MPI_Get function

Gets data from a memory window on a remote process.

Syntax

int MPIAPI MPI_Get(
  _Out_ void         *origin_addr,
        int          origin_count,
        MPI_Datatype origin_datatype,
        int          target_rank,
        MPI_Aint     target_disp,
        int          target_count,
        MPI_Datatype datatype,
        MPI_Win      win
);

Parameters

• origin_addr [out]
  Address of the buffer in which to receive the data.

• 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 window start to the beginning of the target buffer.

• target_count
  Number of entries in target buffer.

• 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.
