Details? Generally, what is configured as an "f77" compiler for mpi is indeed
an f90 compiler. Amber does *not* use f90 module interfaces to MPI itself,
so that "mpif77" ought to do the job. That is, as far as *MPI* is concerned,
there is no f90 code being used--this is the reason that the openmpi
configuration file has the --disable-f90 flag.
So, how did you configure your MPI? What does "mpif77 -show" report? I'm not
sure that anything will work well if you have an MPI configuration that uses
gfortran as the "f77" compiler and ifort as the "f90" compiler. Is this a
standard installation?
Having said all this, it might be better to use "mpif90" if there are lots
of MPI installations like yours that don't have a functional mpif77 compiler.
