An Ontology Based Resource Scheduling Scheme in Grids

Abstract

Traditional schedulers in the grid environment do not support semantic description of grid resources and jobs. They do exact matching between resource requesters and providers. These mechanisms are too restrictive because there is no prior agreement on how a resource or a service or a job will be represented. In this paper, we propose an extensible scheduler that uses the semantic description of entities related to scheduling. More precisely, the scheduler uses the semantic description of resources and jobs by means of ontology. Furthermore, it exploits a semantic matching scheme to perform scheduling. Experimental results show the feasibility and effectiveness of the proposed scheduler.
