 2008-12-26, 08:07 #57 gd_barnes     May 2007 Kansas; USA 100111100010102 Posts I have now verified the results files for the range of n=540K-600K. All primes are correct on the top-5000 site, the 1st post of the 1st drive, and Karsten's 1st drive page. There was a small problem on the k=300-2000 page: The prime for 885*2^564282-1 is listed as 855*2^564282-1. Karsten, if you can take care of that, everything will be synced up. If the PrimeSearch site ever comes back up, I'll attempt to get all of the primes and ranges submitted for n=540K-600K. Once again, thanks to all for an excellent finish on the 1st drive to beat the year end goal by over a week. We could not have done it without everyone's efforts! The 1st drive is now considered officially complete! Look for a new sieving drive for the k=1005-2000 range in the next few hours. Gary
 2008-12-26, 09:12 #58 gd_barnes     May 2007 Kansas; USA 2×3×7×241 Posts High-priority sieving drive... A high-priority team sieving drive for k=1005-2000 has started here. Please consider helping us out as we attempt to get it sieved far enough to begin a testing drive before the 5000th-place prime reaches n=350K. Gary
 2008-12-30, 05:53 #59 gd_barnes     May 2007 Kansas; USA 2·3·7·241 Posts NPLB primes found records in 24 hours Here are some interesting records for primes found by NPLB in any rolling 24-hour time frame. All times are GMT. Most total primes found for n>260K where there were any number of top-5000 primes: 26 2 top-5000/24 non-top-5000; March 6th @ 12:01 AM to March 7th @ 12:01 AM. (Same record for up to 2 top-5000 primes.) Most total primes found for n>260K where there were 3 or more top-5000 primes: 25 3 top-5000/22 non-top-5000; March 5th @ 7 AM to March 6th @ 7 AM. Most total primes found for n>260K where there were 4 or more top-5000 primes: 19 14 top-5000/5 non-top-5000; March 11th @ 8 AM to March 12th @ 8 AM. (Same record for up to 14 top-5000 primes.) Most total primes found for n>260K where there were 15 or more top-5000 primes: 18 16 top-5000/2 non-top-5000; March 11th @ 3 AM to March 12th @ 3 AM. (Same record for up to 16 top-5000 primes.) Most total top-5000 primes: 16 March 11th @ 3 AM to March 12th @ 3 AM. These will be some records to shoot for on our new k=1005-2000 drives in the near future! Gary
 2009-01-01, 04:48 #60 gd_barnes     May 2007 Kansas; USA 2×3×7×241 Posts I've added a team drive thread for our new k=1005-2000 and n=350K-500K effort as well as a separate primes thread for that k-range. To make some room for 2 more stickies, I unstickied the 'join a team' thread. Gary
 2009-01-11, 06:24 #61 gd_barnes     May 2007 Kansas; USA 2·3·7·241 Posts I have temporarily stickied the thread about Peter Benson's search area that overlaps our upcoming 9th drive here. Please provide opinions if you would like. Gary
 2009-01-12, 12:40 #62 kar_bon     Mar 2006 Germany 1010111010002 Posts i've updated the pages for Drives #5-#7 with all data to 2009-01-11 00:00 so far. the page for Drive #9 follows the next days. i also generated a new page for NPLB-Doublechecks! all available under www.rieselprime.de
 2009-01-21, 10:09 #63 gd_barnes     May 2007 Kansas; USA 2·3·7·241 Posts We are starting a low-priority results file file-in effort for the missing results from Peter Benson's files that he sent us for k=1005-1400 for n=200K-479264. See details in this thread. Gary
 2009-01-22, 11:26 #64 gd_barnes     May 2007 Kansas; USA 2×3×7×241 Posts I have verified all of the results processed to me for the 5th, 6th, and 7th drives vs. our original sieved files. I also checked all primes vs. the top-5000 site, the 1st post in each thread, and Rieselprime.org. Other than 1 prime not listed in the 1st post of one thread and 3 missing results from a manual range that have since been corrected, everything looked great. Karsten the "official" contiguous search limits are now: k=400-600; n=615K k=600-800; n=619K k=800-1001; n=610K Gary Last fiddled with by gd_barnes on 2009-01-22 at 12:21 Reason: k=400-600 now 615K

I just completed my range and posted the results in the Drive 5 thread.

...checking it now and will edit the above post about drive completion limits when done.

Edit: verification complete.
