MPI_Group_rank - Returns the rank of this process in the
       given group


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Group_rank ( group, rank )
            MPI_Group group;
            int *rank;

       C++:

            #include <mpi.h>

            int Group::Get_rank() const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER group, rank, ierror

            CALL MPI_GROUP_RANK(group, rank, ierror)


STANDARDS

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Group_rank routine returns the rank of the
       specified process in the given group.  This routine
       accepts the following parameters:

       group     Specifies the group (handle)

       rank      Returns the rank of the calling process in
                 group, or, if the process is not a member,
                 returns MPI_UNDEFINED (integer)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.
