MPI_TYPE_INDEXED(3)MPI_TYPE_INDEXED(3)NAMEMPI_Type_indexed - Creates an indexed data type
SYNOPSIS
C:
#include <mpi.h>
int MPI_Type_indexed( count, blocklens, indices, old_type,
newtype )
int count;
int blocklens[];
int indices[];
MPI_Datatype old_type;
MPI_Datatype *newtype;
C++:
#include <mpi.h>
Datatype Datatype::Create_indexed(
int count,
const int array_of_blocklengths[],
const int array_of_displacements[]) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER count, array_of_blocklengths(*),
array_of_displacements(*), oldtype, newtype, ierror
CALL MPI_TYPE_INDEXED(count, array_of_blocklengths(*),
array_of_displacements(*), oldtype, newtype, 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_Type_indexed routine creates an indexed data type. This routine
accepts the following parameters:
count Specifies the number of blocks. Also specifies the number of
entries in indices and blocklens (nonnegative integer)

MPI_TYPE_INDEXED(3)MPI_TYPE_INDEXED(3)
blocklens Specifies the number of elements per block (array of
nonnegative integers)
indices Specifies the displacement for each block, in multiples of
old_type extent (array of integers)
old_type Specifies the old data type (handle)
newtype Specifies the new data type (handle)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file.
