基于ACE技术开发的分布式计算任务管理器组件

An ACE-Based Distribution Computing Design of Task Manager Module

当分布式系统的计算结点数目增加到成百甚至上千时,使用派生进程或线程的方法处理I/O事件,会产生明显的通讯延时,大大降低系统的性能.针对这一问题提出了基于ACE技术的分布式计算任务管理器组件TaskBroker的模型和实现方法.Task Broker采用ACE提供的应用接口,实现了以异步方式使用一个或多个线程并发处理多个客户端请求的功能.实验证明,含有Task Broker的分布式并行计算系统能大大降低系统并行处理多个事件时的通讯延时,提高了系统性能.

The demands of grid computing system are increasing rapidly, causing the problem of considerable communication delay and reducing the system performance. Task Broker is a high-performance task manager component, it can resolve the problems mentioned above. This paper introduces the basic architecture of distributed parallel computing system based on task broker. It also expatiate particularly the parts of task broker＇s capabilities and how to achieve. At last the performance of task broker architecture is evaluated.
