A Middleware for legacy application wrapper

The past few years have witnessed an increasingly tight link between grid computing and Web services. But there is a large amount of legacy application which is not accessible as grid service in scientific computing domain. In this paper, we provided a new approach to deploy an existing scientific computing legacy application on grid without modifying the original code. It simplifies the task of wrapping legacy application as standard grid services. We provided abundant execution information about legacy application and defined a flexible mechanism to customize monitor plug-ins. It enables users to catch the domain related information of scientific computing legacy application in time.
