Thanks for your replies, Mark. What do you think about the current DispCorr option in gromacs? Is it worth it trying it? Also, I wonder whether using DispCorr for LJ + PME for Cb justifies reducing the cutoff for non-bonded to 1 nm with the CHARMM force field, where 1.2 nm is usually recommended.

Secondarily, one could use the same cut-off for LJ and electrostatics,
and treat their respective lattice components however you like. This
simplifies implementations for computing short-ranged interactions,
while facilitating iso-accuracy load balancing across heterogeneous
compute units.

Hi,
What is LJ PME? I googled it and got this publication?
http://pubs.acs.org/doi/abs/10.1021/ct400146w

So, LJ will not be cut off at some r, but you will have a real+fourier
part
similar to electrostatics. Is that LJ PME? What are the advantages?

Hi!

Just wondering whether gromacs has (or plans to implement) a correction
for the loss of long range LJ interactons? Something similar to
LJcorrection in NAMD or IPS in CHARMM.

Thanks!
