32 processor SGI Onyx 3800 w/64 GB memory and 1 TB disk

描述(由申请人提供)：为了高性能计算和可视化，来自明尼苏达大学的14名主要用户正在申请资金，以购买配备无限现实3图形引擎的32处理器SGI Onyx 3800，GB内存(每个处理器2 GB)和1 TB光纤通道RAID。这14个主要用户拥有13项NIH RO1类型的研究资助，涵盖生物医学研究的各个领域：X射线衍射和核磁共振蛋白质和核酸结构测定(Banaszak，Levitt，Mayo，Ohlendorf)，酶系统的量子力学计算(Barry，Gao，Truhlar，York)，肌肉运动的分子动力学模拟(Thomas)和生物分子动力学(Cramer，Mayo，Musier-Forsyth)，以及共焦(Wessendorf，Wilcox)和扫描电子显微镜(Erlandsen)细胞和组织的显微成像。拟议的设备将安置在明尼苏达大学西岸校区新的基础科学和生物医学工程大楼的基础科学计算实验室(BSCL)相对较新的空间。虽然BSCL提供了大量的计算技术专长，但目前提供的计算资源包括11个SGI工作站(其中7个已有两年以上的历史)和3个已有两年历史的四处理器计算服务器。这种仪器不足以满足拟议研究项目的计算需求，也不能提供参与NLH资助的研究人员所需的高端图形能力。拟议的设备将提供BSCL目前无法提供的计算和图形能力。

DESCRIPTION (provided by applicant):For high-performance computing and visualization, a group of 14 major users from the University of Minnesota is requesting funds towards the purchase of a 32-processor SGI Onyx 3800 with the Infinite Reality 3 Graphics engine, 64 GB of memory (2 GB per processor) and 1 TB of fibre channel RAID. These 14 major users have 13 NIH RO1-type research grants among them covering various areas in biomedical research: X-ray diffraction and NMR protein and nucleic acid structure determination (Banaszak, Levitt, Mayo, Ohlendorf), quantum mechanical calculations of enzyme systems (Barry, Gao, Truhlar, York), molecular dynamics simulations of muscle motion (Thomas) and biomolecular dynamics (Cramer, Mayo, Musier-Forsyth), and confocal (Wessendorf, Wilcox) and SEM (Erlandsen) microscopic imaging of cells and tissues. The proposed equipment will be housed in relatively new space of the Basic Sciences Computing Lab (BSCL) in the new Basic Sciences and Biomedical Engineering building on the west bank campus of the University of Minnesota. Although considerable computational technical expertise is available at the BSCL, computing resources currently offered comprise eleven SGI workstations (seven of which are more than two years old) and three two-year-old four-processor compute servers. This instrumentation is inadequate to meet the computing needs of the proposed research projects and does not provide the high-end graphics capability required by participating NlH-funded researchers. The proposed equipment will provide computing and graphics capabilities that are currently unavailable at the BSCL.
