Distributed particle simulation method on adaptive collaborative system

This paper presents a distributed N-body method based on an adaptive collaborative system model. The collaborative system is built with the distributed objects in a cluster. It can be reconfigured during the computation to fully utilize the computing power of the cluster. The method is implemented in Java and RMI to support distributed computing on heterogeneous platforms. A distributed tree structure is designed for communication-efficient computing of the method. The performance test shows good speedup and portability of the method on homogeneous and heterogeneous clusters. The collaborative system model is practical for various applications and is expandable to wide-area environment.
