[202048] wise, David S.Indiana University - Bloomington RI：协作、高性能网格应用的研究基础设施该项目为分布式高性能计算开发实验性基础设施，支持十个研究项目，将网格为计算资源提供的位置透明性扩展到最终用户需要的所有活动。正在研究的服务包括软件开发、并行代码中间件、用于科学计算的分布式软件组件、并行远程方法调用的安全性、管理大规模数据流以及协作方法。这项研究建立并扩展了该机构与几个国家电网研究团队的合作。与通过生产机器提供的现有国家和大学基础设施不同，这项研究需要一个能够容忍实验性网络协议、临时中间件和其他系统级更改的环境。基础设施将有助于以下研究项目：Opie：并行矩阵算法的基础工作，在许多架构平台上实现高效率。LAM：中间件MPI实现，支持分层和容错并行计算。dQUOB：将SQL查询应用于实时数据流。RMI安全性：对远程方法调用安全机制的基础研究，允许在安全性与效率之间进行权衡。HPJ：高性能Java，为可移植的高性能编码创建语言平台。网格代理：可靠、健壮的发布/订阅服务，用于在分布式网格环境中引入容错功能。社区网格协作实验室：具有远程教育和分布式社区应用程序的高级协作功能。输出：远程仪器访问方法的设计和由此产生的超大数据集的数据管理。软件组件：分布式软件组件模型，设计用于在广域网格环境中使用并行计算“节点”的应用程序。科学门户：一组工具，允许程序员构建从桌面环境和web浏览器访问和控制的网格分布式应用程序。支持所有这些项目的基础设施的主要改进包括一个16节点循环服务器和一个大型文件服务器，以及对建筑内部和内部的网络升级。

0202048Wise, David S.Indiana University - Bloomington RI: A Research Infrastructure for Collaborative, High-Performance Grid ApplicationsThis project, developing an experimental infrastructure for distributed high performance computing, supports ten research projects extending the location-transparency that the Grid provides for computation resources to the full spectrum of activities which end-users require. Services being explored include software development, parallel code middleware, distributed software components for scientific computing, security for parallel remote method invocation, managing large-scale data streams, and collaboration methodologies. The research builds on and extends the institutions collaborations with several national Grid research teams. In contrast to existing national and university infrastructure available through production machines, this research requires an environment tolerant of experimental network protocols, temporary middleware, and other system-level changes. The infrastructure will contribute to the following research projects:a. Opie: basic work on parallel matrix algorithms that achieve high efficiency across many architectural platformsb. LAM: middleware MPI implementations supporting hierarchical and fault-tolerant parallel computingc. dQUOB: application of SQL queries to live data streamsd. RMI Security: basic research into security mechanisms for remote method invocation, allowing security to be traded off with efficiencye. HPJ: High Performance Java creating a language platform for portable high performance codingf. Grid Broker: reliable, robust publish/subscribe service for introducing fault tolerance into the distributed Grid environmentg. Community Grids Collaboratory: advanced collaboration capabilities with applications to both distance education and distributed communitiesh. Xports: design of methodologies for remote instrument access and data management of the resulting extremely large data setsi. Software Components: distributed software component model designed for applications that use parallel computing "nodes" in wide-area Grid environmentsj. Science Portals: set of tools that allow programmers to build Grid distributed applications accessed and controlled from desktop environments and web browsersMajor improvements to infrastructure supporting all these projects include a 16-node cycle server and a large-scale file server as well as network upgrades to and within the building.
