Mersenne: Factoring on a P4

2001-06-22 Thread gsi26549
For some reason, I am at a loss to explain, a v21 P4 1.4 GHz factors significantely slower that a P3 v20 700MHz. Is there a reason, and solution, for this? Bradford J. Brown - This message was sent using GSWeb Mail Services. http://www.gasou.edu/gs

Mersenne: A Basic question

I know I've hears the answer before, but, what kinds of factoring work does Primenet credit? I spend hours soing p-1 factoring (hours on a P4-1.4GHz), find nothing, and get no credit. I find a factor, and get .001 years of credit. Also, does trial (i.e. the power of two sequence before a LL t

George: What exponent ranges are fully optimized for P4 at this time? in the 4.5M range, my time is .018 sec on a 1.4 GHz. Is their a schedule for further releases. Is there a chance for further optimization for a P3? - This message was sent using
