基于移动代理网格计算中任务调度的研究

Research of Grid Computing Task Scheduling Based on Mobile Agent

目的是结合虚拟组织思想,给出在移动代理环境下的网格任务调度的模型。首先,阐述了网格环境下任务调度的六个主要方面,包括任务分解、资源发现与选取、任务分配、任务运行、任务监视与恢复、任务协调与集成。接着,给出了以移动代理技术为实现手段的、虚拟组织为网格基本管理单位的网格任务调度的体系结构,并对该体系结构进行了描述。

The purpose of the thesis is to provide a model of grid task scheduling based on mobile agent environment combined with thought of virtual organization. First, the thesis sets forth six main aspects of task scheduling in grid environment, including task decomposition, resource discovery and selection, task distribution, task running, task monitoring and recovery, task coordination and integration. Next, the thesis advances the architecture of grid task scheduling which resorts to mobile agent technology and views virtual organization as the basic management unit of the grid. Moreover, the architecture is described in the thesis.
