CC-NIE Network Infrastructure: Bandwidth for Leadership in Advancing Science and Technology (BLAST)

田纳西大学诺克斯维尔分校（UTK）获得的“推进科学技术领导力的带宽”（BLAST）项目奖旨在显著改善田纳西州当地的广泛科学数据流，和国家科学和工程研究社区，将UTK校园连接到每秒100千兆位的国家网络，并将这种连接扩展到领导阶层，国家计算科学研究所（NICS）的高性能计算（HPC）设施。通过大幅提高所有类型的园区桥接、HPC资源之间的数据传输服务、数据归档和广域网文件系统的可用带宽，BLAST直接解决了领先的数据和计算密集型研究活动中科学发现的瓶颈问题。BLAST提供的网络基础设施升级提高了科学和工程研究的生产力，并通过使研究人员能够利用为科学数据流提供高性能网络带宽，以支持知识交流和科学发现。这种升级后的网络基础设施的一些应用实例包括改进的gridFTP数据传输、对档案和WAN文件系统的高性能访问以及与Globus Online的数据传输。BLAST项目还包括UTK、NICS和四个领先的数据和计算密集型研究项目之间的端到端网络性能调整合作，这些项目涉及地震模拟、数值天气预报、季节内和年代际时间尺度的地球气候研究，以及气候对公共卫生、水资源和能源影响的模拟研究。将向更广泛的社区传播所获得的信息和经验教训，以分享这一重要知识。

The Bandwidth for Leadership in Advancing Science and Technology (BLAST) project award to the University of Tennessee, Knoxville (UTK) is designed to significantly improving a wide range of science data flows for local, state of Tennessee, and national science and engineering research communities by connecting the UTK campus to the 100 gigabit per second national network and extending this connection to the leadership class high-performance computing (HPC) facilities at the National Institute for Computational Sciences (NICS). By dramatically improving the bandwidth available for all types of campus bridging, data transfer services to/from HPC resources, data archives, and wide-area network file systems, BLAST directly addresses bottlenecks to scientific discovery in leading data and compute intensive research activities.The network infrastructure upgrade provided by BLAST improves science and engineering research productivity and facilitates scientific discovery by enabling researchers to exploit high performance networking bandwidth for science data flows to support knowledge exchange and scientific discovery. Some examples uses of this upgraded network infrastructure include improved gridFTP data transfers, high-performance access to archives and WAN file systems, and data transfers with Globus Online. The BLAST project also includes end-to-end network performance tuning collaborations between UTK, NICS and four leading data and compute intensive research projects in earthquake simulation, numerical weather prediction, Earth climate research on intra-seasonal and inter-decadal time scales, and simulations for the study of climate effects on public health, water resources and energy. The information obtained and lessons learned will be disseminated to the broader community to share this important knowledge.
