Efficient analysis of dynamic networks is highly important in diverse multidisciplinary real-life applications, such as data mining and analytics, social and biological networks, epidemiology, cyber-physical infrastructures, transportation networks, surface mining, and cybersecurity. Although numerous software exists for analyzing static networks, a comprehensive cyberinfrastructure that supports innovative research challenges in large-scale, complex, dynamic networks is lacking. This multi-university proposal addresses this gap by developing a novel platform, called CANDY (Cyberinfrastructure for Accelerating Innovation in Network Dynamics), based on efficient, scalable parallel algorithm design for dynamic networks and high-performance software development with performance optimization. For broader impact and outreach activities, the investigators will (1) collaborate with multidisciplinary research groups to evaluate the effectiveness of the developed platform, algorithms and software tools; (2) host workshops, webinars, and tutorials to educate research community about the cyberinfrastructure; (3) disseminate project outcomes via a dedicated website, keynote and invited talks, demos, and high-quality publications in peer-reviewed journals and conferences; and (4) train next generation data scientists in the development of CANDY platform, by engaging women and underrepresented minority students, including high school students and rural communities in Missouri, Hispanic and African-American communities in Texas, and First Nation (Native American) community in Oregon.This project will develop the first parallel, scalable, extendable, and user-friendly software platform for updating important properties of dynamic networks. It will also provide the requisite functionalities and tools to modify existing algorithms or create new ones, catering to basic, intermediate and advanced users with different levels of expertise. The CANDY cyberinfrastructure platform will be implemented on different architectures, such as distributed memory, shared memory, and graphics processor units providing user-friendly interfaces. Significant research and development innovations include: (1) a novel hierarchical taxonomy of network analysis algorithms that allows for layered specification of parallel algorithms based on multiple parameters; (2) templates for creating new scalable algorithms for dynamic network analysis; (3) algorithms to partition the streaming set of nodes and edges into network snapshots at changing points; and (4) invariant-based quantifiable performance metrics for analyzing large-scale dynamic networks. As a case study, the developed software will be evaluated on two disparate domains -- fast processing of genomic data on dynamic trees, and cost-effective operation of complex mining engineering applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

动态网络的有效分析在各种多学科的现实生活应用中非常重要，例如数据挖掘和分析，社会和生物网络，流行病学，网络物理基础设施，运输网络，地表采矿和网络安全。虽然存在许多用于分析静态网络的软件，但缺乏支持大规模，复杂，动态网络中创新研究挑战的综合网络基础设施。这项多所大学的提案通过开发一个名为CANDY（加速网络动态创新的网络基础设施）的新平台来解决这一差距，该平台基于动态网络的高效，可扩展的并行算法设计和具有性能优化的高性能软件开发。为了更广泛的影响和推广活动，研究人员将（1）与多学科研究小组合作，评估所开发的平台，算法和软件工具的有效性;（2）举办研讨会，网络研讨会和教程，以教育研究界关于网络基础设施;（3）通过专门的网站、主题演讲和特邀演讲、演示以及同行评审期刊和会议上的高质量出版物传播项目成果;以及（4）通过让女性和代表性不足的少数民族学生参与CANDY平台的开发，培训下一代数据科学家，包括密苏里州的高中生和农村社区，德克萨斯州的西班牙裔和非洲裔美国人社区，以及第一民族（美国土著）社区在俄勒冈州。该项目将开发第一个平行的，可伸缩的，可扩展的，和用户友好的软件平台，用于更新动态网络的重要属性。它还将提供必要的功能和工具，以修改现有算法或创建新算法，满足具有不同专业知识水平的初级、中级和高级用户的需求。CANDY网络基础设施平台将在不同的架构上实施，例如分布式存储器、共享存储器和提供用户友好界面的图形处理器单元。重要的研究和开发创新包括：（1）一种新的网络分析算法的层次分类法，它允许基于多个参数的并行算法的分层规范;（2）用于创建用于动态网络分析的新的可扩展算法的模板;（3）将节点和边的流集合划分为变化点处的网络快照的算法;以及（4）用于分析大规模动态网络的基于不变量的可量化性能度量。作为一个案例研究，开发的软件将在两个不同的领域进行评估-快速处理动态树上的基因组数据，以及复杂采矿工程应用程序的成本效益操作。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估。
