Hi all,
Seeing that not every time a stage 1 gcd will result in a factor found, are
we not better to wait until the end of stage 2? This way, we could factor
deeper.
Perhaps this could be yet another option?
some preleminary data (on my machine at home):
Total P-1 test = 91
Stage 1 factor = 2

Maybe I'm guilty here; the very first
Based upon what I have seen so far, I want to add a vote for the addition of a side frame. Since the Header/Menu contains so many links, its really the only nice way of handling it.
All in favor of a side frame please speak up.

Well, it wasn't strictly a double post - my browser crashed just as I was
sending the second, and I wasn't sure whether it'd been sent, so I rewrote

I found that Mfactor on a 21164 was significantly
faster than Prime95 on a system which runs LL tests at
about the same rate. However the operational

Then again, if
one turned a MP machine to factoring, GIMPS might soon
run out of factoring assignments, which would not please
those with 486s and other slower CPUs whose only useful
contribution to GIMPS is factoring.

OK, so I know this might not be that warmly welcomed here, but a
few people have expressed concerns that while finding new Mersennes
is interesting, it has very limited practical value.
A while ago I heard about another distributed project called Casino-21
that would use people's PCs to run
