Hi Hector,
Are you running AMBER 16 here with the latest patches?
What does nvidia-smi report?
What does nvcc -v report?
You shouldn't need to do any of these hacks, especially the soft link to the libcuda.so library - that's just going to mess things up and complicate debugging more.
All the best
Ross
