Distributed particle simulation method on adaptive collaborative system

This paper presents a distributed N-body method based on an adaptive collab orative system model. The collaborative system is formed by the distributed objects on a distributed system. The system can be reconfigured during the computation to fully utilize the computing power of the networked hosts. T he method is implemented in Java and RMI to support distributed computing i n heterogeneous environment. A distributed tree structure is designed for c ommunication-efficient computation of N-body method. The performance test s hows satisfactory speedup and portability of the method on both homogeneous and heterogeneous clusters. The collaborative system model can be used in various applications and it is expandable to wide-area environment. (C) 200 1 Elsevier Science B.V. All rights reserved.
