Automatic Workflow Management System in Grid Web-Based OS Environment with Advanced Scheduling Module

摘要

In a Grid Computing environment, there are various important issues, including information security, resource management, workflow management, routing, fault tolerance, and so on. Among these issues, the workflow management has emerged as one of the most important issues in past few years. Therefore, the research team of NCHC developed a workflow management system. The workflow management system can incorporate the properties of autonomic computing and exhibit the ability to reconfigure itself to the changes in the Grid environment. And, it can discover, diagnose, react to the disruptions of workflow execution, and monitor Grid resources automatically. And we also developed a workflow widget in Grid WebOS. The Grid WebOS is a web site that combined the Web-based Operating System (WebOS) platform with the Grid Computing environment to offer users a friendlier Grid environment. Currently, it joins the Grid, WebOS, and automatic resource selection mechanism to build a virtual computer in distributed environment. This progress helps to lower the barrier for using Grid Computing Environment. The research team of NCHC develops the Grid WebOS.
