◆ draw_tree_sketch()

35_offline-load-balancing-split-modes.draw_tree_sketch	(	axis,
		title,
		owners,
		caption
	)

Draw a one-dimensional spacetree with three levels.

owners holds the owner per level, i.e. a list with 1, 3 and 9 entries.

◆ read_subdomains()

35_offline-load-balancing-split-modes.read_subdomains ( directory )

Subdomain of each fine grid cell, read from the first snapshot's patch files.

The patch files hold one file per tree, but neither the file names nor the order in which the trees write their files tell us the tree number. We only know that tree 0 is the one tree which holds the cells along the periodic boundary. The result therefore holds 0 for tree 0 and 1, 2, ... for the other trees, numbered by the position of their first cell along the space-filling curve. These numbers are not necessarily Peano's tree numbers, as Peano runs through the curve forth and back in alternating mesh sweeps.
