Better go at least to 340k, that's one of the "milestones" where LLR exe times (and FFT lengths used) become longer. If you want to find a 100kdigit prime then sieve to 425k. Also note that the bottom limit of reportable primes is currently at about 180k.

I am currently testing the following ranges: 164K to 220K => sieved + llring 220K to 500K => currently sieving Are there "better" (faster) sieving programs then NewPgen?

164K > 220K 45% complete  1 prime found (50.000 digits)

Cedric, if you could list the prime itself, it would be nice.

From now on, I only list the primes I have found on the "Post your primes you have found" pages Currently resieving the range 220000 through 500000 with Proth 0.42 Found 3000+ factors wich NewPGen initially not found Therefore I created my own Riesel.dat file Code:

Thank you Cedric, but you're right. They should be posted there. I forgot about cross posting.

13236795 done to 220k. 4 primes found
Now currently sieving to 500k. I will take this K to 1 million.

K=13236795 Status Post
For not soiling the "I'd like to help out" thread,
I open a seperate thread wich will contain info about my progress of this K. Moderators, if it is possible please move all the reply's in the "I'd like to help out" thread to here. Update Code:
: stopped sieving of 13236795 of the range 220k => 500k : started llr'ing this range => 18.000 candidates left (of the 280K potentials) : continuing sieving of the 500K => 1M range Code:
13236795*2^1671881 is prime! 50000+ digits 13236795*2^1990201 is prime! 59919 digits 13236795*2^1995161 is prime! 60068 digits 13236795*2^2155821 is prime! 64904 digits

Currently resieving the range 231k => 1 Million.
This range spans approximately 101.000 tests. Did LLR from 220k => 231 (744 tests). So llr'ing _all_ these test would take a long time. So lets say 1000 test each 23 days * 100 = 200 ~ 300 days of crunch time (12 of the 24 hours) So hopefully with sieving this range to 1 T or more?? I'll get this range to about 50.000 (or less) potential candidates. Regards,
