Comparison of LOC run times on a GPU for different octree grids. The octree hierarchies have NL = 1 − 4 levels and a root grid of 643 (frame a) or 1283 (frame b) cells. The solid lines connect two cases where either 10% or 30% of the cells of the previous level are refined. The dotted lines indicate the slope of one-to-one scaling between the run time and the number of cells.
