MPI_Type_create_hvector - Creates a vector (strided) data type
with offset in bytes.
#include <mpi.h>
int MPI_Type_create_hvector(int count, int blocklength,
MPI_Aint stride, MPI_Datatype oldtype, MPI_Datatype *newtype)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_TYPE_CREATE_HVECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE,
NEWTYPE, IERROR)
INTEGER COUNT, BLOCKLENGTH, OLDTYPE, NEWTYPE, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) STRIDE
USE mpi_f08
MPI_Type_create_hvector(count, blocklength, stride, oldtype, newtype,
ierror)
INTEGER, INTENT(IN) :: count, blocklength
INTEGER(KIND=MPI_ADDRESS_KIND), INTENT(IN) :: stride
TYPE(MPI_Datatype), INTENT(IN) :: oldtype
TYPE(MPI_Datatype), INTENT(OUT) :: newtype
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
- count
- Number of blocks (nonnegative integer).
- blocklength
- Number of elements in each block (nonnegative integer).
- stride
- Number of
bytes between start of each block (integer).
- oldtype
- Old data type (handle).
- newtype
- New data type (handle).
- IERROR
- Fortran only: Error
status (integer).
MPI_Type_create_hvector creates a vector (strided)
data type with offset in bytes.
NOTE - This routine replaces MPI_Type_hvector,
which is deprecated. See the man page MPI_Type_hvector(3) for information
about that routine.
The MPI standard prescribes portable
Fortran syntax for the STRIDE argument only for Fortran 90. FORTRAN 77
users may use the non-portable syntax
INTEGER*MPI_ADDRESS_KIND STRIDE
where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length
of the declared integer in bytes.
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.
