MRI: Acquisition of High Speed Network Infrastructure for High Performance Distributed Computation in the Colleges of Science and Engineering

该合同将为购买思科10gb交换机和波分复用设备提供资金，用于在圣地亚哥州立大学（SDSU）计算科学研究中心（CSRC）、圣地亚哥超级计算机中心（SDSC）的TeraGrid中心和加州大学电信和信息技术研究所（CalIT2）的科学和工程研究小组之间构建一条三向高速数据链路。圣地亚哥（UCSD）。该网络基础设施将为SDSU物理化学、地球物理、天文学、生物信息学、热科学、燃烧工程、流体动力学、非线性动力学、海洋建模和计算机科学等领域的研究小组提供核心数据传输资源，这些研究小组经常使用SDSC和CalIT2计算资源。波分复用设备将实现两个校区之间的快速网络交易，从而使SDSU的研究人员能够快速将TeraGrid集群上生成的tb级数据传输回SDSU进行本地可视化和后处理。核心的10千兆位/秒交换机最初将连接SDSU两个独立学院的服务器机房设施：理学院和工程学院。该交换机还将提供几个额外的10千兆/秒接口，供各个研究实验室连接，从而在SDSU校园内形成高速研究骨干网络。将立即利用该网络基础设施的研究项目包括：(1)开发面向服务的体系结构/化学平衡网络基础设施和用于模拟合成气燃烧中燃气轮机NOx排放的动力学服务，(2)开发通用曲线海洋模型（GCOM）的网络基础设施，(3)软性反应中间体的计算量子力学研究，(4)模拟脉冲爆震发动机的高阶粒子源（PSIC）方法的数值研究；(5)开发PetaShake，这是TeraShake并行非弹性波模型（AWM）代码的PetaShake实现，可以使用数十亿网格点模拟地震场景。这些项目目前对现有的SDSU校园网络提出了很高的要求。SDSU的研究人员现在在交换数据集时需要更大的吞吐量和更短的延迟，这笔拨款将通过资助必要的设备来促进两所大学之间的快速数据传输，为SDSU和ucsd的网络连接提供急需的改进。除了教师和研究生使用外，这个网络基础设施将被本科生用于以下项目：1)计算机科学和计算机工程的高级论文研究项目；2)计算机网络、高速网络设计、客户端-服务器编程和分布式计算等课程的编程项目；3)在现有外部资助的奖学金项目下进行的本科生研究。作为全美授予少数族裔学士学位的前十所大学之一，圣地亚哥州立大学在为科学和工程研究中代表性不足的少数族裔提供这些机会方面占据了强势地位。

This award will fund the purchase of a Cisco 10 Gigabit/s switch and wavelength division multiplexing equipment to construct a three-way high-speed data link between science and engineering research groups affiliated with the Computational Science Research Center (CSRC) at San Diego State University (SDSU), the TeraGrid hub at the San Diego Supercomputer Center (SDSC), and the California Institute for Telecommunications and Information Technology(CalIT2) at the University of California, San Diego (UCSD). This network infrastructure will provide core data transmission resources for research groups at SDSU in physical chemistry, geophysics, astronomy, bioinformatics, thermal science, combustion engineering, fluid dynamics, nonlinear dynamics, ocean modeling, and computer science who routinely use SDSC and CalIT2 computing resources. The wavelength division multiplexing equipment will enable rapid network transactions between the two campuses, thereby allowing researchers at SDSU to rapidly transfer terabytes of data generated on TeraGrid clusters back to SDSU for local visualization and post-processing.The core 10 Gigabit/s switch will initially interconnect server room facilities at SDSU in two separate colleges: the College of Science and the College of Engineering. The switch will also provide several additional 10 Gigabit/s interfaces for individual research laboratories to connect and thereby form a high-speed research backbone network on the SDSU campus. Research projects that will immediately make use of this network infrastructure include (1) the development of a service oriented architecture/cyberinfrastructure of chemical equilibrium and kinetic services used to model gas turbine NOx emissions in syngas combustion, (2) the development of a cyberinfrastructure for the General Curvilinear Ocean Model (GCOM),(3) computational quantum mechanical studies of floppy reactive intermediates, (4) the numerical investigation of high-order particle-source-in-cell (PSIC) methods for the simulation of pulse detonation engines, and (5) the development of PetaShake, a petascale implementation of the TeraShake parallel Anelastic Wave Model (AWM) code that simulates earthquake scenarios using several billion grid points. These projects currently place heavy demands on the existing SDSU campus network. SDSU researchers now require greater throughput and shorter delay when exchanging datasets and this grant will provide a much needed improvement to SDSU-UCSD network connectivity by funding the necessary equipment to facilitate rapid data transfer between the two universities. In addition to faculty and graduate student use, this network infrastructure will be used by undergraduate students working on projects that include (1) senior thesis research projects in computer science and computer engineering, (2) programming projects in courses such as computer networking, high-speed network design, client-server programming, and distributed computing, and (3) undergraduate research carried out under existing, externally funded fellowship programs. SDSU occupies a strong position for making these opportunities available to minorities underrepresented in science and engineering research, as one of the top ten campuses in the nation granting bachelor's degrees to ethnic minorities.
