. Perhaps mod could move these posts to P-1 thread where we can get an explanation from the math guys?

I've rarely seen this kind of thread digression get moved (though it happens with other sorts.) Consequently, I've posted a Thread Continuation in Primenet>P-1 factoring anyone?

Hope this gets some more people involved.

I have been given (thanks to Mike) moderation access to this sub-forum.

So I've moved the appropriate posts to this new thread (and learned a bit more about how the forum system works).

That seems.... fast. What CPU(s?) do you have in there? What bounds is it choosing?

It's a dual CPU Opteron 6272 with 32 cores. Waiting on Windows 8 for better CPU scheduling.

Thanks for putting us back on track.

I'll let you know when I get home from work.

Many thanks, chalsall! I was unaware, or had forgotten that you have that ability.

EDIT: The new thread is a much better idea, too.

You are most welcome.

Now, might you continue the discussion you were wishing to hold when you asked for the record of the discussion to be moved?

Well, actually that was me

He just took the prerogative. (The reason I asked about the P-1 thread 'over there' is because those who can answer our questions are more likely to lurk there.)

You have the floor...

Speak.

I had (and have) nothing to say.
