Model-driven grid portal configuration system and method

Abstract

The invention relates to model-driven grid portal configuration system and method. The system comprises a plug-in object, a host frame, a WEB application server and a browser, wherein the plug-in object comprises a plurality of grid services; the display modes of all the grid services are described by an appearance definition file; the attributes, the form information and the running logics of all the grid services are described by an XML (Extensive Makeup Language) file; the execution process of all the grid services are described by a script file; the appearance definition file, the XML file and the script file form a grid service model; and the host frame can call the plug-in object, the plug-in object can realize a service logic thereof on the host frame, and the host frame and the plug-in object communicate on the basis of a common communication contract. A plug-in and the host frame are connected during running, not compiling. The method can effectively reduce a coupling degree between a functional object provided by a portal and an object management logic, can be reused, has flexibility and can ensure the optimal configuration of the grid portal system.

Description

technical field [0001] The invention relates to a grid portal configuration method, which belongs to the technical field of computer networks. Background technique [0002] Grid is an emerging technology built on the Internet. The virtual test grid integrates various heterogeneous resources distributed in the test environment (including computing resources, storage resources, data resources, information resources, equipment resources, etc.) Organizations share resources and work together, and provide users with consistent interfaces and services for virtual experiments that require high-performance computing capabilities. Grid resources and services in grid applications are usually presented to end users in the form of API interfaces or command line interfaces, which require users to have a clear understanding and configuration of complex grid environments, which will make it difficult for non-professional users to master How to use the grid system. Therefore, grid portal...

AI Technical Summary

Problems solved by technology

The transaction logic executes the function call in the portal, and the expression logic is responsible for converting the function execution result into an html page, and the portal cannot reflect the attributes, categories and call information of the grid service

Computer Engineering and Design, Volume 27, 2006, "Design and Implementation of Grid Portal Based on JSF" uses JSF technology to enrich the expressive ability of grid portal, but its model corresponds to the binding of WEB page tags, so it can only Grid service display can be configured, the grid service itself cannot be configured, and runtime compilation cannot be implemented
