MPI_Type_vector function - Message Passing Interface (original) (raw)

Defines a new data type that consists of a specified number of blocks of a specified size. Each block is a concatenation of the same number of elements of an existing data type.

Syntax

int MPIAPI MPI_Type_vector(
        int          count,
        int          blocklength,
        int          stride,
        MPI_Datatype oldtype,
  _Out_ MPI_Datatype *newtype
);

Parameters

count
The number of blocks in the created vector.
blocklength
The number of elements in each block.
stride
The number of elements between the start of one block and the start of the next block.
oldtype
The 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_VECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE, NEWTYPE, IERROR)
        INTEGER COUNT, BLOCKLENGTH, STRIDE, OLDTYPE, NEWTYPE, IERROR
