Ok. I suggest you try to use pmemd.MPI instead of pmemd.cuda.MPI just to see if any error messages pop up.

Respected sir,
Thank you for your response. I check all six mdout files. All are the same.

Hello Dulal,

Do you see any error messages at the bottom of your MDOUT files?

I got the following error
Checking cpin file and/or cein file.
 We are going to find DELTAGREF for a pH titratable residue using Replica
Exchange.
 The solvent pH value of replica 1 is 6.200 and was loaded from the
mdin file (001/001.in<http://001.in/>).
 The solvent pH value of replica 2 is 6.400 and was loaded from the

 The solvent pH value of replica 4 is 6.800 and was loaded from the
mdin file (004/004.in<http://004.in/>).
 The solvent pH value of replica 5 is 7.000 and was loaded from the

 The target pKa is 6.60000.
 The temperature is 300.00 K and was loaded from the mdin file (001/001.in<http://001.in/>

 According to the mdin file (001/001.in<http://001.in/>), the value of ntcnstph is 500.

 According to the mdin file (001/001.in<http://001.in/>), the value of numexchg is 10000.

 The program will try to find a range of values for DELTAGREF
automatically, as the argument -dgrefrange was not given

 AMBER execution #1: running 10000000 MD steps (5000 replica exchange
attempts) for DELTAGREF = 0.000000 kcal/mol

ERROR: The execution of AMBER using the binary

returned the following STDERR:

       The command executed was:

       mpirun -np 6 /home/srabani/Downloads/amber18/bin/pmemd.cuda.MPI -ng

       Check the mdout file (001/mdout.rep.001) to see what the error might
be. Also check if all libraries necessary to run AMBER are properly set.
       The execution of finddgref.py stopped
