   Hey,

   I'm trying to run the simulations in CUDA on a RTX 4090, but I always get the error "All CUDA-capable devices are busy or unavailable.", even though other things using CUDA (PyTorch, ...) work fine. Running the simulations with MATLAB GPU works. I also compiled the source code myself with sm_89 set (+ DYNAMIC linking), but the error persists. Does anybody know how to solve this?

   Thanks for your help!
   Fabian

   General Infos:
   GPU: RTX 4090
   Nvidia drivers: 535.86.05
   CUDA Version: 12.2 (also tried with 11, but changed nothing)
   Code tested: example_at_focussed_bowl_3D.m (model=4)

   I ran into the same problem with precompiled binaries. Going to try to compile from source and try again.

   The v1.3 C++ binaries released here are precompiled to support up to Turing. For anything above (3090 is Ampere, 4090 is Ada Lovelace), you need to compile from source and add the CUDA architecture to the binary.

   I just compiled from source to make it work on my 4090.

   It was a problem with my cuda installation. I now installed the recommended drivers over apt and cuda 11.8 using the run file with the --toolkit option. Now everything works with the self-compiled binaries.

   I hope this message finds you well. I am currently attempting to run simulations in CUDA on my RTX 4090, but I keep encountering the error: “All CUDA-capable devices are busy or unavailable.” Would it be possible for you to provide the re-compiled binaries to help resolve this issue?

   Thank you very much for your time and assistance.
