Dear Khatcharin
The error you are seeing is coming from mpirun, not from sander.MPI. Have
you verified that your mpi implementation runs correctly, do the mpi test
cases work? Can you successfully rsh or ssh to the node (even the master
node) without a password? Also check that you have the correct daemon for
mpi running (either lamboot, mpd etc...) depending on your version of mpi
etc.
All the best
Ross
