The Extensible Terascale Facility (ETF), or TeraGrid, involves nine resource providers operating high-performance computing, information, and visualization facilities, interconnected with a dedicated optical network and integrated with a set of common software that presents the user community with a cohesive set of resources and services. On October 1, 2004, the TeraGrid will conclude a three-year construction effort to create this distributed environment and will transition into an operational state. This proposal outlines a set of services to be provided at the Center for Advanced Computing Research (CACR) of the California Institute of Technology (CIT) as part of the TeraGrid. CACR will support the TeraGrid through a science-based approach focused on data-intensive applications, initially from a small set of national research communities sharing the following features: o there is a strong related scientific research group at CIT; o there is participation by leaders of related scientific research groups at other institutions; and o each reflects a priority direction for NSF or other federal research agencies, primarily multi-agency areas of interest. These areas will also share the following technical attributes: o large quantities of experimental and/or computational data are maintained in several local and remote heterogeneous collections; o there are requirements for new analysis approaches to extract information from the experimental data and/or interact with computational modeling; o there is an ongoing effort to create unified, interoperable services; and o the communities are building persistent virtual organizations that exploit and federate information resources. The proposed initial primary research communities are astronomy and high energy physics. Both areas offer opportunities for collaboration with other TeraGrid sites and each community has significant funding to develop domain specific cyberinfrastructure. CACR will assist these groups in deploying and tuning their software on the TeraGrid and provide support to facilitate their TeraGrid usage. In addition, we will initiate efforts with the geodynamics modeling and neutron physics communities. Since the problems faced by these user communities have common features, we anticipate identifying requirements for shared cyberinfrastructure. CACR will operate an Itanium2 cluster consisting of 72 dual processor nodes (.8 TF). This cluster is tightly coupled via Myrinet and Gigabit Ethernet to DataWulf clusters, which will provide approximately 170 TB of online disk storage. These resources will be utilized primarily for application development and for on-demand and interactive computation and data analysis. Because CACR has a focused role, it can be responsive to the initial research communities requirements for on-demand and interactive computation and data analysis. Inherent flexibility will allow experimentation with novel approaches to scheduling and, in general, resource management. For the past two decades, CACR and its predecessors have demonstrated an ability to work closely with relatively sophisticated user groups to explore innovative approaches to supporting scientists on the frontier of computational science. We propose to continue this mode of collaboration.

可扩展的Terascale设施（ETF）或Teragrid涉及9个资源提供商，运行高性能计算，信息和可视化设施，与专用的光学网络互连，并与一组通用软件集成，该软件与用户社区一起使用凝聚力的资源和资源集合集合。 2004年10月1日，Teragrid将结束为期三年的建设工作，以创建这个分布式环境，并将过渡到运营状态。 该提案概述了加利福尼亚理工学院（CIT）的高级计算研究中心（CACR）作为Teragrid的一部分提供的一系列服务。 CACR将通过以科学为基础的方法来支持Teragrid，该方法最初来自一小部分国家研究社区，分享了以下功能：o CIT有一个强大的相关科学研究小组； o其他机构的相关科学研究小组的领导人参与； o每个都反映了NSF或其他联邦研究机构的优先指导，主要是感兴趣的多机构领域。这些领域还将共享以下技术属性：o在几个本地和远程异质集合中维持大量实验和/或计算数据； o新分析方法有一些要求从实验数据中提取信息和/或与计算建模相互作用的要求； o正在进行的努力来创建统一的可互操作服务； o社区正在建立持久的虚拟组织，以利用和联合信息资源。拟议的初始研究社区是天文学和高能量物理学。 这两个领域都为与其他Teragrid网站的合作提供了机会，每个社区都有大量资金来开发特定领域的网络基础设施。 CACR将协助这些小组在Teragrid上部署和调整其软件，并提供支持以促进其TeraGRID使用情况。此外，我们将开始使用地球动能学建模和中子物理社区的努力。由于这些用户社区面临的问题具有共同的特征，因此我们预计确定共享网络基础结构的要求。 CACR将操作一个由72个双处理器节点（.8 TF）组成的ITANIUM2群集。该群集通过Myrinet和Gigabit以太网紧密耦合到DataWulf群集，该集群将提供大约170 TB的在线磁盘存储。 这些资源将主要用于应用程序开发以及按需和交互式计算和数据分析。 由于CACR具有重点的作用，因此它可以响应对按需和交互式计算和数据分析的初始研究社区要求。固有的灵活性将允许实验新颖的调度方法，并且通常是资源管理。在过去的二十年中，CACR及其前任证明了与相对复杂的用户群体紧密合作的能力，以探索在计算科学领域支持科学家的创新方法。我们建议继续这种协作方式。
