Mersenne: Re: Where is M23494381?
I has assigned that exponent to factor. But today it disappears from my Individual Account Report. I've had the same experience with some exponents assigned to me. My guess is that someone has been doing trial factoring work semi-independent of PrimeNet and has just reported all the work that they have done. My reasons for this belief is 2 fold. 1. For a long time on this page: http://mersenne.org/primenet/ there where no exponents in the range listed 21.9M to 22.0M. This has recently changed with them now all being listed as available for first time Lucas Lemer testing. 2. I had a couple of exponents booked out on one machine, these too disappeared recently but that machine has since checked in to give new end dates. They now appear there again but there are 2 differences. The booking out date has changed to the check-in date and the range the number had already been factored to has increased. He is the listing as it was just before it disappeared and how it appears now: 23492377 F 57 108.0 84.4 64.4 14-Nov-03 19:56 07-Sep-03 11:52 Dad 1800 v19/v20 23492377 F 58 1.2 134.8 102.8 27-Dec-03 13:59 Dad 1799 v19/v20 - Range already factored to has increased from 57 to 58. - Days assigned to me reduced from 108.0 to 1.2 - Date assigned to me changed from 7/9/03 to 27/12/03 (or in US date format 9/7/03 to 12/27/03) Doug. _ Unsubscribe list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Mersenne: Should I switch an exponent to another processor type?
I've currently got an exponent of the order of 20.05M running on a P4 (1.8Mhz). It has decided to run it with FFT size 1280K. It's done just over 1M iterations (and hasn't finished Stage 2 P-1 since this only runs for a few hours each night). If I'd of know that it was going to use this FFT size before it started, it would have been better for me to switch it to another processor type - since then it would have used a smaller FFT size. If I now move the saved file to another processor type would it use a smaller FFT size or is the FFT size hard coded into the save file or is this a bad idea to move the saved file for other reasons? While on the subject of FFT size where is the information stored about which FFT size tests have been run on each machine? I ask because if this is on the server then it would be a bad idea to reuse machine names. Further if you upgrade Prime95 is it a good idea to get it to rerun the tests again?
