Research On The Grid Service And Application Based On OGSA

As the various needs of people for information increase rapidly, grid computing develops promptly, which had been considered as the next tidal wave of IT development. Resource share and connectivity can be realized by using grid technology. Nowadays, Web technology and grid technology are the two research hotspot, the new grid architecture --OGSA has formed by combining newest Web service technology and grid technology together. OGSA is an oriented-service architecture, and grid service based on OGSA is a kind of special Web service which realize the share of information, resource and application by defining a set of interface that obey to special stipulation.Based on the research of OGSI specification which is OGSA architecture , grid service based on OGSA and globus toolkit architecture model, the paper analyzes the frame model of server and client of grid service in GT3 grid environments, Designs the grid service application frame based on OGSA which is based on SORE prototype system that has been established by our research team. This frame takes service as core, supports grid service standard, achieves the sharing of information and resource by deploying and invoking information service node.The paper researches GT3 architecture, analyzes the deploy process of Grid service, makes normalize design for the installation steps of GT3. Under 2000 Windows operating systems, develops and deploys a scientific computing Grid service instance successfully by using GT3.0 Core, accomplishes the service deploy on both server and client, invokes the service instance on the client. The paper Verify the realization of application frame core, that is to realize grid service dynamic deploy and registration with Globus Toolkit.Finally, The paper makes a conclusion of the work. Evaluate the shortage, and point out the future work based on the development of Grid service.
