Sorry, I can't made base 290 quickly. This base is hard for my computer.
I releasing this base.
Again sorry
Pre-thanks

Reserving base 6 from 120k to 150k.
Also, I am posting the sieve file for base 50 from 100k to 120k (it is sieved to 12 T). It should be ready to go for PRP/prime testing.

I'm wondering why no searches were done for n>1K for bases 56 and 58.

I ran both bases myself for n=1 to n=2500. The web page is correct for all n<=1000. I found 4 additional primes for n=1000-2500. Attached are all of the primes that I found. Here are the 4 new primes:

(56^1698-1)^2-2

(58^1720-1)^2-2

(58^1734+1)^2-2
(58^2354+1)^2-2

I would like to search the bases to n=10K but I could not make cksieve work on my machine. So I just trial-factored in PFGW for the above. Every time I ran cksieve at the command prompt, I got a Windows error message as follows:
[code]
cksieve.exe has stopped working

A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.
[/code]My machine is 64-bit, the O.S. is Windows 7, and there is 4 GB RAM. It is an Intel I7 running @ 2.67 Ghz. I have checked and even temporarily disabled my AntiVirus to make sure it wasn't being blocked.

Has anyone else had problems running cksieve?

I do not know why cksieve is crashing. This is the first that I've heard of anyone having such a problem. Does it crash immediately? What command line arguments are you passing? Can you build from source?

Yes it crashes immediately. It doesn't matter how I run it or what command line arguments that I give it. I've tried running it both at the command prompt with correct command line arguments (using exactly what you stated on your web page) and without command line arguments at all. I've tried just pressing enter on the file name. I've tried right-clicking on it and choosing "run as administrator". All attempts crash immediately.

I run all versions of sr(x)sieve on this same machine with no problem so I'm very surprised. To check the machine, I just now downloaded the latest version of srsieve. It runs fine.

You would have to give me instructions on building from source. I've never done that.

This is my only Windows machine. Do you have a Linux version?

Edit: Here is the command line arguments that I give it:

Make or Makefile are not executables so trying to execute them does not work. When I type "make" or "makefile" at the command prompt it just says:

What does "mingw64" mean? I have not compiled C programs in Windows/Linux before so you are going to have to be very basic here.

Thank you! Unfortunately the first one didn't work and gave two error messages. The second generic version did not work either but only one error message was issued. For the generic version, here is a copy-and-paste of the command that I issued and the error message:

mingw64 is an application which give you access to many of the unix command line programs that you are familiar with from Linux, such as grep and diff. It also has gcc/g++, a compiler for C/C++ code. make is another program that is bundled with mingw64 that will build libraries or executables using a makefile, which has the switches and other settings needed to build said library/executable.

mingw64 is free to d/l and install and everything that comes with it is free to use. You just need to add mingw64's bin directory to the PATH environment variable.

For your Linux distro you would need to install the packages that include make and gcc/g++ then you can build.

I assume you modified the makefile. Let me know what compile and link switches you used I would guess that you removed "-march=native". In most of my software I avoid using -march as much as possible as it reduces cross-platform compatibility, but not in cksieve as I started with a makefile used by another program. I will eventually make that multi-threaded and when I do it will not use that switch.

I changed from "native" to "x86-64" as that appeared to be the most generalized 64-bit flag I could use. That was the only change and it compiled under MinGW and the Win10 Ubuntu bash shell without any other modification needed.

The GLIBC error Gary got appears to be due to using the older version of Ubuntu. From a quick search around, it seems that one simply can't get the appropriate version of GLIBC unless you compile it yourself for the older distros.

Edit: And I set the ARCH flag to x86-64, not sse.

This was unexpected. It is the largest primeless gap for b<38 and n<=30K. It is a fairly heavy weight base and the last prime was at n=8093. For that reason I'm attaching results.

LaurV 2018-02-14 10:16

I was looking to those tables and saw that after 222 or so, the bases are not contiguous. I assume there is no search done for the missing bases, and the "higher" values just come from "people with a hobby" and not from an organized search. Because, unless I am not missing anything, I see no reason why the missing bases would not give primes. I think they do, and it should be no reason to jump from 222 to 228 (therefore missing 224 and 226) or from 2010 to 2026.

