Abstract

We describe a new parallel implementation of the octal-hierarchical tree N-body algorithm on SHared Memory systems (SHM) we have recently developed. Pursuing an effort to optimize as much as possible the code on a generic SHM we have modified the original algorithm introduced by Barnes and Hut, introducing a new scheme of "grouping" of particle interactions. We present speedup and efficiency results. . . .
