\(N\)-body simulations of massively parallel architectures (Q1339959)

The simulations of the properties of \(N\) particles, mutually interacting through a pair-wise force, yield information that is inaccessible by other means and that leads to insight into predictable behavior for a wide range of problems. In this paper, the authors give several simple procedures that reduce by an order of magnitude the computation time of such simulations on the massively parallel machine CM-200. Two methods are used simultaneously: one is the ``all-to-all broadcast method'', another is the ``Fortran 90 method''.
