【摘要】 将调度系统与网格中其他组件有效整合、建立网格环境下任务调度体系结构、构建真实网格环境下的资源管理与任务调度系统具有重要的现实意义。本文提出了一个三层分布式网格任务调度体系结构模型,侧重解决网格固有的异构、站点自治与策略可扩展性,网格域调度器是分布式调度系统核心组件,详细阐述了网格域调度器的功能模块设计与任务调度步骤;最后,通过一个应用级网格任务调度实例,给出网格任务调度过程及效果。更多还原

【Abstract】 Task scheduling is one of the most challenging problems in the grid resource management.A three-level distributed task scheduling architecture is proposed,which puts emphasis on the heterogeneity,autonomy and scalability of the computational grid.The domain scheduler is the key module of the system and its behaviors are explained in detail.The usability and validity of the grid scheduling system are exhibited with the N-body grid application in a campus computational grid testbed.更多还原
