Hi Amanda,
This sounds like the installation you have of Amber 8 is broken. It is
probably best to speak to the person who installed it and find out what they
did. Did they successfully run all the test cases after completeing the
compilation?
Also note that if the executable was built for mpi you cannot use it for
single processor runs where you don't use mpirun to run the code. I suggest
that you ask your administrator to build you a complete single processor
version of AMBER 8 in a different directory. Make sure they run all of the
tests to verify that it was built correctly.
All the best
Ross
