A Note on N-Body Computation with Cutoffs

We provide a theoretical analysis of the communication
requirements of parallel algorithms for molecular dynamic simulations.
This paper contributes some improvements and a more precise analysis of
communication, for previously used algorithms.  It defines a new
algorithm with improved communication.  It analyzes it, both for a
machine with a complete graph topology and for a machine with a mesh
topology, and proves matching lower bounds on communication complexity.
