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（LSDS）带来了光明的未来，全球分散的分布式资源将被集中起来，并以合作的方式使用，以实现前所未有的千万亿次超级计算能力。无处不在的用户没有预先存在的信任关系，提出了一个合作资源共享的挑战。这些事实需要解决资源管理（resMgt）和信任管理（trustMgt）的问题，以确保LSDS的成功部署。然而，这两个问题通常分别解决，尽管它们之间的显着的相互依赖性：resMgt需要trustMgt提供一个合作的环境资源共享，并反过来促进trustMgt评估节点多方面的可信度提供各种资源。该建议的目的是通过开发分布式软件架构来集成resMgt和trustMgt。该项目基于两项关键创新。(1)轻量级多资源管理。与大多数以前的多资源管理方法不同，这些方法依赖于多个基础设施并产生高开销，或者一个基础设施但导致瓶颈，该项目涉及一个没有瓶颈的分层集成基础设施。(2)综合多方面的信任管理。与大多数以前的trustMgt方法不同，这些方法可能无法通过为节点分配单个信任值来提供所有资源，从而为资源选择提供正确的指导，该项目提供了跨多个资源的多方面信任评估。此外，它促进了trustMgt和resMgt之间的交互。
