For your convenience, I forward the emails in mvapich-discuss concerning the missing Fortran bindings.<br>
Possibly this I can encourage you a bit, adding (as OPENMPI did it successfully) the missing explicit Ftn-interfaces in the mpi-module<br>
for those MPI-routines with parameters of "Choice"-type?<br>
<br>
At least: You may add the explicit Ftn-interface for the sbr MPI_FINALIZE . It is missing in MPICH-3.0.4 too.<br>

<br>
Thank You, Jonathan, for this hint.<br>
Indeed, the problem with the missing explicit Ftn-interfaces in the mpi-module are the arguments of "choice"-type. Fortran 95 don't like them.<br>
So the MPI-3.0 Standard document contains a complicated chapter 17.1 with these things.<br>
As a consequence, MPICH seems to have chosen the slim way omitting in the mpi-module ("use mpi") the explicit Ftn-interfaces for MPI-routines with choice-type arguments, whereas OPENMPI has chosen the cumbercome way providing the explicit Ftn-interfaces even for these MPI-routines. They succeeded.<br>
For details: In November there were some emails discussing this issue in the OPENMPI-forum.<br>
<br>
Greetings<br>

Hello Michael. My investigation turned up the same issue in MPICH-3.1.3. MVAPICH2-2.1a is based on MPICH-3.1.2 so it inherits the same behavior.<br>
<br>
Here is a snippet from MPICH's user guide:<br>
<br>
4.2 Special Issues for Fortran<br>
<br>
MPICH provides two kinds of support for Fortran programs. For<br>
Fortran 77 programmers, the file mpif.h provides the definitions of<br>
the MPI constants such as MPI COMM WORLD. Fortran 90 programmers<br>
should use the MPI module instead; this provides all of the<br>
definitions as well as interface definitions for many of the MPI<br>
functions. However, this MPI module does not provide full Fortran 90<br>
support; in particular, interfaces for the routines, such as MPI<br>
Send, that take “choice” arguments are not provided.<br>
<br>
It sounds like these are routines with ``choice'' arguments.<br>
