Reply To: gpu usage question
I just want to confirm that I had the same problem. Commenting out “using namespace olb::util;” did the trick, I did not need any further adjustments.
Ubuntu 22.04.3 LTS
g++-10 10.5.0
nvcc V11.5.119
CUDA Version: 12.2
CUDA_ARCH 75 (Quadro RTX 5000)
I used the gpu_only.mk configuration and added the -ccbin=g++-10 option to nvcc
