MPI_Type_hindexed

MPI_Type_hindexed Creates an indexed datatype with offsets in bytes MPI_Type_create_hindexed.

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Type_hindexed(int count, int *array_of_blocklengths,
 MPI_Aint *array_of_displacements, MPI_Datatype oldtype,
 MPI_Datatype *newtype)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_TYPE_HINDEXED(COUNT, ARRAY_OF_BLOCKLENGTHS,
     ARRAY_OF_DISPLACEMENTS, OLDTYPE, NEWTYPE, IERROR)
 INTEGER COUNT, ARRAY_OF_BLOCKLENGTHS(*)
 INTEGER ARRAY_OF_DISPLACEMENTS(*), OLDTYPE, NEWTYPE
 INTEGER IERROR

INPUT PARAMETERS

  • count: Number of blocks also number of entries in array_of_displacements and array_of_blocklengths (integer).
  • array_of_blocklengths: Number of elements in each block (array of nonnegative integers).
  • array_of_displacements: Byte displacement of each block (C: array of MPI_Aint, Fortran: array of integer).
  • oldtype: Old datatype (handle).

OUTPUT PARAMETERS

  • newtype: New datatype (handle).
  • ierror: Fortran only: Error status (integer).

DESCRIPTION

Note that use of this routine is deprecated as of MPI-2. Use MPI_Type_create_hindexed instead.

ERRORS

* MPI_Type_create_hindexed * MPI_Type_create_struct * MPI_Type_indexed
