There are two things you should test:
a) Does your NVIDIA driver + CUDA setup work? Try to run a different
CUDA-based program, e.g. you can get the CUDA SDK and compile one of
the simple programs like deviceQuery or bandwidthTest.
b) If the above works, try to compile OpenMM from source with the same
CUDA version as the one used when compiling Gromacs.
Let me know if you succeed!
