If you use the -deffnm option, you do not need -s, b/c it is
already accounted for with the -deffnm.

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!

Dear gmx users,

I have trouble to run REMD on one node with two processors. The command
I used is
/home/brasilia/dong/mdrun_mpi -np 2 -replex 500 -reseed -1 -multi -s
replica -deffnm replica -N 2 -v >& zevel

the error message is:

Can not open file:
replica.tpr

you need replica0 and replica1.tpr


This error message looks strange to me. Because I have used -multi, the
program should look for replica0.tpr and replica1.tpr. Could anyone
point out what's wrong in my command?


Thank you in advance!


Dongsheng
