This is from CHARMM22 paper (JPC, B, 1998, 102: 3586) page 3588
The water model used in all calculations is the TIP3P model (20)
modified for the CHARMM force field.(5) The consistency of the protein
and solvent interactions is based on the use of this water model; i.e.,
it forms part of the system description and other water models would be
Reference (5) is Reiher, W. E., III. Ph.D. Thesis, Harvard University,
1985. I cannot got it.
And if you check CHARMM22, 27, HT in TIP3P does have LJ defined, which
is different from original TIP3P.
Also check here.
So, two questions:
1. What's the impact of using original TIP3P water?
2. What can be done in GROMACS to accelerate CHARMM's TIP3P water?
