Don't use the tutorials simply to verify the installation -- that's what
the test suite is for. The manual has instructions on running the test
suite.

Your submission script is *way* too complicated. What's more is that you
are running all steps -- including the setup steps -- in the compute node.
The "typical" workflow is to do the first steps by hand on your workstation
(or interactively on the login node) -- preparing the PDB file, running
leap to get the prmtop and inpcrd file -- and then use a submission script
to run either sander or pmemd (perhaps several sander or pmemd jobs
consecutively).
Also, clusters like the one you are trying to run on are all different. I
suggest consulting your cluster documentation for how to run
MPI-parallelized programs (in general, you will need some kind of "mpirun"
or "mpiexec" command to run sander.MPI or pmemd.MPI with more than one
processor). Also try simplifying your submission script significantly so
that it only runs a single sander.MPI simulation and see if you can get it
to work. That will be easier both for you to debug and for us to help
with if you still have problems.
Good luck,
Jason
