大规模松散耦合的PC机可以组织成集群，在共享各自处理能力的基础上形成网格计算; PC机的处理能力、代码迁移和事务分布是分布式系统性能的重要特征。本文描述了大规模松耦合分布式系统中目标代码迁移控制机制。实现了一个为计算迁移目标代码的中间件原型，并观察了代码迁移的权衡。在此基础上，对大规模松散耦合PC机群系统进行了仿真研究，提出了控制代码迁移以保证系统响应时间稳定的方法。根据仿真结果提出了目标代码迁移机制。研究结果将应用于设计网格计算系统和移动的系统，以保持适当的性能。
Large scale loosely coupled PCs can organize a cluster and form the grid computing on sharing each processing power; power of PCs, code migration and transaction distribution characterize the performance of distributed systems. This paper describes object code migration control mechanism in large scale loosely coupled distributed systems. The prototype of the middleware which migrates object code for computing is implemented, and the tradeoff of code migration was observed. Based on these experiments, several simulations for large scale loosely coupled PC clusters were performed, and the methodology to control code migration to have stable response time in the system is derived. The mechanism for object code migration is proposed based on the results of the simulations. The result will be applied to design the grid computing systems and mobile systems to maintain the proper performance.
