You would need to invoke mpirun, probably by changing the first line above
to:

$DO_PARALLEL $AMBERHOME/exe/sander -O ....

This is what is done in the test scripts, so might explain why they work,
and the script excerpted above does not. Trying to run an MPI-compiled
program without using "mpirun" will usually cause problems.
