whether your performance is good/expected depends on some other
parameters you have not mentioned. What time step length do you
use? What electrostatics method? What do you mean by “CPU with
5 nodes?”, I assume you are using 5 MPI ranks on a 40 core CPU?
http://arxiv.org/abs/1507.00898 is a benchmark study with larger
MD systems, however you might find your CPU configuration in one
of the tables and could at least estimate the performance for
your smaller system.
