MPI_Type_create_hvector function
Defines a new data type that consists of a specified number of blocks. Each block is a concatenation of the same number of elements of an existing data type. This function is similar to the function MPI_Type_vector except that the stride is specified in bytes instead of the number of elements.
Syntax
int MPIAPI MPI_Type_create_hvector(
int count,
int blocklength,
MPI_Aint stride,
MPI_Datatype oldtype,
_Out_ MPI_Datatype *newtype
);
Parameters
count
The number of blocks in the new data type.blocklength
The number of elements in each block.stride
The number of bytes between the start of one block and the next. The stride is a multiple of the extent of the old data type.oldtype
The MPI data type of each element.newtype [out]
On return, contains an MPI_Datatype handle that represents the new data type.
Return value
Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.
In Fortran, the return value is stored in the IERROR parameter.
Fortran
MPI_TYPE_CREATE_HVECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE, NEWTYPE, IERROR)
INTEGER COUNT, BLOCKLENGTH, STRIDE, OLDTYPE, NEWTYPE, IERROR
Remarks
This function replaces the MPI_Type_hvector function, which is deprecated.
