- A Group Selection Pattern applied to Grid Resource Management ,Abstract: A key challenge in Grid computing is the achievement of efficient and self-organized resource management. Grids are often large scale, heterogeneous, and unpredictable systems. Introducing group structures can help to distribute coordination efforts, but higher levels of adaptation and learning in the coordination protocols are still required in order to cope with system complexity. We provide a solution based on a self-organized and emergent mechanism evolving congregations of resource management agents through a Group Selection process which maximizes utility outcomes for system-wide performance. We provide a formalization of the Group Selection pattern, and we propose several instantiations optimizing Grid resource management scenarios such as adaptive
job scheduling, market-based resource management and VO policy coordination. We further evaluate by simulation the performance of the mechanism in those scenarios.
- Social Networking to support Collaboration in Computational Grids ,Abstract: Grids are complex systems that aggregate large amounts of distributed computational resources to perform large scale simulations and analysis by multiple research groups. In this paper we unveil its social networks: actors that participate in a Grid and relationships among those Grid actors. Social networking information can be used as a means to increase awareness and to facilitate collaboration among Grid participants. In practice we have implemented a social networking tool so that Grid actors can discover partners to collaborate, potential providers and consumers, and their referrals path. We present and discuss the evaluation of such tool in a user study performed with Grid resource consumers and providers.
