Yes. You can. The entire program was built and was functional on CPUs well
before GPUs came into the picture. Due to the way calculations are
off-loaded to GPUs not all features available on CPUs are available in the
GPU implementation. "cutoff-scheme = Verlet" is one such example. For more
details please read http://www.gromacs.org/GPU_acceleration and the
relevant papers.
