Enabling Transformational Science and Engineering Through Integrated Collaborative Visualization and Data Analysis for the National User Community

该提案将使用2009年美国复苏和再投资法案（公法111-5）提供的资金，并符合2009年3月20日白宫备忘录第2节的要求，题为“确保负责任的复苏法案资金支出”。我还确认，作为认可的项目官员，该提案不支持《复苏法案》A部分第1604条所述的项目。通过集成协作可视化和数据分析为国家用户社区实现转型科学和工程可视化是分析和解释数字资产的最重要和最常用的方法之一。对于许多类型的计算研究来说，它是唯一可行的从数据中提取信息和发展理解的方法。然而，非可视化数据分析技术、统计分析、数据挖掘、数据约简等在知识发现的许多领域也发挥着不可或缺的作用。该合同将首次为开放科学界提供一套全面的大规模可视化和数据分析（VDA）服务。通过利用现有的工具和技术，整合最先进的研究产品，并提供卓越的用户支持，我们将部署一个全国性的、通用的可视化和数据分析发现环境。交付成果包括：1、一个具有超强能力的远程可视化资源（Longhorn）； 2、256个节点（2048个处理器核心，峰值24 Tflops）， 512个gpu， 12太字节的总内存，200太字节的本地系统存储，与Ranger （TeraGrid的首个Track2系统）紧密集成，以处理最大规模的数字资产（以及潜在的未来TACC HPC系统）；1. 全面的开源和商业终端用户VDA软件工具集合；2. 专家可视化支持，包括高级交互式用户支持和培训，由美国许多领先的可视化研究人员组成的团队；和3。一个框架，用于快速集成来自领先研究团队（包括我们自己的）的新可视化技术，以增加整个项目的用户能力。为全国用户社区精心设计的可视化和数据分析

This proposal will be awarded using funds made available by the American Recovery and Reinvestment Act of 2009 (Public Law 111-5), and meets the requirements established in Section 2 of the White House Memorandum entitled, Ensuring Responsible Spending of Recovery Act Funds, dated March 20, 2009. I also affirm, as the cognizant Program Officer, that the proposal does not support projects described in Section 1604 of Division A of the Recovery Act. Enabling Transformational Science and Engineering through Integrated Collaborative Visualization and Data Analysis for the National User CommunityVisualization is one of the most important and commonly used methods of analyzing and interpreting digital assets. For many types of computational research, it is the only viable means of extracting information and developing understanding from data. However, non-visual data analysis techniques, statistical analysis, data mining, data reduction, etc. also play integral roles in many areas of knowledge discovery. This award will, for the first time, provide a comprehensive suite of large-scale visualization and data analysis (VDA) services to the open science community. By leveraging existing tools and techniques, integrating state-of-the-art research products, and providing exceptional user support, we will deploy a national, general-purpose visualization and data analysis discovery environment. The deliverables include:o a remote visualization resource of extreme capability (Longhorn):o 256 nodes (2048 processor cores, 24 Tflops peak) with 512 GPUs, 12 terabytes of aggregate memory, 200 terabytes of local system storageo tightly integrated with Ranger (the TeraGrid's inaugural Track2 system) to handle digital assets at the largest scale (and potentially future TACC HPC systems); 1. a comprehensive collection of open source and commercial end-user VDA software tools; 2. expert visualization support, including advanced interactive user support and training, from a team comprising many of the leading visualization researchers in the US; and 3. a framework for rapidly integrating new visualization technologies from leading research teams (including our own) to increase user capabilities throughout the project.aborative Visualization and Data Analysis for the National User Community
