17.2.385. MPI_Type_create_hvector
MPI_Type_create_hvector - Creates a vector (strided) data type with offset in bytes.
17.2.385.1. SYNTAX
17.2.385.1.1. C Syntax
#include <mpi.h>
int MPI_Type_create_hvector(int count, int blocklength,
MPI_Aint stride, MPI_Datatype oldtype, MPI_Datatype *newtype)
17.2.385.1.2. Fortran Syntax (see FORTRAN 77 NOTES)
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
17.2.385.1.3. Fortran 2008 Syntax
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
17.2.385.2. INPUT PARAMETERS
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).
17.2.385.3. OUTPUT PARAMETERS
newtype
: New data type (handle).IERROR
: Fortran only: Error status (integer).
17.2.385.4. DESCRIPTION
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 for information about that routine.
17.2.385.5. FORTRAN 77 NOTES
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.
17.2.385.6. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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.
