p-1 = 2 * 3^2 * 71 * 263 * 9209 * 11383 * 90847 * 1130117

B1=1M B2=100M

you realize that by raising the B1 by 131K yo ucould have found it without performing stage 2

How much time (percentage) would it have saved?

Which would have been better?
Raising B1 by 131K, or lowering B1/B2 by a factor of 10?

[Greenbank]

But how would I have known to do that?

You've got to set bounds without knowing what the factors will look like.

If I'm not mistaken, Prime95 suggests a B2/B1 ratio of around 20 for B1 values at 1,000,000.

Yup that's always the point...

One could also say, you could have simply taken the number

67607*2^202131+1

and divided it by

Seriously though, what were your memory requirements like for the stage2 portion. Also time to complete for each stage, a 1:100 ratio for B1:B2 seems a little high but it works.

Are you doing stage two with prime95 have they married the two clients yet.

It was a windows box that wasn't networked and that I would only visit once a week or so. So I wanted to give it a big chunk of work without worrying about it, hence the large bounds.
