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
- 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.
