[QUOTE=Uncwilly]I believe that we are back on track now.

[url]http://www.geocities.com/onehundredmdpp/index.htm[/url] should be upto date.[/QUOTE]

Uncwilly, your page has some dead links:

where you wrote "www.gimps.it" you should set "www.moregimps.it" :-)

[QUOTE=Uncwilly]We have with GIMPS/PrimeNet officially working on the 10M digit issue and Luigi's Operation Billion Digit working toward 1,000M, there seemed to be a gap. Nobody has organized the work for the 100M digit prime.

So here is what I suggest.

We start working on the 100M digit range.

Using Luigi's Factor3_1 and Factor3_1b we can help clear the way for P-1 and L-L that shall follow.

I have done some preliminary work in factoring the range starting with M332192831 (the first prime expo. that will yield a 100M digit number). Starting here and working up to higher expos seems wise. If we can get a good projection of where the Mersenne prime might be, based upon the 1.47p rule, we can apply effort there, too.

I would like to suggest doing batch work. We can work in ranges and report results back etc.

More thoughts later. Anyone who wants to help speak up.[/QUOTE]+

Reserving next range on MDPP site
 
I'm working on the range 333100000-333199999, up to 50 bits. I grabbed the worktodo file off the MDPP site. Is this search still active?

I'm running a P3-500 on it, so the range should be done fairly quickly. If this search is dead, I'll waste my time on the Billion search instead.

I need to hop back in the driver's seat. I have been away from this project a while. It got to the point that there where just 1.5 interested parties.
