基于元组空间的网格工作流调度机制

Tuple space based grid workflow scheduling mechanism

为了满足网格工作流调度进程中交互活动的灵活性和多样性,提出了一个基于扩展元组空间的工作流调度机制。这种扩展的元组空间引入了交互通道的概念,增加了触发和过滤规则。论证及实例研究表明这种工作流调度机制在元组操作方面更具有针对性和安全性。使用该机制的体系结构和编程接口,将有利于在工作流的调度中平衡信息的开放性和保护性。

In order to meet the flexibility and multiplicity of the interactions in the process of grid workflow scheduling, a workflow scheduling mechanism based on extended tuple space was proposed. The extended tuple space introduced a concept of interaction channel and added the triggering and filtering rules. Demonstrations and study of the examples showed that this workflow scheduling mechanism made tuples operation more direct and secure. Employing the architecture and programming interface of the mechanism is beneficial to balance the openness and protection of information in the process of workflow scheduling.
