Re: CUDA error cudaStreamSynchronize(stream) and CUDA error in ComputeBondedCUDA

[Peter von Kaehne]

I do not know if this would work with this kind of computation but I would suggest you try and run the programme under gdb. Nvidia suggests CUDA-gdb for this purpose CUDA-GDB :: CUDA Toolkit Documentation docs.nvidia.com So, I think this is the way to go. You should be able to figure out even without great knowledge of this kind of thing where the error lies - in your main programme or in a library.  The whole thing is, I guess, so niche that you need to do some work to narrow things down more for others likely to show some interest. As a guess I would say that a library was updated and your programme does not check on that but struggles (and fails) now.  Peter
