SI2-SSE: RADICAL Cybertools: Scalable, Interoperable and Sustainable Tools for Science

为了支持作为21世纪许多社会和智力挑战的基础的科学和工程应用，需要全面、平衡和灵活的分布式网络基础设施(DCI)。然而，设计和部署如此大规模的DCI的过程提出了一个关键的和具有挑战性的研究议程。一个具体的挑战是开发出一种工具，这种工具能够改变可使用DCI调查的问题的复杂性，同时具有可扩展性、易于部署和使用，并与其他各种现有工具兼容。激进的CyberTools将通过提供一套基于抽象的定义明确的功能来满足这些要求，这些功能的架构旨在支持一系列高性能和分布式计算基础设施上的可扩展、可互操作和可持续的科学。激进的CyberTools建立在重要的理论进步、生产软件开发的最佳实践以及仔细分析的使用和编程模型的基础上。激进的网络工具被提出在重大挑战问题上发挥作用，从个性化医疗和健康到理解长期的全球和地区气候。通过该项目开发的所有软件都将是开源的，并将在麻省理工学院许可证(MIT)下获得许可。Svn储存库的版本控制将通过http://radical.rutgers.edu.Existing访问，目前对激进网络工具的利用建立在激进网络工具的初步研究原型的基础上。然而，与研究原型相比，支持可扩展的最终用途科学所需的质量和能力有很大的不同。该项目的目的是弥合作为研究原型的能力与支持可扩展最终用途科学的挑战之间的差距。这将通过解决现有的可用性、功能性和可伸缩性方面的限制来实现。我们将通过利用在理解分布式系统和中间件方面的概念和理论上的进步来实现这一点，从而产生可扩展的体系结构和健壮的设计。我们将利用性能工程、数据密集型方法和网络基础设施方面的进步，提供下一代激进的网络工具。该项目将使现有的激进网络工具的研究原型更上一层楼，成为一个坚固、可扩展和可持续的工具，将支持更多的用户、应用程序类型和资源类型。

To support science and engineering applications that are the basis of many societal and intellectual challenges in the 21st century, there is a need for comprehensive, balanced, and flexible distributed cyberinfrastructure (DCI). The process of designing and deploying such large-scale DCI, however, presents a critical and challenging research agenda. One specific challenge is to produce tools that provide a step change in the sophistication of problems that can be investigated using DCI, while being extensible, easy to deploy and use, as well as being compatible with a variety of other established tools. RADICAL Cybertools will meet these requirements by providing an abstractions-based suite of well-defined capabilities that are architected to support scalable, interoperable and sustainable science on a range of high-performance and distributed computing infrastructure. RADICAL Cybertools builds upon important theoretical advances, production-software-development best practices, and carefully-analyzed usage and programming models. RADICAL Cybertools is posed to play a role in grand-challenge problems, ranging from personalized medicine and health to understanding long-term global and regional climate. All software developed through the project will be open source and will be licensed under the MIT License (MIT). Version control on the SVN repository will be accessible via http://radical.rutgers.edu.Existing and current utilization of RADICAL Cybertools is built upon preliminary research prototypes of RADICAL Cybertools. There is a significant difference, however, in the quality and capability required to support scalable end-usage science, compared to that of a research prototype. It is the aim of this project to bridge this gap between the ability to serve as a research prototype versus the challenges of supporting scalable end-usage science. This will be achieved by addressing existing limitations of usability, functionality, and scalability. We will do so by utilizing conceptual and theoretical advances in the understanding of distributed systems and middleware, resulting in a scalable architecture and robust design. We will employ advances in performance engineering, data-intensive methods, and cyberinfrastructure to deliver the next generation of RADICAL Cybertools. This project will take the existing research prototypes of RADICAL Cybertools to the next level towards becoming a hardened, extensible, and sustainable tool that will support a greater number of users, application types, and resource types.
