MPI_Group_rank(3)

NAME
     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.
