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Terascale Facility （ETF）或TeraGrid涉及9个资源提供商，它们操作高性能计算、信息和可视化设施，通过专用光网络相互连接，并与一组通用软件集成，向用户社区提供一组内聚的资源和服务。2004年10月1日，TeraGrid将结束为期三年的建设工作，以创建这种分布式环境，并将过渡到可运行状态。该提案概述了一组将在加州理工学院（CIT）的高级计算研究中心（CACR）提供的服务，作为TeraGrid的一部分。CACR将通过一种以科学为基础的方法来支持TeraGrid，该方法侧重于数据密集型应用，最初由一小部分国家研究社区提供，这些社区具有以下特点：O有其他机构相关科研小组负责人参与；每个都反映了NSF或其他联邦研究机构的优先方向，主要是多机构感兴趣的领域。这些领域还将共享以下技术属性：o大量实验和/或计算数据保存在几个本地和远程异构集合中；O需要新的分析方法从实验数据中提取信息和/或与计算模型交互；O正在努力创建统一的、可互操作的服务；社区正在建立持久的虚拟组织来开发和联合信息资源。最初提出的主要研究领域是天文学和高能物理学。这两个领域都提供了与其他TeraGrid站点合作的机会，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将帮助这些组织在TeraGrid上部署和调整他们的软件，并提供支持以促进他们对TeraGrid的使用。此外，我们将开始与地球动力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，我们预计将确定共享网络基础设施的需求。CACR将运行一个由72个双处理器节点组成的Itanium2集群TF)。该集群通过Myrinet和千兆以太网与DataWulf集群紧密耦合，这将提供大约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交互计算和数据分析。因为CACR有一个集中的角色，它可以对按需交互计算和数据分析的初始研究社区需求做出响应。固有的灵活性将允许对调度和资源管理的新方法进行试验。在过去的二十年里，CACR和它的前身已经证明了与相对复杂的用户群体密切合作的能力，以探索创新的方法来支持计算科学前沿的科学家。我们建议继续这种合作模式。
