ShapeSplitter.calculate_split_halos_from_extents()[source]¶

Returns (self.ndim, 2) shaped halo array elements indicating the halo for each split. Tiles on the boundary may have the halo trimmed to account for the tile_bounds_policy.

Return type:	`numpy.ndarray`
Returns:	A `numpy` structured array where each element is a `(self.ndim, 2)` shaped `numpy.ndarray` indicating the per-axis and per-direction number of halo elements for each tile in the split.
