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、罗伯特圣何塞州立大学 标题：MRI/RUI/MII：采购 Linux 集群超级计算机用于气象建模和计算机科学研究和教育项目 提议：此提案来自 RUI/MII 机构，建立基于Linux的并行计算集群，旨在模拟气象现象并研究和教授并行处理器的使用。该基础设施将用于支持使用火星区域大气建模系统（MRAMS）和并行分布式硬件和软件中的计算机科学研究进行的火星大气数值建模。第一个组件将有利于当前正在进行的以下研究：大涡流火星大气模拟（LES），以深入了解高度不稳定的对流边界层的结构和动力学（包括尘暴的动力学）过去和拟议的火星登陆的中尺度模拟站点模拟当地和区域沙尘暴以及风产生的地貌（有助于卫星观测）模拟地形水冰和二氧化碳云。第二个部分将调查和/或探索 MRAMS 代码的软件优化（调整它以获得硬件上的最大性能）平台）和高性能计算的替代硬件架构集群将作为中央研究平台，研究处理器间的通信开销、对称多处理器的内存争用、缓存一致性和分布式 加工。此外，还将评估新型处理器、内存和网络拓扑的性能。
