摘要
基于WFMC的工作流参考模型提出了网格工作流体系结构,扩展了基于遗传算法技术的规划算法以支持网格工作流自动建模,给出了基于市场驱动策略的动态调度算法以提高网格应用的服务质量,并介绍了在Globus上实现的原型系统JLGridFlow和其在大文件下载中的应用。
A grid workflow architecture based on WFMC workflow reference model was presented. An extended planning algorithm based on the genetic algorithm techniques was proposed to support the automatic generation of process description. A dynamic scheduling approach based on the market driven strategy was provided to improve the qualities of service (QoS) of grid applications. Finally, a prototype system JLGridFlow implemented on the Globus and the experiment of downloading big file were introduced.
