CC-NIE Networking Infrastructure: Enhancing the OrangeGrid - Upgrading the Syracuse Campus Network to Enable High Throughput Research Computing

锡拉丘兹大学的OrangeGrid使用HTCondor高吞吐量计算系统和一个定制的虚拟机管理器，允许办公室和学生实验室的空闲计算机运行研究计算任务。OrangeGrid拥有超过7000个CPU内核，并且还在不断增长，被雪城大学的研究和教学社区用于科学和工程应用。OrangeGrid的科学驱动程序来自各种各样的项目，包括引力波天文学、生物物理学、理论凝聚态物理学、计算流体动力学、高能物理学、地球科学、软物质物理学以及生物医学和化学工程。锡拉丘兹大学的CC-NIE网络基础设施项目升级了校园网络基础设施，以支持OrangeGrid上的数据密集型研究计算。该项目将校园主干网带宽从10Gbps提高到40Gbps，并为拥有橙网核心数量最多的建筑物提供10Gbps的链路。这个项目直接影响到OrangeGrid的可用性和生产力，将其开放给来自SU研究人员的更广泛的科学和工程项目。OrangeGrid是雪城大学教师和学生的重要资源。易于访问和强大功能的结合使得OrangeGrid对于没有自己的计算资源的初级研究人员和小团队来说尤其重要。工程与计算机科学学院和艺术与科学学院的本科生和研究生可以使用OrangeGrid，让他们早期体验高通量的研究计算。从运行OrangeGrid中获得的经验为其他希望利用桌面计算的未使用周期进行科学研究的大学提供了路线图。

Syracuse University's OrangeGrid uses the HTCondor High Throughput Computing System and a custom virtual machine manager to allow idle computers in offices and student labs to run research-computing tasks. With over 7000 CPU cores, and growing, OrangeGrid is used by Syracuse University's research and teaching community for science and engineering applications. Science drivers for OrangeGrid come from a diverse range of projects, including gravitational-wave astronomy, biological physics, theoretical condensed-matter physics, computational fluid dynamics, high-energy physics, Earth sciences, soft matter physics, and biomedical and chemical engineering.The CC-NIE Networking Infrastructure project at Syracuse University upgrades the campus network infrastructure to support data-intensive research computing on OrangeGrid. This project increases the campus backbone bandwidth from 10Gbps to 40Gbps and provides 10Gbps links to the buildings providing the largest number of OrangeGrid cores. This project directly affects the usability and productivity of OrangeGrid, opening it to a wider-range of science and engineering projects from SU researchers.OrangeGrid is an important resource for Syracuse University's faculty and students. The combination of easy access and power make OrangeGrid especially important to beginning researchers and small groups who do not have their own computing resources. Undergraduate and graduate students from the College of Engineering and Computer Science and the College of Arts and Sciences have access to OrangeGrid, giving them early experience with high-throughput research computing. The experiences gained from running OrangeGrid provide a road map for other universities who wish to leverage unused cycles from desktop computing for scientific research.
