Error loading CUDA module: CUDA_ERROR_FILE_NOT_FOUND

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Error loading CUDA module: CUDA_ERROR_FILE_NOT_FOUND

Post by vitalis »

Hello F@H forumers,

I have been troubled with the CUDA support of F@H on my GTX1650 SUPER gpu. I 've tried installing latest drivers, latest CUDA toolkit, running FAHControl with root privilege and adding CUDA toolkit environment path variables but i still get an error. However the app sees the device as cuda capable which to my understanding is kind of weird...

Code: Select all

18:12:39:WU02:FS01:0x22:There are 4 platforms available.
18:12:39:WU02:FS01:0x22:Platform 0: Reference
18:12:39:WU02:FS01:0x22:Platform 1: CPU
18:12:39:WU02:FS01:0x22:Platform 2: OpenCL

18:13:13:WU02:FS01:0x22:  Using OpenCL on platformId 0 and gpu 0
Any suggestions?

FAHCore_22 brings segments of the CUDA runtime code so that every client doesn't have to install their own toolkit. Development is working on a fix which will probably be incorporated in the next revision of FAHCore_22.

I think the problem is associated with your SDK being a different version than the one utilized by FAHCore_22. If you're NOT a developer and don't need the SDK, uninstall it. If you do need it for non-FAH activites you'll have to wait for the revised FAHCore or somehow manage the env variables to manage the version discrepancies.
