Similar to MPI_PUT, except that the direction of data transfer is reversed. Data are copied from the target memory to the origin. The origin_datatype may not specify overlapping entries in the origin buffer. The target buffer must be contained within the target window, and the copied data must fit, without truncation, in the origin buffer.
