Does that mean I have to use MPI? I got an error "mdrun -multi is not
supported with the thread library.Please compile GROMACS with MPI
support" after run "mdrun -s md.tpr -multi 10 -replex 10"
Per the error message, yes.

Hi everyone,
I tried to use Gromacs to run REMD simulation.
Firstly a set of (md#).mdp file are make and the grompp command
can generate the same amount of (md#).tpr file.
Assume # = 10,
then I tried to run REMD as mdrun -s md.tpr -np 10 -replex 10.
However, a fetal error shows as "Need at least two replicas for
replica exchange (option -multi)", what is this for? Thanks.
You have to use the -multi flag. Otherwise all mdrun does is run
md.tpr and try to do REMD with nothing.
