Towards a standards-based grid scheduling architecture

The definition of a generic Grid scheduling architecture is the concern of both the Open Grid Forum's Grid Scheduling Architecture Research Group and a CoreGRID research group of the same name. Such an architecture should provide a blueprint for Grid system and middleware designers and assist them in linking their scheduling requirements to diverse existing solutions and standards. Based on work executed within the Open Grid Forum related to scheduling use cases and requirements, which tackles the problem from a more theoretical point of view, we approach in this paper the problem practically by evaluating the teikoku Grid Scheduling Framework in the light of standards-compliance. The results of this evaluation and the existing Grid Scheduling Architecture proposal are set into context, existing gaps are described and potential solutions to bridge them are introduced. In doing so, we concentrate on the interoperability of schedulers and the necessity of a Scheduling Description Language to achieve it.
