Science and engineering depend increasingly on the ability to collaborate and federate resources across distances. This observation holds whether a single investigator is accessing a remote computer, a small team is analyzing data from an engineering experiment, or an international collaboration is involved in a multi-decade project such as the Large Hadron Collider (LHC). Any distributed collaboration and resource federation system requires methods for authentication and authorization, data movement, and remote computation. Of the many solutions that have been proposed to these problems, the Globus Toolkit (GT) has proven the most persistently applicable across multiple fields, geographies, and project scales. GT resource gateway services and client libraries are used by tens of thousands of people every day to perform literally tens of millions of tasks at thousands of sites, enabling discovery across essentially every science and engineering discipline supported by the NSF. As new, innovative techniques and technologies for collaboration and scientific workflows are developed, and as new computing and instrument resources are added to the national cyberinfrastructure, these technologies and other improvements must be added and integrated into GT so that it can continue to provide an advanced and robust technology for solving scientific research problems.The Sustain-GT project builds on past success to ensure that GT resource gateway services will continue to meet the challenges faced by NSF science and engineering communities. These challenges include: multiple-orders-of-magnitude increases in the volume of data generated, stored, and transmitted; much bigger computer systems and correspondingly larger and more complex computations; much faster networks; many more researchers, educators, and students engaged in data-intensive and computational research; and rapidly evolving commodity Web and Cloud computing environments. With the help of a new User Requirements Board, Sustain-GT will respond to community demands to evolve the GT resource gateway services with superior functionality, scalability, availability, reliability, and manageability. Sustain-GT will also provide the NSF community with high quality support and rapid-response bug fix services, as is required to sustain a heavily used, production system like GT.

科学和工程越来越依赖于跨距离协作和联合资源的能力。无论是单个研究人员访问远程计算机，还是一个小团队正在分析工程实验的数据，或者国际合作参与了大型强子对撞机（LHC）等数十年的项目，这种观察都是有效的。任何分布式协作和资源联合系统都需要用于身份验证和授权、数据移动和远程计算的方法。在针对这些问题提出的众多解决方案中，Globus Toolkit（GT）已被证明是最持久适用于多个领域、地理位置和项目规模的解决方案。GT资源网关服务和客户端库每天被成千上万的人使用，在数千个站点执行数千万个任务，使NSF支持的几乎所有科学和工程学科都能发现。随着用于协作和科学工作流程的新的创新技术和工艺的开发，以及随着新的计算和仪器资源被添加到国家网络基础设施，这些技术和其他改进必须加入并集成到GT中，以便它能够继续为解决科学研究问题提供先进和强大的技术。GT项目建立在过去的成功，以确保GT资源网关服务将继续满足NSF科学和工程社区面临的挑战。这些挑战包括：生成、存储和传输的数据量增加了几个数量级;更大的计算机系统和相应的更大、更复杂的计算;更快的网络;更多的研究人员、教育工作者和学生从事数据密集型和计算研究;以及快速发展的商品Web和云计算环境。在新的用户需求委员会的帮助下，Sustain-GT将响应社区的需求，以发展具有上级功能、可扩展性、可用性、可靠性和可扩展性的GT资源网关服务。Sustain-GT还将为NSF社区提供高质量的支持和快速响应的错误修复服务，这是维持像GT这样大量使用的生产系统所必需的。
