A Note on N-Body Computations with Cutoffs

Research output: Contribution to journalArticle

Abstract

We provide a theoretical analysis of the communication requirements of parallel algorithms for molecular dynamic simulations. We describe two commonly used algorithms, space decomposition and force decomposition, and analyze their communication requirements; each is better in a distinct computation regime. We next introduce a new hybrid algorithm that further reduces communication. We show that the new algorithm is optimal, by providing a matching lower bound.
