A Many-Core Implementation of the Direct N-Body Problem
Alejandro Duran*; Larry Meadows†* Intel Corporation, Spain† Intel Corporation, USA
This chapter presents several optimizations that are usually necessary to obtain good performance on an Intel Xeon Phi coprocessor. It also explains why these optimizations where done intending that the applicability of the chapter is broader than the N-body kernel that is used to drive the presentation. These optimizations also lead to the performance improvement on processors in general.
N-Body simulations are a common astrophysics problem that computes the movement of gravitationally ...
