SubtileGridSizer

Bases: GridSizer

dim_extents property

__init__(nx, ny, nz, n_halo, data_dimensions, backend)

from_tile_params(nx_tile, ny_tile, nz, n_halo, layout, *, backend, data_dimensions=None, tile_partitioner=None, tile_rank=0) classmethod

Create a SubtileGridSizer from parameters about the full tile.

Parameters:

Name	Type	Description	Default
nx_tile	int	number of x cell centers on the tile	required
ny_tile	int	number of y cell centers on the tile	required
nz	int	number of vertical levels	required
n_halo	int	number of halo points	required
layout	tuple[int, int]	(y, x) number of ranks along tile edges	required
backend	Backend	current backend in use	required
data_dimensions	dict[str, int] | None	lengths of any non-x/y/z dimensions, such as land or radiation dimensions	None
tile_partitioner	optional	partitioner object for the tile. By default, a TilePartitioner is created with the given layout	None
tile_rank	optional	rank of this subtile	0

from_namelist(namelist, tile_partitioner=None, tile_rank=0, *, backend) classmethod

Create a SubtileGridSizer from a Fortran namelist.

Parameters:

Name	Type	Description	Default
namelist	dict	A namelist for the fv3gfs fortran model	required
tile_partitioner	optional	a partitioner to use for segmenting the tile. By default, a TilePartitioner is used	None
tile_rank	optional	current rank on tile. Default is 0. Only matters if different ranks have different domain shapes. If tile_partitioner is a TilePartitioner, this argument does not matter	0
backend	Backend	current backend in use	required
