## [6.11] Design and Performance of a Parallel Particle-Mesh Code as a Solution to the N-body Problem

*John F. Wallin (CSI/GMU), Imran Shah (CSI/GMU)*
Particle-mesh calculations have been used as one method to
solve the N-body problem in plasma and gravitational calculations.
Because of the fixed grid shapes in these calculations, they are
well suited for solutions using massively parallel computers.
During the last year, we have been developing a parallel particle-mesh
code to solve the gravitational N-body problem. The results from
the initial performance and stablity tests of this code are
presented along with the data and software structure used in its
implementation.
