I have the same problem as Dylan. I have a system with Windows 7 x64 and GeForce 1080. CUDA 10 is installed here. After compilation from sources I get "Class problems. Factor divisible by 2, 3, 5, 7, or 11" error on any worktodo.txt when try to run mmff.

Sorry if this is considered a necropost, but since Jerry (flashjh) has been contacted recently for CUDAlucas (per this post by Serge) and he built the previous builds of mmff for Windows, perhaps we should contact him to see if he can get mmff to compile correctly for higher CUDA levels (so that me and newalex can use it)?

I succeed at compiling mmff with CUDAv10.1 toolkit and Microsoft Visual Studio 2012 on Windows 10 without class problems. Thanks for clues provided by nomead! Attached file contains Makefile.win I used and the compiled Windows executable.
I tried a few test cases: Code:

I have the same issue with my GTX 1080. kriesel indicated I needed a CUDA 8 build to run on Windows 10 v1903 x64. The installed driver set is CUDA 10.x. None of the ones posted will run, or so it seems.
I saw a recommendation to use CUDALucas to perform a memory test on my GPU. I did. There were no errors.

To test the full ram, don't have anything else running on the gpu at the time. If it's the display gpu too, that might be a factor. Use nvidiasmi.exe to see what's running on the gpu and using its ram. Last fiddled with by kriesel on 20200324 at 16:16
