Hello,
mpirun is NOT used during installation. mpif90 and mpicc are used during
installation as the compiler wrappers to invoke the desired compilers and
link to the proper mpi libraries in a 'blackbox' sort of way. mpirun is
only used during MPI execution in amber. You should make sure that your
environment is set up to use the mvapich that you want. Try typing "which
mpif90" to see exactly which mpi installation you're using. You can use
mpi-selector to choose an mpi installation, and this should automatically
set up your environment to use that MPI.
Your email sounds like it does not allow users to run mpirun interactively
(i.e. typing it on the command-line) and it is only available to run when
submitted to the queue (though i may be wrong). Have you been trying to run
interactively or submitting to the queue? Your system administrators should
be able to help you get your environment set up correctly to build amber.
Good luck!
