AP3M: Adaptive Particle-particle, Particle-mesh Code

Abstract: AP<sup>3</sup>M is an adaptive particle-particle, particle-mesh code. It is older than <a href="">Hydra</a> (ascl:1103.010) but faster and more memory-efficient for dark-matter only calculations. The Adaptive P<sup>3</sup>M technique (AP<sup>3</sup>M) is built around the standard P<sup>3</sup>M algorithm. AP<sup>3</sup>M produces fully equivalent forces to P<sup>3</sup>M but represents a more efficient implementation of the force splitting idea of P<sup>3</sup>M. The AP<sup>3</sup>M program may be used in any of the three modes with an appropriate choice of input parameter.
