[mvapich-discuss] WG: missing Fortran bindings in MVAPICH2-2.1a

[Jonathan Perkins]

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.

Here is a snippet from MPICH's user guide:

    4.2 Special Issues for Fortran

    MPICH provides two kinds of support for Fortran programs. For
    Fortran 77 programmers, the file mpif.h provides the definitions of
    the MPI constants such as MPI COMM WORLD. Fortran 90 programmers
    should use the MPI module instead; this provides all of the
    definitions as well as interface definitions for many of the MPI
    functions. However, this MPI module does not provide full Fortran 90
    support; in particular, interfaces for the routines, such as MPI
    Send, that take “choice” arguments are not provided.

It sounds like these are routines with ``choice'' arguments.
