Java并行计算环境中的负载监测系统

Load Inspecting System in Java Parallel Computing Environment

动态负载平衡是使用机群进行网络并行计算的关键,而获取节点的负载信息是实现动态负载平衡的前提。该文介绍了并行计算Java环境中负载监测系统的体系结构和使用中结合机制的实现方法,并讨论了使用的负载信息获取技术和原始数据的处理JSYSJavaRMIJNIJSYS方法,实验结果表明能够有效地为动态负载平衡提供服务。

Acquiring of load information is a precondition for dynamic load balancing which is a critical issue of networking parallel computing. In this paper, we present the architecture and implementation of JSYS (the load status inspecting system in Java parallel computing environment) which uses Java RMI&JNI. The techniques of how to get the load information and the data processing method are also discussed. The experiment results show that the JSYS works correctly and it can provide effective services for dynamic load balancing requirement.;
