NAME
MPI_Type_create_hvector - Creates a vector (strided) data type with offset in bytes.SYNTAX
C Syntax
#include <mpi.h> int MPI_Type_create_hvector(int count, int blocklength, MPI_Aint stride, MPI_Datatype oldtype, MPI_Datatype *newtype)
Fortran Syntax (see FORTRAN 77 NOTES)
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
C++ Syntax
#include <mpi.h> MPI::Datatype MPI::Datatype::Create_hvector(int count, int blocklength, MPI::Aint stride) const
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).
OUTPUT PARAMETERS
- newtype
- New data type (handle).
- IERROR
- Fortran only: Error status (integer).
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(3) for information about that routine.
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 syntaxINTEGER*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.
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.
