ITR: ASE: INT: DMC: UltraLight: An Ultrascale Information System for Data Intensive Research

这份ITR提案是为开发和部署UltraLight提供资金的请求，UltraLight是新型集成信息系统中的第一个，将支持大型强子对撞机（LHC）和其他下一代科学领域长达数十年的研究项目。大型强子对撞机的物理学家面临着前所未有的挑战：(1)到2010年，大规模的、全球分布的数据集将增长到100拍字节的水平；(2)千万亿次的分布式计算；(3)由数千名科学家组成的全球社区的协作数据分析。为了应对这些挑战，LHC合作开发的基于网格的基础设施提供了大量的计算和存储资源，但由于它们将网络视为外部的、被动的、基本上不受管理的资源而受到限制。UltraLight将通过一套分布式的智能全球服务，实时监控、管理和优化网络的使用，从而克服这些限制。UltraLight混合分组和电路交换网络基础设施将采用超大规模协议和动态光路构建，在高达10gbps范围的远程网络上提供有效的公平共享。UltraLight的范围为学生提供了令人兴奋和不同寻常的教育推广机会。它为E&amp；O活动提供直接和重要的支持，包括：应用程序开发、实验参与、基础设施部署和参与机构的实习。GriPhyN、iVDGL和e-VLBI网格项目中的现有推广计划，以及佛罗里达国际大学的CHEPREO和CIARA计划，将被用来吸引本科生学习物理和数学，并为核心研究生科学领域注入新的重要信息技术元素。

This ITR proposal is a request for funding to develop and deploy UltraLight, the first of a new class of integrated information systems that will support the decades-long research program at the Large Hadron Collider (LHC) and other next generation sciences. Physicists at the LHC face unprecedented challenges: (1) massive, globally distributed datasets growing to the 100 petabyte level by 2010; (2) petaflops of distributed computing; and (3) collaborative data analysis by global communities of thousands of scientists. In response to these challenges, the Grid-based infrastructures developed by the LHC collaborations provide massive computing and storage resources, but are limited by their treatment of the network as an external, passive, and largely unmanaged resource. UltraLight will overcome these limitations by monitoring, managing and optimizing the use of the network in realtime, using a distributed set of intelligent global services. The UltraLight hybrid packet- and circuit-switched network infrastructure will employ ultrascale protocols and dynamic building of optical paths to provide efficient fair-sharing on long range networks up to the 10 Gbps range. UltraLight's scope offers exciting and unusual educational outreach opportunities for students. It provides direct and significant support for E&O activities including: application development, experiment participation, infrastructure deployment, and internships at participating institutions. Existing outreach programs within the GriPhyN, iVDGL, and e-VLBI Grid projects, as well as Florida International University's CHEPREO and CIARA programs, will be exploited to attract undergraduates to physics and math, and to inject new important elements of information technology into core graduate science domains.
