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.
