That sounds a bit confuse. Note, that ghost particles only carry forces if they have interactions with locally stored particles, so most ghost particles will have zero forces. The ghost forces are initialized to 0 and just serve to collect the contributions that would need to cross a processor border. The ghost forces are then sent back to the processors physically carrying the particle.
So, you can only reliably access the forces of locally stored particles (that are in cells from local_cells) after the force computation is finished. You should not look at the forces of the ghost particles.
