SCI: NMI DEVELOPMENT: Scalable Distributed Information Management System

该提案描述了一种基于dht的方法来构建一个可扩展的分布式信息管理系统，该系统可以聚合大规模网络系统的信息。通过监视、查询和响应分布式系统状态的变化，这样的系统被设想为大规模分布式应用程序的关键推动者。将与TACC合作开发原型并进行实验，预计在近期内通过可用技术增强网格基础设施，以改进数据复制、网格信息系统和分布式网络监控。该提案解决了聚合树抽象与内部DHT结构紧密集成所带来的新的可伸缩性、灵活性、自主性和健壮性问题。通过提供相当于分布式系统控制背板的功能，中间件基础设施应该得到极大的增强，并简化分布式应用程序的开发和使用。

The proposal describes a DHT-based approach to constructing a scalable and distributed information management system that aggregates information about large scale networked systems. Such a system is envisioned to be a key enabler of large-scale distributed applications through monitoring, querying and reacting to changes in the state of the distributed system(s). A prototype will be developed and experiments in collaboration with TACC are expected to enhance grid infrastructure in the near-term with usable technology to improve data replication, grid information systems, and distributed network monitoring. The proposal addresses new scalability, flexibility, autonomy, and robustness concerns raised by the tight integration of the aggregation tree abstraction with the internal DHT structure. By providing the equivalent of a distributed systems control backplane, middleware infrastructure should be greatly enhanced and simplify distributed application development and use.
