Overview: Managing usage SLAs within large environments that integrate participants and resources spanning multiple physical institutions is a challenging problem. Maintaining a single unified usage SLA management decision point over hundreds to thousands of jobs and sites can quickly become a problem in terms of reliability as well as performance. Previous work developed GRUBER, a distributed grid Usage SLA-based resource broker that allows multiple decision points to coexist and cooperate in real-time. GRUBER ultimately addresses issues regarding how usage SLAs can be stored, retrieved and disseminated efficiently in a large distributed environment. The key question this paper addresses is the scalability and performance of GRUBER in large Grid environments.
