Abstract

In Java computing context, ADAJ (Adaptive Distributed Application in Java) provides a both execution and programming system for irregular distributed applications. From the execution point of view, load balancing is an important issue and requires special information policies. Traditionally only the computer load is taken into account. Consequently, the load balancing is made by being unaware of the relations between objects. The objects are moved of a computer on the other without knowing the consequences in term of communication. To avoid that problem we introduce in that paper two mechanims: a relation observation mechanism of distributed objects and a computer load observation. The dynamical observation information provided by these mechanisms will be able to allow a general load balancing mechanism to have an intelligent adaptative object redistribution strategy. The proposed observation tools are entirely designed in Java. Some experiment results which concerns relation observations and overhead measurements are presented.

面向Java自适应分布式应用平台的对象观察

在Java计算环境中，ADAJ (Adaptive Distributed Application In Java)为不规则的分布式应用程序提供了一个执行和编程系统。从执行的角度来看，负载平衡是一个重要的问题，需要特殊的信息策略。传统上只考虑计算机负载。因此，负载平衡是通过不知道对象之间的关系来实现的。物体在另一台计算机上移动，而不知道通信方面的后果。为了避免这一问题，本文引入了分布式对象的关系观察机制和计算机负载观察机制。这些机制提供的动态观测信息将允许通用负载平衡机制具有智能自适应对象重新分配策略。建议的观察工具完全是用Java设计的。给出了一些关系观测和架空测量的实验结果。
