I fixed the problem, but I need to add the code that creates pl_trivial.txt. Right now my program is at least 4x faster than newbase.txt for that conjecture. It should be even faster after I add the trivial code.

Fixed. The outputs created by srbsieve now match the outputs from the newbase.txt script with one exception, pl_MOB.txt, pl_trivial.txt, and pl_prime.txt are not sorted in ascending k. After sorting the files and comparing, they do match.
In the test for R498, I only ran to n=10. srbsieve took about 5 minutes. prgw with newbase.txt took about 28 minutes. I strongly recommend that you use more phases if you take on that base for the simple reason that the size of the numbers grows quickly so PRP tests take much longer than for base 3. sieving is much more important than trial factoring as b and n increase.

I've just begun following tests of srbsieve version 2:
kMin: 20,000,000,001 kMax: 20,100,000,000 nMin: 1 nMax: 300 Phase 1: n=25 to n=80 Phase 2: n=81 to n=300 I'm using PFGW version 3.7.9 Also I've just begun using the starting base script following test: kMin: 20,000,000,001 kMax: 20,100,000,000 nMin: 1 nMax: 300 I'm using PFGW version 3.7.9 with f0 Regards Kenneth For version 2 of srbsieve, the percentage counter is showing accurately by moving from 0.0 to 100.0 I expect no problems to go through Phase 1 and Phase 2. Sometime during next week, we will know, not only how much more efficient srbsieve is compared to using the starting bases script, but we will also know if version 2 of srbsieve goes through each phase without a problem and if srbsieve version 2 computes the same MOB, remain and primes as the starting bases script. I'll get back to all of you as the various tests has completed Take care.

hi,
i tested the range R498; k=196306; n= to 5000 with srbsieve second version and the new bases script. i compared the files pl_MOB.txt, pl_prime.txt and pl_remain.txt and they do match. the timings are: R498; k=150000; n= to 5000 49:23:13 with srbsieve on a sbe3930k running win10 preview build 10162 R498; k=5000096306; n= to 5000 48:17:15 with srbsieve on a sbe3930k running win10 preview build 10162 and R498; k=150000; n= to 5000 ~ 83 hours with new bases script on a xeon 2630 v3 running SL6.6 64bit with f10 R498; k=5000096306; n= to 5000 ~ 81 hours with new bases script on a xeon 2630 v3 running SL6.6 64bit with f10 i sorted the files with openoffice writer and compared them with winmerge

Pronounciation
Hi all,
how is srbsieve pronounced? For me it is shrubsieve. Cheers, Willem.

Sieving took 00h 39m 04s Total testing time, using sieve and srbsieve (phase 1 and 2): 26h 58m 26s or about 6 to 7 times faster than using the starting bases script to n=300 with the f0. Even though I have no numbers to back up my following statement, then it appears that from completion of phase 2 through to completion of phase 6, the program srbsieve goes from being 6 to 7 times faster than starting bases script, to be only 2 to 3 times faster than starting bases script and sieve manually. I've no numbers to back up my statement, but maybe Axn if he sees this can come up with a universal formula to calculate the optimal sievedepth for the amount of k's and the size of the nMaxnMin in each phase. Any idea Axn? Anyone else? I should mention that I have no idea why it appears that we are loosing this much efficiency through phases 3, 4, 5 and 6 (or if I plain has forgotten how long an n=1 to n=25K range takes for base 3), but if my observation is correct, then I think it has to have something to do with our sievesettings Take care Last fiddled with by KEP on 20150718 at 17:22
