mpif90 wrapper compiler names are deprecated, and will disappear in a future
version of Open MPI. You should use the
mpifort wrapper compiler, instead. While they are deprecated,
mpif90 accept all the same parameters as
mpifort, and behaves the same as
mpifort, you can compile any Fortran program that uses the "mpif.h", "use mpi",
and/or "use mpi_f08" MPI Fortran interfaces.
See mpifort(1) for more details.
