EIA 02-16661 Rafkin, Scot Chun, Robert San Jose State University Title: MRI/RUI/MII: Acquisition of a Linux Cluster Super Computer for Meteorological Modeling and Computer Science Research and Education Project Proposed:This proposal from an RUI/MII institution, establishing a Linux-based parallel computing cluster, aims to simulate meteorological phenomena and study and teach the use of parallel processors. The infrastructure will be used in support of ongoingNumerical modeling of the atmosphere of Mars using the Mars Regional Atmospheric Modeling System (MRAMS) andComputer Science Research in the parallel and distributed hardware and software.The first component will benefit the following current research underway:Large eddy simulations (LESs) of the Martian atmosphere to provide insight into the structure and dynamics of the highly unstable convective boundary layer (including the dynamics of dusts devils)Mesoscale simulations of past and proposed Mars landing sitesSimulation of local and regional dust storms, and wind-produced landforms (aids satellite observations)Simulations of orographic water ice and carbon dioxide clouds.The second component will investigate and/or exploreSoftware optimization of the MRAMS code (tune it for maximum performance on hardware platform) andAlternative hardware architectures for high-performance computingThe cluster will serve as a central research platform to investigate processor-to-processor communication overhead, memory contention of symmetric multiprocessors, cache coherence, and distributed processing. Moreover, performance of novel processor, memory, and network topologies will be evaluated.

EIA 02-16661 Rafkin，Scot Chun，Robert San Jose State University标题：MRI/RUI/MII：收购用于气象建模和计算机科学研究和教育的LINUX集群超级计算机项目建议：这是一家RUI/MII机构提出的建议，建立一个基于LINUX的并行计算集群，旨在模拟气象现象，研究和教授并行处理器的使用。该基础设施将用于支持正在进行的火星大气数值模拟，使用火星区域大气模拟系统(MRAMS)和并行和分布式硬件和软件的计算机科学研究。第一部分将有利于目前正在进行的以下研究：火星大气的大涡模拟(LESS)，以深入了解高度不稳定的对流边界层(包括尘埃的动力学)的结构和动力学；过去和计划中的火星着陆点的中尺度模拟；局部和区域沙尘暴的模拟，第二个组件将调查和/或开发MRAMS代码的软件优化(在硬件平台上调整它以获得最高性能)和用于高性能计算的替代硬件架构。该集群将作为中央研究平台，调查处理器到处理器的通信开销、对称多处理器的内存争用、高速缓存一致性和分布式处理。此外，还将评估新型处理器、内存和网络拓扑的性能。
