MPI_Scan function
Computes the scan (partial reductions) of data on a collection of processes.
Syntax
int MPIAPI MPI_Scan(
_In_ void *sendbuf,
_Out_ void *recvbuf,
int count,
MPI_Datatype datatype,
MPI_Op op,
MPI_Comm comm
);
Parameters
sendbuf [in]
Starting address of send buffer.recvbuf [out]
Starting address of receive buffer.count
Number of elements in input buffer.datatype
Datatype of elements of input buffer.op
Operation.comm
Communicator.
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.
