MPI_GROUP_TRANSLATE_RANKS(3)MPI_GROUP_TRANSLATE_RANKS(3)NAMEMPI_Group_translate_ranks - Translates the ranks of processes in one
group to those in another group
SYNOPSIS
C:
#include <mpi.h>
int MPI_Group_translate_ranks ( group_a, n, ranks_a,
group_b, ranks_b )
MPI_Group group_a;
int n;
int *ranks_a;
MPI_Group group_b;
int *ranks_b;
C++:
#include <mpi.h>
static void Group::Translate_ranks(
const Group& group1,
int n,
const int ranks1[],
const Group& group2,
int ranks2[])
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER group1, n, ranks1(*), group2, ranks2(*), ierror
CALL MPI_GROUP_TRANSLATE_RANKS(group1, n, ranks1(*), group2, ranks2(*), 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_translate_ranks routine translates the ranks of processes
in one group to those in another group. This routine accepts the
following parameters:
group_a Specifies the first group (handle).

n Specifies the number of ranks in ranks_a and ranks_b arrays
(integer).
ranks_a Specifies an array of zero or more valid ranks in group_a.
group_b Specifies the second group (handle).
ranks_b Returns an array of corresponding ranks in group_b. When no
correspondence exists, returns MPI_UNDEFINED.
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file.
