MPI_Group_compare(3)

NAME
     MPI_Group_compare - Compares two groups

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Group_compare ( group1, group2, result )
          MPI_Group  group1;
          MPI_Group  group2;
          int       *result;


     C++:

          #include <mpi.h>

          static int Group::Compare(
          const Group&      group1,
          const Group&      group2)


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER group1, group2, result, ierror

          CALL MPI_GROUP_COMPARE(group1, group2, result, 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_compare routine compares two groups.  This routine accepts
     the following parameters:

     group1    Specifies the first group in the comparison (handle)

     group2    Specifies the second group in the comparison (handle)

     result    Returns one of the following integers:

                  MPI_IDENT      The order and members of the two groups are
                                 the same.
                  MPI_SIMILAR    Only the members are the same.

                  MPI_UNEQUAL    The groups are unequal.

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