该项目将设计和构建一个大规模可扩展的基础设施，用于在广泛分布的资源集上执行网格应用程序。这样的基础设施将是分散的、强大的、高度可用的和安全的，同时有效地将应用程序映射到整个系统中的可用资源。这项建议以完全分散和分散的方式处理就业安置这一关键问题。提出的方法包括用于提交作业并将它们有效地匹配到可用资源的分布式算法，以及用于负载平衡和恢复的P2P技术；初步分析表明，所提出的方案规模与系统规模是无缝的，并且对组件故障和节点离开/加入具有较强的健壮性。该项目将实施并验证使用计算天文学中的一组问题开发的系统。这里提出的工作将使来自广泛科学学科的用户可以获得强大、可靠、大规模的计算资源，使用户能够形成特别的资源共享社区。这样的系统将使科学家能够无缝地向社区贡献资源，并在需要时利用这些资源。作为这项提议的一部分而开发的所有软件都将公之于众，并将帮助其他研究人员以及从业人员更好地评估所生产的软件并在此基础上进行改进。

The project will design and build a massively scalable infrastructure for executing grid applications on a widely distributed set of resources. Such infrastructure will be decentralized, robust, highly available, and secure, while efficiently mapping applications to available resources throughout the system. This proposal addresses the crucial problem of job placement in a completely distributed and decentralized manner. The proposed methods include a distributed algorithm for submitting jobs and efficiently matching them to available resources, and P2P techniques for both load-balance and for resilience; preliminary analysis indicated the proposed scheme scale is seamlessly with system size, and is robust against component failures and peer departures/joins. The project will implement, and validate the system developed using a set of problems in computational astronomy. The work proposed here will make robust, reliable, large-scale computing resources available to users from a broad range of scientific disciplines, allowing users to form ad-hoc resource-sharing communities. Such a system will enable scientists to seamlessly contribute resources to the community and to utilize these resources as needed. All the software developed as part of this proposal will be made publicly available and will help other researchers as well as practitioners to better evaluate the software produced and to build on it.
