[QUOTE=bsquared;586505]Yes it does, but while it seems to work for me, people have reported problems/crashes there as well.

Given the availability nowadays of WSL2 and a much better visual studio implementation as of v2.06, I am actually in the process of abandoning the mingw64/msys2 build option and code from yafu. All these different options are getting to be too much for me to maintain.[/QUOTE]

I think it is important to support other platforms. If interested I could build and test on OS X.

[QUOTE=rogue;586525]I think it is important to support other platforms. If interested I could build and test on OS X.[/QUOTE]

I just mean that I don't plan to keep building/testing on msys2 and won't be releasing any more windows executables that are produced by mingw64/msys2. I will always have a windows executable - it will just be produced by MSVC going forward. And WSL2 is another option running yafu on windows.

If you want to try to build and test on OS X please do! I will support you if I can. I've also had people express interest in getting yafu to run on apple's M1 arm-based processor. But with the heavy reliance on x86/x64 assembly code I have slim hopes of that working any time soon.

[QUOTE=BudgieJane;586520]
I would like to thank Ben for all his work so far, and would like to say thank-you in advance for future developments.[/QUOTE]

It's my pleasure, thank you. And please keep letting me know about issues; I may not always have an answer but it's how I learn. And nothing will get better if I don't know there is a problem.

What is the best way for me to contact you? PM? e-mail? Discord? Something else?

PM will work for now.

I have a problem with the output file yafu generates. It contains the input number and factors in the format:

(input#)/factor1/factor2/factor3

Apparently factordb is unable to read this format. It's not hard to change it to input#=factor1*factor2*factor3 which factordb can read, but I wonder if it's possible to have yafu output the factors in a different way?

I can't get CUDA Poly selection to work.

Anyone know what file is missing when it says "CUDA_ERROR_FILE_NOT_FOUND"? I think error messages should be made more specific/verbose.

I think the msieve sort engine is missing, here is a link to a zip file containing it:

[url]https://drive.google.com/file/d/1wGhHGffiuVS6u04N-JEfRvuBDOSzujmN/view?usp=sharing[/url]

I assume that the directory 'cub' containing sort_engine.dll has to be in the directory holding the yafu executable file.

Which version of msieve are you using? I would recommend you download the updated source code from [url]https://sourceforge.net/p/msieve/code/HEAD/tree/trunk/[/url] and build it yourself from the build.cuda.vs directory.

Edit: This is more of something you should attempt if the solution above from Brian Gladman doesn't work for you.

I'm using the most recent YAFU 2.x executable (from BSquared's GitHub), with internal poly selection. Brian Gladman's solution didn't work completely (still getting "error (line 1128): CUDA_ERROR_FILE_NOT_FOUND").

EDIT: I redownloaded YAFU from the GitHub repo, and it's working now. Must've downloaded the version that BudgieJane attached on post #196.

I think CUDA_ERROR_FILE_NOT_FOUND refers to the stage1_core_sm**.ptx file; it is supposed to be next to the executable. The sort_engine.dll file should be in a directory called cub beneath the executable.
