<p>The multi-resolution nature of the hierarchical space division, with its associated tree, in the fast multipole method, FMM. The diagram shows a three-level hierarchical decomposition of a 2D domain.  Tree nodes corresponding to domain boxes are shown in corresponding color.</p> <p>This figure appeared in the following paper, under (c) 2011 The Authors.</p> <p>“A tuned and scalable fast multipole method as a preeminent algorithm for exascale systems”, Rio Yokota, L A Barba.
