NAME

MPI_Type_create_indexed_block - Creates an indexed data type with the same block length for all blocks.

 

SYNTAX

 

C Syntax

#include <mpi.h>
int MPI_Type_create_indexed_block(int count, int blocklength, int array_of_displacements[], MPI_Datatype oldtype, MPI_Datatype *newtype)

 

Fortran Syntax

INCLUDE 'mpif.h'
MPI_TYPE_CREATE_INDEXED_BLOCK(COUNT, BLOCKLENGTH, 
                ARRAY_OF_DISPLACEMENTS, OLDTYPE, NEWTYPE, IERROR)
        INTEGER COUNT, BLOCKLENGTH, ARRAY_OF_DISPLACEMENTS(*),
                OLDTYPE, NEWTYPE, IERROR 

 

C++ Syntax

#include <mpi.h>
MPI::Datatype MPI::Datatype::Create_indexed_block( int count,
        int blocklength, const int array_of_displacements[]) const

 

INPUT PARAMETERS

count
Length of array of displacements (integer).
blocklength
Size of block (integer).
array_of_displacements
Array of displacements (array of integers).
oldtype
Old data type (handle).

 

OUTPUT PARAMETERS

newtype
New data type (handle).
IERROR
Fortran only: Error status (integer).

 

DESCRIPTION

MPI_Type_create_indexed_block creates an indexed data type with the same block length for all blocks.

 

ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object.

Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
