I have installed the MPI version of amber16 and test PASSED as manual.

But when I followed the tutorial at http://ambermd.org/tutorials/advanced/tutorial17/section1.htm

and typed the command ' mpirun -np 2 $AMBERHOME/bin/pmemd.MPI -O -i 01_min.in -o 01_min.o
ut -p ala_tri.prmtop -c ala_tri.inpcrd -r 01_min.rst'

Error come as
  Unit 5 Error on OPEN: 01_min.in

  Unit 5 Error on OPEN: 01_min.in
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.


Then I tried other tutorials,

same error come: e.g. 'Error opening unit 5: File "md_qmmm.in" is missing or unreadable'

But the input file was just saved from online tutorial.

What's wrong?

Looking forward to hear your reply soon.

Best wishes
