Reserving R145 to n=100k (25-100k) for BOINC

S122
 
S122 tested to n=700K - nothing found - continuing to 1M

carpetpool 2016-12-30 08:44

New to this project, I will start by reserving S223 to n = 75k for all k values < 1000.

Edit: May take a while. (I may just do up to 50k I will let everyone know the current progress afterwards, I will continue to hold the base reserve) With NewPGen and PFGW only.

Since you are new on this project why dont you start with smaller steps?
Take base with few K left, make sieve ( that will dramatically decrease number of candidate to test) , and make test with LLR rather then PFGW.

Sr2sieve is far more faster any efficient then NewPgen, and you can sieve many K of same base in same time.

"May take a while" and "may just do up to 50k" and using "NewPGen" are all big red flags coming from a new person. We never use NewPGen on this project. It is far too old and inefficient. Regardless it would be a big mess for the project if we had all of these large-conjectured bases searched to different depths. To get started please reserve an entire base that you can complete within a month. Perhaps a base with 2 or 3 k's remaining for n=100K-200K. Use srsieve/sr2sieve for sieving and LLR for primality testing.

Actually we do use newpgen to build the input files to srbsieve.

Good point. I will un-reserve S223 for now. S15 seems adequate. Any other suggestions?

MisterBitcoin 2016-12-30 18:16

There are a lot of other bases with only 1 k left, they can be a good point to start with.

Check [URL]http://www.noprimeleftbehind.net/crus/Sierp-conjecture-reserves.htm[/URL] (for Sierp site)
or (easier) there: [URL]http://www.noprimeleftbehind.net/crus/tab/CRUS_tab.htm[/URL].

You should pick a Base which contains a sieve-file, sieving S15 will take some time (~2 weeks on 24/7)


All times are UTC. The time now is 23:01.
