I have completed these to the 900K/700K and am releasing. No prime was found. Very disappointing. I know it was a long shot, but these were the largest numbers I've ever tested and required a lot of resources.

Now back to my original programming, R79.

Nice work and that was a lot of it! :smile: Did you have residues that you could send?

Since PrimeGrid is managing base 2 work, I've provided the residues to them.

Why can't you complete to n=25000?

firejuggler 2012-03-23 14:33

ok i'll try to get it to 25k, but it won't be quick.

around 72600 test left, 17 seconds for one test if the speed remain the same, that's 342 hours of work.
As the speed won't remain it may take even more.

Thanks.

I was just concerned about leaving the search short of n=25000 as that is the limit that most bases are taken to when they are started.

342 hours just means that you need more horsepower! :big grin:

[QUOTE=firejuggler;293866]and here is the file containing the remaining k for 20-25000[/QUOTE]

You should recheck this file before continuing your search, lest you spend more CPU time than needed. There are 433 k's remaining in the file but there are only 425 k's remaining at n=20K.

Balancing:
787 k's remaining at n=2500
273 unique k's with primes for n=2500-10K
56 unique k's with primes for n=10K-15K
33 unique k's with primes for n=15K-20K
Total: 425 k's remaining at n=20K

I have two more cores, but they are dedicated to the Wieferich search over at PrimeGrid. I hope to add a 4-core i7 MacBook Pro by the end of September as I don't have a laptop anymore.

It is half vacation (Yellowstone) and half work. I return home from my vacation on a Saturday then fly to New Jersey the next day.

And yes, I intend to thoroughly enjoy it. I have planned a number of things for the kids to enjoy, such as panning for gold (on the way there) and searching for fish fossils (on the way home). Of course the time at Yellowstone will keep us busy as well. My uncle works in the park. I was there in 1987, the year of the fires, and got an guided tour of the park from him. We also intend to see Mt. Rushmore, Devil's Tower, and I hope to see a little of Sturgis. Although I don't drive motorcycles, it should be an interesting experience...

You sure you want to do R106 to n=25K? That's several CPU years of work. There's a reason Ian (MyDogBuster) only took it to n=10K even though he has many cores.

It's not the best idea to work on a base without having it reserved.

My suggestion: Reserve a small or medium-sized k-range such as k<10K or k<100K to n=25K, complete that, and see if you want to do more. That's how we work on huge-conjectured bases such as base 3. For R106, there are 10 k's < 10K and 97 k's < 100K remaining. 97 k's would likely keep you busy for a few weeks even if running 8-10 cores on it...a couple of months or more on one quad core.

When reserving part of a base, it's best to always reserve the lowest k's first and make it a contiguous range.

A couple of questions based on the prime that you've already found:
Are you doing this one k at a time?
How are you sieving?

I'll take k<100k to n=25k. I'm presieving each k separately using NewPGen, then kicking a file over to LLR after the current sieve file is removing less than 1 n per 20 seconds. The first file I LL'd just happened to have a prime :)
I noticed one of the files sieved to about 100 candidates, while the rest were more like 8-900 at the same depth. Any reason for this?

NewPGen is very inefficient and slow for searches on this project, especially for multiple k searches. It is not recommended for any sieving on this project. I would suggest srsieve followed by sr2sieve. You can sieve all of the k's at once for the entire n-range in a rapid fashion. See the first 3 posts in [URL="http://www.mersenneforum.org/showthread.php?t=9742"]this thread[/URL] for the software and guidelines for doing searches on this project. Some of the software and instructions may be slightly out of date but still will be very effective at getting you started on searching such a large-conjectured base.

One of the k's is just likely very low weight. Which k is it? I don't show that there are any k's that can be removed from the search due to partial algebraic factors on this base.

Another thought: I could sieve the 97 k's for k<100K for you. It'd probably take me a day or less to have them all done on 4 cores.

I know it takes a little time to get used to the sr(x)sieve series of programs.

Reserving R161 to n=100K.

c10ck3r 2012-08-10 02:32

I got several "WARNING: 39204*106^n-1 has algebraic factors"
can someone confirm?

Mathew 2012-08-10 02:57

Firstly everything is ok. What this really means is 39204 is the same as 198^2, and more candidates for this k can be removed.

Secondly this came from an old version of srsieve, which cannot remove the additional candidates just inform you they exist.

A newer version of srsieve will remove these candidates. If you are using Win-64Bit see this [URL="http://www.mersenneforum.org/showpost.php?p=295915&postcount=16"]post[/URL] to get the latest version.

gd_barnes 2012-08-10 06:32

Thanks for the detailed help Mathew. C10ck3r, your sieve file for k<100K should be ready by late Friday afternoon. It's less work than I thought. It's only taking about a day on one core to sieve to optimal depth. This means it should only take you slightly less than 3 CPU weeks or so to test k<100K to n=25K. Splitting up the k-ranges on all cores of a quad would take you < 1 week.

C10ck3r, attached is the sieve file for R106 for k<100K and n=10K-25K optimally sieved to P=120G. I went ahead and sieved all 97 k's. You can remove one k at a time using srfile with the following command:

srfile -G -d "1223*106^n-1" sieve-riesel-base106-10K-25K.txt

If you have the newer version of srfile, for removal of multiple k's at once, you can refer to a file that has all of the primes that you have already found as in:

srfile -G -d primes-file sieve-riesel-base106-10K-25K.txt

I am sieving R106 all k's>100K for n=10K-25K to ~optimum depth of P=135G.

Lennart[/QUOTE]

I assume that you are aware that there is a file on the reservation page already sieved for n=2500-25K to P=50G. It probably needs some more sieving but not a lot; maybe P=150G or 200G.

Assuming you meant S204

So close...FWIW they're only one off from each other in the alphabet...

Reserving S126 (new, ck = 766700) to n = 25k. Expect this to take a while, will provide regular status updates.

1256*148^158963-1 is prime!

Lennart has completed R151 to n=25K. 1023 k's were found prime for n=2.5K-25K; 810 k's remain; the base is released.

No I will continue at least to 100k.

I also have a sievefile to 1M

:sad:

When I first saw that, I read it as R51. That would be a nice one (along with S79) to get to n=25000.
