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
- 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 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.
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.
