MPI_Put function

Put data into a memory window on a remote process.

Syntax

int MPIAPI MPI_Put(
  _In_ void         *origin_addr,
       int          origin_count,
       MPI_Datatype origin_datatype,
       int          target_rank,
       MPI_Aint     target_disp,
       int          target_count,
       MPI_Datatype target_datatype,
       MPI_Win      win
);

Parameters

• origin_addr [in]
  Initial address of origin buffer.

• origin_count
  Number of entries in origin buffer.

• origin_datatype
  Datatype of each entry in origin buffer.

• target_rank
  Rank of target.

• target_disp
  Displacement from start of window to target buffer.

• target_count
  Number of entries in target buffer.

• target_datatype
  Datatype of each entry in target buffer.

• win
  Window object used for communication.

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.
