I (think I) have provided gribozavr with the neccesary equipment to continue the project. If not, please tell me.
Good luck! OH

Thanks, Omboo! I hope project will go on well!
I have set up a web site for stats on 5gigs.com free hosting service. It has support for Perl, PHP and SSI, so I can add some serverside scripts. Suggestions are welcome! http://ohmdpp.5gigs.com/ ohmdpp stands for one hundred million digits prefactor project (they don't create subdomains starting with a digit).

1)It seems that the wide ranges are not on. Do you plan to put them on soon? 2)"For the wide factoring we use the batchfunction of Factor3_2, which can be downloaded here." Here=where? 3)"For the deep factoring we use Factor4, which can also be downloaded here." Again, here=where? 4)Do you plan to direct the interested ones to some instructions on how to participate?

Excuse me, the page is not finished yet. But I have added the most important thing  deep exponent stats (or it will become a mess soon). I will add wide ranges (todo :) ). I also plan replacing this static html page with perl script which generates tables on the fly from the database. The database will be shared with my C++ program, which is almost finished. It will be able to store and check factors, manage exponent bit depths and reservations. Of course, database is easily parseable plain text. I will put the source here as soon as it will be finished.

Will you add the option to create teams?

Can anyone suggest a way to count CPU time? Or we could count workunits: one WU 2^712^72 = two WUs 2^702^71 = four WUs 2^692^70 = eight WUs 2^682^69 = sixteen WUs 2^672^68

Some news:
We have factored all deep candidates to 2^72 I want to make an announcement of a program for managing data on factoring mersenne numbers. The data will be held in database which has a very clear (and extensible) text format: Code:
/* * Yes, it can handle comments. * Exponent without a factor */ exponent { exponent: 332193859; work { worker: "unknown"; start_bits: 1.000; end_bits: 68.000; done: true; }; work { worker: "gribozavr"; start_bits: 68.000; end_bits: 70.000; done: true; }; work { worker: "gribozavr"; start_bits: 70.000; end_bits: 72.000; done: true; }; work { worker: "gribozavr"; start_bits: 72.000; end_bits: 73.000; done: false; }; }; /* Exponent with a factor */ exponent { exponent: 332193817; work { worker: "unknown"; start_bits: 1.000; end_bits: 60.000; done: true; }; work { worker: "ltd"; start_bits: 60.000; end_bits: 67.000; done: true; }; factor { factor: 154469782343413971431; worker: "ltd"; }; }; Code:

Taking M332192897 from 72 bits to 73 bits.
Edit: I'm using factor4. Carlos Last fiddled with by em99010pepe on 20051223 at 20:12
