class mpi_array.update.UpdatesForRedistribute(dst_distrib, src_distrib, peer_rank_translator=None)[source]¶

Collection of update extents for re-distribution of array elements from one distribution to another.

Methods

`__init__`(dst_distrib, src_distrib[, ...])
`calc_intersection_split`(dst_extent, src_extent)	Calculates intersection between `dst_extent` and {src_extent}.
`check_updates`()	Runs consistency checks on the calculated updates, assumes that the `dst_distrib` and `src_distrib` distributed as a partitioning (no locale extent overlaps except for halo).
`create_pair_extent_update`(dst_extent, ...)	Factory method for creating `PairExtentUpdate` objects.
`get_cpy2_src_extents`(dst_inter_locale_rank)
`initialise`()
`initialise_cpy2_updates`()
`initialise_rget_updates`()
`initialise_updates`()
