Re: Mersenne: Error
I saw something similar once, out of hundreds of ECM curves that I've run. It happened on the curve being run while I adjusted memory limits on the program (Version 20.4.1, April 25 file date), if I recall correctly.

Mersenne: A Curiosity: Lower Clocks And A Penchant For 500ms Disking
To All: I'm running a 533MHz Celeron in a low-end eMachines box, DCing a 53xxyyy-exponent Mersenne candidate. By using the utilities RCache and PV2000, I can knock the number of clocks/iter below 82,300,000. When I achieve this minor miracle, however, the disk light begins to pulse about twice per second -- dot dot dah for any Morsies out there. Can anyone explain this?

I had a Cyrix 300 running and I quickly realized that it's good for factoring and that was about it. I've also got a couple AMD K6 400's that are similarly pokey. They could do a double-check of around M(5M) in reasonable time, but I put them on factoring because that's just what those processors can best be doing. Now...my Pentium III 600's are kicking butt at LL testing... It's all a matter of finding the right work for the CPU you have. If all you can do is factoring with a certain system, hey, factoring is fun too!

Mersenne: errors
Hi, I appear to be getting error messages of 'input equalling output' every 4 or so days... O.K. its only a Cyrix 333...does this invalidate results? Should I switch to SETI? :) Regards, Ian (U.K.) BTW it took me 9 months to do 9763841 LL!!! _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Mersenne: Mersenne P-1 Database
Calling all P-1 factorers, I'm in the process of creating a database of P-1 factoring data for all Mersenne numbers. I have not found any other database for this information available on the 'net. There is some data kept by Will that's available, but it only goes to M(169,991)... I am collecting data for unfactored Mersennes presently, but this may expand -- depending on size of the database -- to include all Mersenne numbers not completely factored... If you're interested in seeing this database get started, and of making use of it, please send me your data. I need the exponent, B1 bound, and B2 bound. You can send the a results file if that's the easiest... Eric _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Mersenne: Error
I just got this in an ECM run on M(10079). What does it mean? Is something wrong with my machine?
