Inheritance diagram for Let3d_MPI:
The LET is a global tree subset that a processor needs to evaluate the interaction on particles which belong to itself (owns). That is, it is a unique identifier: a set of points and its bounding box. To this extent, for a box/node B, the information from B's lists are needed. Specifically, the U, V, W and X lists are used for computation. More information is in the descriptiptions of _Unodes, etc. and the papers. For a processor P, P's LET contains the boxes which P "owns" and boxes in the U,V,W and X lists of these boxes. For a box, B, owned by P, P is a contributor of B. If B is in the U,V,W or X lists of a box P owns, P is a user of B. For more information, see "A New Parallel Kernel-Independent Fast Multipole Method" by Ying, Biros, Zorin and Langston.
