Strategies for Remote Visualization on a Dynamically Configurable Testbed

现代科学研究越来越依赖于仿真和分析，需要高性能计算机、分布式大规模数据和高速网络。这个项目，在动态可配置的测试平台上的远程可视化策略，将使用一个集成的，面向应用程序的设计和开发方法来构建高度优化的分布式应用程序。这些应用程序将使用网络服务作为第一类资源，以及分布式计算，存储和可视化资源。特别是，该项目将研究大数据分布式可视化的新策略，原型设计一个先进的分布式体绘制系统，结合用户控制的网络服务，高速数据流，高质量的视频流和并行GPU加速的交互式渲染。与分布式国家（路易斯安那州立大学、国家能力自我评估、荷兰国家资源局、泰国气候变化咨询委员会）和国际（马萨里克大学）合作者，以及网络提供商（Internet2，LONI，OmniPop，ESNET）该项目将建立一个现实世界的测试平台，用于战略的实施和评估。智力优点该项目同时解决分布式计算和计算科学中的问题，从根本上说，它的目标是发展和增强国家网络基础设施，以使科学发现能够在日益增加的大型和复杂的计算环境中进行，例如NSF的TeraGrid、XD、Blue沃茨和DataNet计划所提供的计算环境。利用Internet2的动态可配置网络服务，将提供一个持久的实验环境，将被一系列应用程序组用于原型和实验分布式应用程序。该测试平台将提供给40多名学生和博士后，他们在路易斯安那州的NSF EPSCOR研究基础设施改进奖的网络基础设施部分工作。

Modern scientific research is increasingly dependent on simulation and analysis requiring high performance computers, distributed large-scale data and high-speed networks. This project, Strategies for Remote Visualization on a Dynamically Configurable Testbed, will use an integrated, application-oriented design and development approach to build highly-optimized distributed applications. These applications will use network services as first class resources, together with distributed compute, storage, and visualization resources. In particular, the project will investigate new strategies for distributed visualization of large data, prototyping an advanced distributed volume rendering system combining user-controlled network services,high-speed data streaming, high-quality video streaming and parallel GPU-accelerated interactive rendering. Working with distributed national (LSU, NCSA, ORNL, TACC) and international (Masaryk University) collaborators, as well network providers (Internet2, LONI, OmniPop, ESNET) the project will build a real-world testbed for implementation and evaluation of strategies.Intellectual MeritThis project simultaneously addresses issues in distributed computing and computational science, and is fundamentally targeted at the development and enhancement of a national cyberinfrastructure to enable scientific discovery on increasing large and complex computing environments such as provided by the NSF's TeraGrid, XD, Blue Waters and DataNet programs.Broader ImpactThe real-world testbed, utilizing Internet2's Dynamically Configurable Network service, will provide a persistent experimental environment that will be used by a range of application groups to prototype and experiment distributed applications. The testbed will be available to over forty students and postdocs working in the cyberinfrastructure component of Louisiana's NSF EPSCOR Research Infrastructure Improvement award.
