MpiPairExtentUpdate.
do_rget
(mpi_win, target_src_rank, origin_dst_buffer)[source]¶ Performs calls
mpi4py.MPI.Win.Rget()
method ofmpi_win
to perform the RMA data-transfer.Parameters: - mpi_win (
mpi4py.MPI.Win
) – Window used to retrieve update region for array. - target_src_rank (
int
) – The rank of the target process inmpi_win.group.rank
. - origin_dst_buffer (
memoryview
) – The destination memory for the update, size of buffer should correspond to the size of thedst_extent
.
