Advancements in technology over the past decade are leading to a promising future for large-scale distributed systems (LSDS), where globally-scattered distributed resources will be collectively pooled and used in a cooperative manner to achieve unprecedented petascale supercomputing capabilities. Ubiquitous users without preexisting trust relationships have posed a challenge of cooperative resource sharing. These facts necessitate that the issues of resource management (resMgt) and trust management (trustMgt) be addressed in order to ensure the successful deployment of LSDS. However, these two issues are typically addressed separately, despite the significant interdependencies between them: resMgt needs trustMgt to provide a cooperative environment for resource sharing, and in turn facilitates trustMgt to evaluate node multi-faceted trustworthiness in providing various resources. This proposal is aimed at integrating resMgt and trustMgt through the development of a distributed software architecture. The proposed project is built on two key innovations. (1) Lightweight multi-resource management. Unlike most previous multi-resource management approaches that depend on multiple infrastructures and incurring high overhead, or one infrastructure but causing bottlenecks, the project involves a single hierarchically integrated infrastructure without bottlenecks. (2) Integrated multi-faceted trust management. Unlike most previous trustMgt approaches that may not provide correct guidance for resource selection by assigning a node a single trust value for providing all resources, the project offers multi-faceted trust evaluation across multiple resources. Furthermore, it facilitates interaction between trustMgt and resMgt.

过去十年的技术进步为大规模分布式系统(LSD)带来了光明的未来，在LSD中，分散在全球各地的分布式资源将集中在一起，以一种协作的方式使用，以实现前所未有的千万亿级超级计算能力。没有预先存在信任关系的无处不在的用户对协作资源共享提出了挑战。这些事实要求必须解决资源管理(ResMgt)和信任管理(TrustMgt)问题，以确保成功部署LSD。然而，这两个问题通常是分开解决的，尽管它们之间存在显著的相互依赖关系：resMgt需要trustMgt为资源共享提供一个协作环境，反过来又有助于trustMgt评估节点在提供各种资源时的多方位可信度。该提议旨在通过开发分布式软件体系结构来集成resMgt和trustMgt。拟议中的项目建立在两项关键创新之上。(一)轻量化多资源管理。与大多数以前的多资源管理方法不同，多资源管理方法依赖于多个基础设施并招致高开销，或者一个基础设施但会造成瓶颈，该项目涉及一个没有瓶颈的单一层次集成基础设施。(2)多方位的一体化信任管理。与大多数以前的trustMgt方法不同的是，通过为节点分配用于提供所有资源的单个信任值，该项目提供了跨多个资源的多方面信任评估，从而可能无法为资源选择提供正确的指导。此外，它还促进了trustMgt和resMgt之间的交互。
