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

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

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 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
