Molecular dynamics simulations (MDS), no matter in which form, have always spent a lot of effort on the time-consuming part of direct particle-to-particle interactions (O(N 2 )). Even if the interaction radius of each particle is limited, it remains

Portable Node-Level Performance Optimization for the Fast Multipole Method

Autor: Andreas Beckmann, Ivo Kabadshow

Publikováno v: Lecture Notes in Computational Science and Engineering ISBN: 9783319229966

This article provides an in-depth analysis and high-level C++ optimization strategies for the most time-consuming kernels of a Fast Multipole Method (FMM). The two main kernels of a Coulomb FMM are formulated to support different hardware features, s
