 2005-01-21, 05:31 #1 ValerieVonck     Mar 2004 Belgium 34E16 Posts I will sieve from 164000 to 220000. Is this ok?
 2005-01-22, 05:32 #2 Kosmaj     Nov 2003 E2616 Posts 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 100k-digit prime then sieve to 425k. Also note that the bottom limit of reportable primes is currently at about 180k.

Kosmaj,

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?

13236795*2^167188-1 50000+ digits
13236795*2^199020-1 59919 digits -> on the primepages
13236795*2^199516-1 60068 digits -> on the primepages

I will show this time the primes I have found.
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
Therefore I created my own Riesel.dat file

Code:
1
220000
500000
k=13236795
<factors of input file of NewPGen>
...
I then stripped the CR of this file

Regards

 2005-02-08, 18:00 #9 ValerieVonck     Mar 2004 Belgium 2·32·47 Posts 13236795 done to 220k. 4 primes found Now currently sieving to 500k. I will take this K to 1 million.

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 Primes found so far: Code: 13236795*2^167188-1 is prime! 50000+ digits 13236795*2^199020-1 is prime! 59919 digits 13236795*2^199516-1 is prime! 60068 digits 13236795*2^215582-1 is prime! 64904 digits
 2005-02-15, 17:49 #11 ValerieVonck     Mar 2004 Belgium 11010011102 Posts 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 2-3 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,
