OBS020 deprecated-mpi-include

warning enabled by default

include 'mpif.h' instead of the mpi_f08 module.

Why

mpif.h declares no interfaces: no MPI call is checked by the compiler, and it is deprecated by the MPI standard (4.1). use mpi_f08 gives type-checked, ierror-optional bindings.

Reported

include 'mpif.h'

Preferred

use mpi_f08
