XROADS: Planning the Future eXtreme Digital Cyberinfrastructure

该项目是一个为期15个月的规划活动，旨在为TeraGrid项目的后继者开发设计。 这项活动将使研究人员和教育工作者参与系统要求的完善和验证。该项目包括为eXtreme Digital（XD）集成服务开发详细的科学案例、操作概念、设计和实施计划。 TeraGrid XD下一阶段的主要目标是通过为研究人员和教育工作者提供可用的极端规模的数字资源，超越典型校园中通常可用的资源，以及接口，提供必要的咨询支持和培训，以促进其使用。 XD的目标是在设计和实施有效、高效、日益虚拟化的高端数字服务提供方法方面进行创新。极端数字化服务--面向研究人员和教育工作者。 XD基础设施旨在将极端规模的数字资源和服务整合到一个通用框架中，使研究人员能够轻松利用多种资源和服务，包括在单一的集成环境中使用本地资源和国家资源的能力。 拟议的活动是一个项目的规划活动，如果成功，将为科学和工程领域的广泛研究和教育提供基础设施。 除了作为职业研究人员的用户之外，可以合理地预期，每年将有数百名研究生和博士后研究人员使用该基础设施作为其研究的一部分。 规划活动包括与许多领域的科学家和工程师进行外联。

This project is a fifteen-month planning activity to develop a design for the successor to the TeraGrid project. This activity will engage researchers and educators in the refinement and validation of system requirements. The project includes the development of a detailed science case, concept of operations, design, and implementation plan for the eXtreme Digital (XD) Integrating Services. The primary goal of the next phase of the TeraGrid, XD, is to enable major advances in science and engineering research, in the integration of research and education, and in broadening participation in science and engineering by under-represented groups, by providing researchers and educators with usable access to extreme-scale digital resources, beyond those typically available on a typical campus, together with the interfaces, consulting support and training necessary to facilitate their use. The target for XD is innovation in the design and implementation of an effective, efficient, increasingly virtualized approach to the provision of high-end digital services ? extreme digital services - for researchers and educators. The XD infrastructure is intended to integrate extreme-scale digital resources and services into a common framework that makes it easy for researchers to take advantage of multiple resources and services, including the ability to move between using local resources and national resources within a single, well integrated environment. The proposed activity is a planning activity for a project that, if successful, will provide infrastructure for research and education across a broad range of areas in science and engineering. In addition to users who are career researchers, it can reasonably be expected that this infrastructure will be used by several hundred graduate students and post-doctoral researchers each year as part of their research. The planning activity includes outreach to scientists and engineers from many fields.
