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

Defines a new data type that is a concatenation of a number of elements of an existing data type.

Syntax

int MPIAPI MPI_Type_contiguous(
        int          count,
        MPI_Datatype oldtype,
  _Out_ MPI_Datatype *newtype
);

Parameters

• count
  The number of elements in the new 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_CONTIGUOUS(COUNT, OLDTYPE, NEWTYPE, IERROR)
        INTEGER COUNT, OLDTYPE, NEWTYPE, IERROR

Remarks

The concatenation of the new data type is defined by using the extent of the old data type as the size of the concatenated copies.
