一种基于网格服务的分布式远程协同仿真系统研究

随着面向服务的体系结构(SOA)成为网格研究领域的基本共识,越来越多的应用领域开始涉足网格中来;其中分布式远程协同就是其中的代表. 从全新的视角对分布式协同的重要技术之一--工作流进行了分析,提出工作流网格资源化的概念;定义工作流模型资源为网格资源,并遵照网格资源描述的规范描述工作流模型资源,做到从网格基础设施资源层支持协同工作流. 同时以该工作流模型为原型,以面向服务的体系结构为基本框架,构建网格环境中协同工作流服务框架,从而实现基于工作流的面向服务的分布式远程协同仿真系统.

Research on grid-service-based distance-distributed-collaboration simulation system

As the SOA architecture becomes the basic support,more and more applications start to use grid.The typical sample is the distributed-collaboration application.The paper analyzes the workflow,which is one kind of key technology of distributed-collaboration application,from a new angle.The authors also put forward the concept of workflow grid resource and define the workflow model to be the grid resource as well as describe the workflow model resource according to the grid resource definition.Supporting workflow-collaboration from the grid base level and based on the prototype of workflow model and SOA architecture,the authors have built the distributed-collaboration architecture in the grid system and implemented the service-oriented and workflow-based distributed-collaboration simulation system.
