Dear community,
Slide 92 of the OpenMPI Sc'14 slides describes the simple migration from
mpif.h to use mpi in a Fortran application code.
However the description is not correct.
In a Fortran routine, the use-stmts (if there are) must come before (!) any
other stmts,
i.e. you cannot place the implicit none before the use mpif90 .
Correct is only this:
subroutine foo --> subroutine foo
include 'mpif.h' use mpi
implicit none implicit none
integer a, ... integer a, ...
However (for the developers of the mpi-module), you can (and should!!) employ
the implicit none -stmt inside the mpi-module itself:
module mpi
implicit none
integer MPI_...
contains
...
end module mpi

For those of you who weren't able to be at the SC'14 BOF yesterday -- and even
for those of you who were there and wanted to be able to read the slides in a
little more detail (and get the links from the slides) -- I have posted them
here:

Enjoy!
