Scientific Merit The principal investigators (PIs) will create a computing system that tightly couples extremely large-scale online disk storage with high-performance computing. This infrastructure will be shared among several research projects, each of which has a temporary need for large amounts of online storage when processing raw data, but has reduced storage requirements when operating on processed data. Computer Graphics: The PIs will perform precise measurement of the light scattering properties of objects. This will be the most accurate study of this kind ever undertaken, and will lead to a new generation of multidimensional, multi-object graphical rendering techniques. The World Wide Web: The PIs will perform studies measuring and quantifying the evolution of the World Wide Web. Until now, the sheer scale of the Web constrained reported studies of the Web to be performed exactly once. The new large-scale storage facility will enable the PIs to analyze multiple independent snapshots of the Web, to develop precise models for how the Web evolves over time. Astronomy: The PIs will store and analyze data from the newly upgraded Arecibo radio telescope, leading to discovery of new pulsars, including pulsars with millisecond spin periods and those in binary orbits with other neutron stars or black holes. The pulsar data will provide opportunities for research on the equation of state of nuclear matter, gravitation physics, gravitational waves, stellar evolution, relativistic plasma physics, and the magnetized, ionized gas in the Milky Way. The storage system will be hosted at the Cornell Theory Center. Analyzed data products from all projects will be made available over the Internet. Raw data will be shared with researchers throughout the U.S., either through visits to the Cornell Theory Center or by shipping data sets on disk drives.Broader Impact. The PIs have concrete plans for coupling the research with educational activities at all levels, as well as for general public outreach. The CURIE Academy: The PIs will develop novel projects for the Cornell CURIE Academy, a one-week summer engineering immersion experience for high school girls. The first CURIE project will use data obtained with the facility to illustrate fundamental principles of optics and computer graphics.Undergraduate Education: The work will impact undergraduate education in three different ways: (1) Several undergraduate courses are being adapted to make use of Web and astronomical data that will be available through the facility; (2) Cornell undergraduates will be invited to participate in supervised research related to the facility; and (3) The PIs will increase their interaction with Smith College, an undergraduate women's college in Massachusetts.Graduate Education: The facility will naturally provide opportunities for Ph.D. level research. In addition, several graduate courses are planning to address both the research being done on the facility and the general area of data-intensive computing. Public Outreach: The PIs research will be displayed in SciCentr, a virtual science museum run by the Cornell Theory Center accessible on the Web at www.SciCentr.org. SciCentr received museum accreditation through the Association of Science and Technology Centers (ASTC) in May 2004. The PIs will develop a SciCentr exhibition for each research project associated with the new facility.

主要研究人员（pi）将创建一个将超大规模在线磁盘存储与高性能计算紧密耦合的计算系统。该基础设施将在几个研究项目之间共享，每个研究项目在处理原始数据时都暂时需要大量在线存储，但在处理处理过的数据时减少了存储需求。计算机图形学：pi将对物体的光散射特性进行精确测量。这将是此类研究中最准确的，并将导致新一代多维、多对象图形渲染技术的出现。万维网：pi将进行研究，测量和量化万维网的发展。到目前为止，Web的绝对规模限制了对Web的报告研究只能进行一次。新的大规模存储设施将使pi能够分析Web的多个独立快照，以开发Web如何随时间演变的精确模型。天文学：pi将存储和分析新升级的阿雷西博射电望远镜的数据，从而发现新的脉冲星，包括具有毫秒旋转周期的脉冲星和与其他中子星或黑洞在双星轨道上的脉冲星。脉冲星数据将为研究核物质状态方程、引力物理、引力波、恒星演化、相对论等离子体物理以及银河系中的磁化电离气体提供机会。该存储系统将托管在康奈尔理论中心。所有项目的分析数据产品都将在互联网上提供。原始数据将与美国各地的研究人员共享，或者通过访问康奈尔理论中心，或者通过发送磁盘驱动器上的数据集。更广泛的影响。这些项目有具体的计划，将研究与各级教育活动结合起来，并进行一般的公众宣传。居里学院：这些pi将为康奈尔大学居里学院（Cornell CURIE Academy）开发新颖的项目，这是一个为期一周的暑期工程浸入式体验项目，面向高中女生。CURIE的第一个项目将使用该设备获得的数据来说明光学和计算机图形学的基本原理。本科教育：这项工作将以三种不同的方式影响本科教育：(1)一些本科课程正在调整，以利用将通过该设施获得的网络和天文数据；(2)康奈尔大学本科生将被邀请参加与该设施相关的指导研究；(3) pi将增加与马萨诸塞州的本科女子学院史密斯学院（Smith College）的互动。研究生教育：该设施自然会为博士水平的研究提供机会。此外，若干研究生课程正计划讨论正在进行的关于该设施的研究和数据密集计算的一般领域。公众宣传：pi的研究将在由康奈尔理论中心运营的虚拟科学博物馆scicentrr中展示，该博物馆可在www.SciCentr.org上访问。2004年5月，科学中心获得了中国科学技术中心协会（ASTC）的博物馆认证。pi将为与新设施相关的每个研究项目开发一个科学中心展览。