Now, the introduction done, for a week or so we were looking for an opportunity to test the new "multi-threaded" tool from Mark (i.e. mtsieve). We picked CK numbers, and we picked the base 2018. As the current year, you know? We could not make the toy run in multi-threaded mode (this is subject for another thread), but we got hooked :blush: and let it run overnight to sieve (single thread) and test with pfgw with some batch file. In the morning we had few (small) primes, and pfgw was close to testing n=12k or so.

Does it make any sense reporting it? Or we are really missing the point (again, it won't be the first time, hehe).

That is correct. If you do not see a base listed, it has not been tested. There are plenty of "base holes" to fill so feel free to reserve and test some if you would like.

I'm happy to hear that you guys are working on the multi-threaded version of cksieve.

Mark had previously asked that people only reserve and report bases if you intend to test them to n>=10K. I would like to stick with that requirement so as to not have a lot of admin work for small tests. So if you have a base that you have tested to n=12K, yes please report its results.

I know of those post and as mentioned, both of them gave no list of all primes upto n=1024, only the first one to this bound or higher ones if none was found then.
They invented the wheel perhaps, but gave no complete instructions for a whole wheel.

I'd say a good starting point for some sieve files would be bases 52, 54, 56, and 58 for n=10K-30K. I feel like P=300G would be sufficient. Although these bases are only searched to n=10K, all other bases around them have already been searched to n=30K.

Bases 364 and 368 have Carol prime found, and base 426 has Kynea prime found.

Bases 362, 394 and 472 still have no Carol prime found.

[QUOTE=gd_barnes;481132]Thanks!

I'd say a good starting point for some sieve files would be bases 52, 54, 56, and 58 for n=10K-30K. I feel like P=300G would be sufficient. Although these bases are only searched to n=10K, all other bases around them have already been searched to n=30K.[/QUOTE]

The number that I am factoring has entered LA, so I will reserve bases 52, 54, 56 and 58 for sieving, from n=10k to n=30k.

The n-range of 10k-30k has been sieved for bases 52, 54, 56, and 58 up to p = 500G, which was when the time to remove a factor became longer than the time needed to test any candidate in the files. They are included in the 7zipped file attached in this post.

Reserving base 10, n = 100k to 200k, for sieving.

Base 6 is at n = 130207. No new primes have been found yet, and I am continuing to n = 150k.
Base 10 sieving is at p = 1.05 T. Goal is to get the sieve file sieved up to p = 10 T or so (maybe less depending on the time per factor).
Lastly I have two more sieve files: base 14 for n = 30k to 50k (sieved to 1.2 T) and base 18 for n = 40k to 50k (sieved to 2 T). Both files are attached in the 7 zipped file in this post.
As an aside, when these files have been fully tested, all bases <= 20 will have been searched to n >= 50k.

Base 6 - no change in the n value since the last status update.
Base 10 sieve is at p = 4.85 T, current time to remove a factor is 1575 sec, which is slightly more than a third of the time needed to test the largest candidate in the file (~1 h 4 min).
Base 18 is approaching n = 44k, one prp has been found. I will report it once the range is complete.

I guess it's about time I found out what these critters are. <rummage rummage>

There is a most recent update on 2018-10-16 by [b]kar_bon[/b] for base 12 at [url=http://www.noprimeleftbehind.net/Carol-Kynea-prime-search.htm]Carol and Kynea Prime Search[/url]. I'm guessing the two largest ones are the newest. These would be (12^68835 - 1)^2 - 2 and (12^78858 + 1)^2 - 2.

This file is for Dylan14. It is only the n/c that haven't been tested below 1000000. You can easily generate the first line for base 2 using cksieve.

Thanks for the sieve file rogue. By the way, the start of the file is at 765831. Did you test the numbers between n=760k and the start of the file, or is that a gap that I will need to fill in?

As I stated these are the only candidates that haven't been tested, so anything below the n in the file was either removed by sieving or by testing.
