This project explores employing distributed computational resources to combat the unreliability and highly variable performance inherent to wide-area systems. The goal of this work is to balance wide-area performance, security, and resource utilization by efficiently replicating and migrating computation using inexact information distributed across multiple administrative domains. To this end, this research addresses three areas important to scaling the global network infrastructure: i) dynamic placement and migration of computation for efficient utilization of global resources, ii) resource allocation among principals simultaneously utilizing resources in multiple administrative domains, and iii) a security infrastructure that enables the fine-grained transfer of rights for wide-area computation. The impact of this work will be increase fairness, scalability, and fault tolerance for distributed systems leveraging this infrastructure.

该项目探索利用分布式计算资源来应对广域系统固有的不可靠性和高度可变的性能。 这项工作的目标是通过使用跨多个管理域分布的不精确信息有效地复制和迁移计算来平衡广域性能、安全性和资源利用率。 为此，本研究解决了扩展全球网络基础设施的三个重要领域：i）计算的动态放置和迁移，以有效利用全球资源，ii）同时利用多个管理域中的资源的主体之间的资源分配，以及iii）安全基础设施，可实现广域计算的细粒度权利转移。 这项工作的影响将是提高利用该基础设施的分布式系统的公平性、可扩展性和容错能力。
