Abstract

We present a reformulation of the well-known GRAM architecture based on the Service-Level Agreement (SLA) negotiation protocols defined within the Service Negotiation and Access Protocol (SNAP) framework. We illustrate how a range of local, distributed, and workflow scheduling mechanisms can be viewed as part of a cohesive yet open system, in which new scheduling strategies and management policies can evolve without disrupting the infrastructure. This architecture remains neutral to, and in fact strives to mediate, the potentially conflicting resource, community, and user policies.
