RE: Mersenne: GIMPS in Science News

The main reason I’ve heard for people liking the Seti project is because the screen saver looks pretty. I've been thinking about this for about a month now and I really think it's time for Prime95 to get a facelift. Now, I was thinking just along the lines of having a better GUI. I.E. Have

There is a point there, but I'm sure there are a few folks who just enjoy the thrill of finding a factor. There is, we must admit, a pleasure of discovery to seeing "Mxxx has a factor: yyy" several times a month that is utterly absent from seeing "Mxxx is

Thanks for "coming clean". Hehehe...I was having fun while it lasted :) I'd call it an "unwanted feature". George, I think perhaps the easy way to handle this would be to check "UsePrimeNet" and refuse to execute AdvancedFactor assignments if UsePrimeNet=1. I wouldn't say that it's an

I appologize for the misunderstanding. The reason I was upset was not because you used ten machines to do factoring. Even two hundred machines doing factoring would not have changed the overall balance of GIMPS much. At the time of my message, I thought that you had deliberately gotten

I would urge the user concerned to report what happened and also to take any steps neccessary to prevent a repetition. I'd suggest halving the "days of work" value as a first step. The problem was caused by me testing the FactorOverride option and setting it to an abusrdly low value (56).

I would suggest that, if this person wants to climb the regular list, he switch to double-checking, switching over two or three machines a day. This would gain him credit twice as fast /and/ he would still climb in the rankings daily, or very nearly so. Why? That's what's great about

1) The program now does some P-1 factoring prior to running first time and double-checking Lucas-Lehmer tests. This will increase overall GIMPS throughput. If you install version 20 in the middle Does this mean that the exponent's that we've already done factoring on will be

I'm an impatient person in a way. I like my exponents finished in a few Me too :) That's why I factor. I've got about 8 machines factoring (from PII 266 all the way up to PIII 500). Still...someone has managed to push me down to number 4 on the factoring top 100. I'll catch up though! :)

I was reading Fermat's Enigma today and something occurred to me...would it be possible to work with a number quicker if we used a higher base? I.E. Use base 32 instead of base 10? Thus, you're doing less math. Of course, this would have to be in software because the floats can't be in that
