Customized Grid Resource Discovery using Globus Toolkit

Abstract

Grid computing involves heterogeneous resources of an organization working in collaboration to solve the problems that cannot be addressed by a single resource. Opportunistic sharing of Internet-connected resources is a low cost method for obtaining access to unprecedented-scale collections of resources. However, basic problem for Grid users is how to discover the best resources required for the particular type of a job. Grid Resource Discovery deals with identifying the resources, which are suitable for a particular kind of a job, by providing description of the resources that are visible to the Grid users. There are various approaches using which Grid Discovery can be performed. Web service based resource Discovery provided by Globus Toolkit is a well adopted standard in today’s Grid environment. Globus Toolkit’s Monitoring and Discovery System collects the resource information using inbuilt services and displays it using WebMDS. In this thesis, we extend the existing Resource Discovery techniques provided within Globus Toolkit which will enable us to customize the resource information according to the requirements based on the jobs to be run on the Grid and present it in our own format. Here we propose building up our own service on top of Globus MDS in order to process the information provided by MDS, customize it according to the requirement and display it using HTML page.
