Funny you should mention that... I just got a prototype working on my GTX 1050. It's about 20 times faster than the CPU version. Probably still a few weeks out before it's production ready though.

Yep, results should be that much quicker. It works with the same exact WU inputs. On my test case, the CPU time was 13000 sec, the GPU time was 500 sec.

I will open a new thread in the next several days to post more info, and maybe put a beta version out there.

After all these years, we finally have our first GPU app. It's only a beta version for 64bit linux with Nvidia GPUs. Support for other platforms and GPUs will be coming soon.

If you'd like to help test this app, you will need to check the "run test applications" box on the project preferences page. I generated a special batch of work for this app from some older WUs that I have truth for. This will help to find any potential bugs that are still there.

A few potential issues:
1. This was built with the Cuda SDK version 10.1, so it uses a relatively new Nvidia driver version and only supports compute capability 3.0 and up. If this affects too many users out there, I will need to rebuild with on older SDK.
2. I was not able to build a fully static executable, but I did statically link the ones most likely to be a problem (i.e. pari, gmp, std c++)

Please report any problems. I am still relatively new to the whole GPU app process, so I am sure there will be issues of some kind.

Also, feel free to leave comments regarding what platform, GPU, etc I should concentrate on next. I was thinking I would attack linux OpenCL (i.e. ATI/AMD) next as that should be a quick port of what I did with Nvidia. I think the windows port will take much longer, since I normally use mingw to cross-compile but I don't think that's compatible with the nvidia compiler.

Ist nur für Linux, man muss den Nvidial-Treiber Version 418 haben und unter den Einstellungen Testanwendungen erlauben.
Standartmäßig war bei mir im Repo (Ubuntu) nur Version 390 drin.
Habs dann mit dieser Anleitung geupdatet:
