[gmx-users] some question about REMD

thank you all the same. I saw many people use Amber for REMD and few 
people use Gromacs for REMD and the parameters is not easy reachable. 
However, what I found is that Amber use cutoff=999

I am just wondering, shall I also use such big value for the following?

rlist = 999; short-range neighborlist cutoff (in nm)
rcoulomb = 999 ; short-range electrostatic cutoff (in nm)
rvdw = 999 ; short-range van der Waals cutoff (in nm)

thank you very much
