MPI_Type_create_darray function - Message Passing Interface (original) (raw)
Creates a datatype representing a distributed array.
Syntax
int MPIAPI MPI_Type_create_darray(
int size,
int rank,
int ndims,
_In_count_(ndims) int array_of_gszies[],
_In_count_(ndims) int array_of_distribs[],
_In_count_(ndims) int array_of_dargs[],
_In_count_(ndims) int array_of_psizes[],
int order,
MPI_Datatype oldtype,
_Out_ MPI_Datatype *newtype
);
Parameters
- size
Size of process group. - rank
Rank in process group. - ndims
Number of array dimensions as well as process grid dimensions. - array_of_gszies
Number of elements of type oldtype in each dimension of global array. - array_of_distribs
Distribution of array in each dimension. - array_of_dargs
Distribution argument in each dimension. - array_of_psizes
Size of process grid in each dimension. - order
Array storage order flag. - oldtype
Old datatype. - newtype [out]
New datatype.
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.
