TeraGrid Extension: Bridging to XD

TeraGrid （TG）是一种先进的、全国分布的、开放的网络基础设施（CI），由超级计算、存储、分析和可视化系统、数据服务和科学网关组成，通过高带宽网络连接，通过协调的政策和操作集成，并由计算和技术专家提供支持，从而实现和支持前沿的科学发现，促进科学和技术教育。TG在几乎所有的科学和工程领域都取得了许多科学成就。TG是由需要计算资源和服务的研究人员和教育工作者推动的，这些资源和服务在他们的本地/校园环境中是极其困难或不可能获得的。TG资源的大部分用于支持由TG的高级CI资源支持的同行评审的科学和工程项目。然而,小?任何愿意申请的个人都可以获得拨款。通过其员工，资源和服务的协调能力，TG通过专家和专家用户团队高度熟练地利用TG资源，实现了尖端的，通常是变革性的科学和工程。此外，TG还支持更广泛的社区，包括更大的、以领域为重点的用户组，这些用户组可能不具备特定的高性能计算技能，但正在处理重要的科学研究和教育问题。TG活动的更广泛影响包括拓展到传统HPC用户之外的社区，提高学校和科学博览会中未来科学家对计算和数据挖掘能力的认识，以及传播TG关于如何构建网络基础设施以及如何将其带到用户社区的知识。高级支持将研究人员与TG专家联合起来，以提高效率和生产力，定义最佳实践，并创建新功能早期采用者的先锋。对Science gateway的支持为TG资源提供了社区设计的接口，并向更广泛的用户扩展了对数据收集、社区协作工具和可视化功能的访问。在TG上执行变革性的科学和工程依赖于其协同工作的资源，这需要一个协调的用户支持系统、用户访问和信息的集中机制、一个通用的分配过程和分配管理，以及一个协调的用户环境。在这个用户支持环境的基础上，TG维护一个健壮的、集中管理的基础设施，用于网络、安全和身份验证以及操作服务。在这一年的延期中，TG将。* 2011年继续支持一些资源。这包括轨道2系统，people (PSC)，一个对许多新用户特别有用的共享内存系统，三个IA32-64集群和一个使用闪存和虚拟SMP节点的新资源DASH （SDSC）。*允许高通量、开放科学网格式作业。*促进互操作性和技术共享的探索。*为来自校级或系级资源的用户提供一个过渡平台。*支持独特的计算平台和海量存储系统。*整合来自其他OCI奖项的新系统。*在培训、教育和外联方面作出积极努力，以保持更大、更多样化的社区推动科学发现。*参与代表性不足的社区，并继续建立强有力的合作伙伴关系，以提供最好的高性能计算学习和劳动力发展计划，并增加准备充分的STEM研究人员和教育工作者的数量。

The TeraGrid (TG) is an advanced, nationally distributed, open cyberinfrastructure (CI) comprised of supercomputing, storage, analysis, and visualization systems, data services, and science gateways, connected by high-bandwidth networks, integrated by coordinated policies and operations, and supported by computing and technology experts, that enables and supports leading-edge scientific discovery and promotes science and technology education. The TG has enabled numerous scientific achievements in almost all fields of science and engineering. The TG is driven by researchers and educators requiring computational resources and services which would be extremely difficult or impossible to obtain in their local/campus environments. The largest fraction of TG resources are used in the support of peer-reviewed scientific and engineering projects enabled by the advanced CI resources of the TG. However, ?small? allocations are available to any individual willing to apply. Through the coordinated capabilities of its staff, resources, and services, TG enables cutting-edge, often transformative science and engineering, by experts and expert teams of users making highly-skilled use of TG resources. In addition, the TG also supports a wider community of much larger, domain-focused groups of users that may not possess specific high-performance computing skills but who are addressing important scientific research and education problems. The broader impact of TG activities include outreach to communities beyond the traditional set of HPC users, raising the awareness of future scientists in schools and science fairs on the power of computation and data mining, and spreading TG knowledge about how to build cyberinfrastructure, and how to bring it to the user community. Advanced support joins researchers with TG experts to increase efficiency and productivity, define best practices, and create a vanguard of early adopters of new capabilities. Support for Science Gateways provides community-designed interfaces to TG resources and extends access to data collections, community collaboration tools, and visualization capabilities to a much wider audience of users. Performing transformative science and engineering on the TG depends on its resources working in concert, which requires a coordinated user support system, centralized mechanisms for user access and information, a common allocations process and allocations management, and a coordinated user environment. Underlying this user support environment, the TG maintains a robust, centrally managed infrastructure for networking, security and authentication, and operational services. In this one year extension, the TG will.* Continue to support several resources into 2011. This includes the Track 2 systems, Pople (PSC), a shared memory system particularly useful to a number of newer users, three IA32-64 clusters and a new resource employing flash memory and virtual SMP nodes called DASH (SDSC).* Allow high-throughput, Open Science Grid-style jobs.* Enable exploration of interoperability and technology sharing.* Provide a transition platform for users coming from university- or departmental-level resources.* Support unique compute platforms and massive storage systems.* Integrate new systems from additional OCI awards.* Provide vigorous efforts in training, education and outreach to retain larger and more diverse communities in advancing scientific discovery.* Engage under-represented communities, and continue to build strong partnerships in order to offer the best possible HPC learning and workforce development programs and increase the number of well-prepared STEM researchers and educators.
