An Evaluation of Computing Paradigms for N-body Simulations on Distributed Memory Architectures
- In Proc. Seventh Symp. on Principles and Practice of Parallel Programming
, 1999
"... The eciency of HPF with respect to irregular applications is still largely unproven. While recent work has shown that a highly irregular hierarchical n-body force calculation method can be implemented in HPF, we have found that the implmentation contains ine- ciencies which cause it to run up to a f ..."

, file transfer rates, and processing performance. The evaluation includes a computational fluid dynamics code and an N-body gravitational simulation program. It is shown that the Beowulf architecture provides a new operating point in performance to cost for high performance workstations, especially
Experiences with parallel N-body simulation
, 2000
"... This paper describes our experiences developing high-performance code for astrophysical N-body simulations. Recent N-body methods are based on an adaptive tree structure. The tree must be built and maintained across physically distributed memory; moreover, the communication requirements are irregul ..."

Experiences With Fractiling In N-Body Simulations
- In Proceedings of High Performance Computing'98 Symposium
, 1998
"... N-body simulations pose load balancing problems mainly due to the irregularity of the distribution of particles and to the different processing requirements of particles in the interior and of those near the boundary of the computation space. In the past, most of the methods to overcome performance ..."
