enum.Enum
Generic enumeration.
Derive from this class to define new enumerations.

- tile_indirection_map()[source]
The tile indirection map. Its shape is (nb_tiles_y,nb_tiles_x,2). The z-axis contains the indirected coordinates of the bottom-left corner of the tile denoted by the x and y axis values. For example, if you have the tile coordinates (t_i, t_j), then map[t_i, t_j, :] is a 2-tuple containing the coordinates (in meshes) of the bottom-left corner of that tile, on the indirected map.
- mode() TilePackingMode [source]
- packed_size()[source]
Size of the arrays after padding them and packing them in tiles, expressed in meshes. Size is a (width, height) tuple.
Note that this size can be very different than the actual computation domain size.
- packed_size_in_tiles()[source]
Size of the arrays after padding them and packing them in tiles, expressed in tiles. Size is a (width, height) tuple.
Note that this size can be very different than the actual computation domain size.
- size_in_tiles()[source]
Size of the (original, non packed, non tiled) computation domain, in tiles. Not that we count full tiles. So if one dimension of the domain is not a multiple of the tile size, then we round one tile up.
Size is a (width, height) tuple.
- unpack_and_deshuffle_array(a: numpy.ndarray) numpy.ndarray [source]
De-shuffle and un-pad an array of tiles that was shuffled and padded.
- _pad_array_to_tiles(a: numpy.array, neutral_values) numpy.array [source]
Make an array fit in a given number of tiles (on x and y axis). After this, the array’s dimensions are multiple of the tile_size.
- Parameters:
neutral_values – The value used to pad.
- shuffle_and_pack_array(a: numpy.array, neutral_values=None, debug=False) numpy.array [source]
Reorganize an array by moving tiles around to follow the ordering given by self._tile_indirection_map The array is resized in order to be just as large as needed to hold the active tiles plus the “empty” tile.
neutral_values: value to fill the empty tile with.
