网格工作流调度研究综述

A SURVEY ON GRID WORKFLOW SCHEDULING

阐述了工作流调度的基本概念和调度的相关知识,分析了目前流行的网格工作流的调度算法的优缺点,并对当前的网格系统和项目所采用的调度机制,从不同侧面对其进行了比较分析。随着服务网格的日益流行,提出了面向服务网格环境下的服务工作流调度,分析了调度中的关键问题,并给出了解决问题的方法和思路。

In this paper it expatiates on the fundamental concept of grid workflow scheduling and its related knowledge. Then it analyzes current scheduling algorithms and gives their merits and demerits. It also analyzes the grid scheduling mechanisms which are adopted by grid projects and systems in various aspects. With the increasing popularization of the service grid, it presents the grid service workflow scheduling in orientation of the service grid environment, and analyzes the key issues of that scheduling. It also gives out the methods and ideas of problems solving.
