Mersenne: P-1 Credit
Does anyone have any skinny on when we will start getting credit for 1. doing P-1 testing? 2. finding a factor during P-1 testing? Terry Terry S.

Re: Mersenne: P-1 Credit
I've found 2 factors so far during P-1 testing and received 0.001 years (about 8 or 9 hours) credit for each. Not much consolation as it 'cost' upwards of 100 P90 hours each to find them, but it beats getting no credit for spending the same amount of time not finding any.

Not much consolation as it 'cost' upwards of 100 P90 hours each to find them, but it beats getting no credit for spending the same amount of time not finding any. You always did get a small amount of credit for finding a factor (using trial factoring) compared with the effort that went in i.e. you got about 10x as much credit for running trial factoring unsuccessfully than for finding the "largest possible" factor in the range you were searching. I think PrimeNet credits factors found using P-1 as though they were found using trial factoring. However there is, as yet, no credit given for unsuccessful P-1 factoring effort. Don't lose sight of the fact that the purpose of running P-1 is to save time overall by avoiding running LL tests on those exponents which happen to be susceptible to P-1 factoring effort. Also, if you're running LL tests, you're certainly spending not more than 5% of your total effort running P-1 (significantly less than that if you're running double-checks), which is more than offset by the efficiency improvement between v18 and v19.
