Thanks Gerrit for the response. I checked out the energy group option and
it reports the LJ, Coul-SR and Coul-LR. 

I guess the SR/LR is not splitted by the real space of k-space. Perhaps it
is for the reaction-field method when handling the electrostatic? I notice
that the Coul-LR are exactly zero in my simulation as reported by Gromacs.
