There was a problem hiding this comment.
I managed to get it working.
For the record:
- I defined
cudss_DIRtoC:\Program Files\NVIDIA cuDSS\v0.7\lib\13\cmake\cudssin CMake - The API changed from cudss 0.7 to 0.8. It fails to compile with 0.8. Let's merge it for now and upgrade later.
- The plugin could not be loaded because the cudss DLL was not found. I manually copied it next to the SofaCudaLinearSolver DLL. Maybe something to do with
SofaCUDALinearSolverConfig.cmake.in?

Add a new CUDASparseCholeskySolver variant using cuDSS: https://developer.nvidia.com/cudss
Needs cuda toolkit 12 and cudss to be installed (not included in the toolkit itself)
Benches: (FEMBAR_CUDASparseCholeskySolver* scenes)
same with a bigger grid 76x16x16
+ clean up the cmake file.

While doing this PR, I noticed the typo on the filenames of the legacy solver "CUDACholeksySparseSolver" 🥴
