[gmx-users] REMD in one nodes with two processors

[Dongsheng Zhang]

David,

Thank you for your reply. I have provided replica0.tpr and replica1.tpr,
but the program looks for replica.tpr. It surprises me.

I have also tried to run 

/home/brasilia/dong/mdrun_mpi -np 2 -replex 500 -reseed -1 -multi -s
replica0  replica1 -deffnm replica -N 2 -v >& zevel 
 It doesn't work either (complains only one replica: Nothing to exchange
with only one replica). it seems the program does not recognize the
-multi option. 


Best wishes!


Dongsheng
