You will need to reserve it to n=10k for us to show it on the pages. It is too much admin effort to show such small amounts of testing. Otherwise we'd end up with a lot of bases tested only to n=1k or 2.5k that we would have to update multiple times by the time testing eventually reached n=25k. Thank you.

You got a file pl_remain in there are all k's left with no primes found. Take that file and start sieve with srsieve.. In the readme file (when downloading srsieve) you can see how to start a new sieve with srsieve.

PM me if you not get it to work or send me the file)s) so can I start the sieves for you.

Reserving R920 to n=100k (for SRBase project) with the available sieve file [URL]http://www.noprimeleftbehind.net/crus/sieve-riesel-base920-50K-100K.txt[/URL]

Stimulated by Serge's tremendous success :wink:, I put one of my cores to base 972, with the file downloaded from [URL="http://www.noprimeleftbehind.net/crus/Riesel-conjecture-reserves.htm"]here[/URL], 15 k's, was to 25k, going toward 100k, it started with about 20 seconds per line (PFGW, is this the right tool?) and reached now close to 30k, getting slower and slower, I may let it run to 100k or stop at 50k, no idea. No primes till now. I am saving the residues (does it make sense?).

Also, trying to see what srXsieve are doing (wanted to try them for long time, but never found the time) I started "fresh" on base 967 (single k) and sieve it as high as I can (sr1sieve, after a newpgen start; I was afraid to start with srsieve, hehe; so, is sr1sieve the right tool now? is there a file already sieved for this base? or I do need to extract it from the big - 108MB - file containing all bases?). Still sr1sieving, be patient with me if I am taking a wrong path here.

Welcome to the project LaurV! :-)

For future reference, please refer to which side you are reserving; that is Riesel (-1) or Sierpinski (+1). Your link and descriptions made it clear that it was Riesel here but it will be easier to understand if you say R972 or S972 (or R967 or S967). I will show as reserved R972 to n=100k and R967 to ? for you.

You can use PFGW or LLR to do the searches. I have experienced and heard that newer versions of LLR are slightly faster. You might want to experiment for yourself. Be sure and use the "stop-on-prime" option for whichever program that you use to avoid additional searching for already primed k's.

Sr1sieve is the correct sieving program for one k. You should start sieving a range with srsieve. NewPGen is very inefficient for all searches here.

There is not an already sieved file for R967. I do not know which "big 108MB" file that you are referring to. We have no big file that contains all bases. The current team sieving effort is sieving the k's that we are working on for only bases 2 and 4.

very good point, thanks a lot! I was desperately watching for pfgw's separate log file, which he does when he finds a prime, hehe. It didn't come. What you say makes more sense.

[/quote]It does not take long to get to the right limit (over k, n) like few minutes, but I let it for a while to make sure. Then I switched to sr1sieve. I was afraid to start with srsieve from scratch, as I never used the srX sievers before. "Taking over" a file already created by a tool I knew (newpgen) was easier and somehow "error proof" (in case I was giving an idiotic command line to sr1sieve).

ok, we arrived home and checked the files. Yesterday we didn't look (sunday, shopping, blahblah) and in the morning we were in hurry to leave for work. It seems in this part of the world that [B]78*972^27907-1[/B] is prime, and it was found 48 hours ago (exactly). The testing ran all this time on the 15 k's, which means that we wasted ~48/15= 3 hours and 12 minutes testing higher n for this k (assuming they are uniform distributed in the file, we didn't check exactly how many lines have 78 in front in the file). In the next 10 minutes we will make a small script to grab out of the file all lines with "n smaller than 31915", (which we already reached) [B][U]or[/U][/B] k=78 (which we already don't need anymore). (we don't know other method to filter the file). What's left of it, we will face it against pfgw again, to see what and how. If I understood right, this is a 14 k-er now. :smile:

[edit: script done, of course, now we learned our lesson and will use "stop if a prime is found", in spite of the fact we don't exactly know how to do it, in this very moment, but we are going to investigate pfgw help]

Who is "we"? Are you more than one person? :-)

Make the header of the sieve file look like this:

ABC $a*972^$b-1 // {number_primes,$a,1}

LLR is more clear. Put the following line in the llr.ini file:

StopOnPrimedK=1

Please report all primes at the end of your search and not one at a time. For searches n>25k I'll also need the residues, that is the pfgw.out file in PFGW.

We have concerns if primes are missed so please be careful when posting final statuses for a base.

Wow, that's a huge reservation. Depending on your hardware this might well take a year or more. It might of course take only a few days if you're lucky.

[QUOTE=wombatman;389247]Reserving R1025 from n=1M to 3M.

I suspect after running a few tests that you'll want to reconsider that. I'll just put "?" in your reservation search depth.

That's fair. :smile:

I'm a fairly patient guy, so I'll probably still do it, but if something changes, I'll be sure to update here.
