DESCRIPTION (provided by applicant): This is a application to purchase a Computer Cluster to support seven NIH-funded research groups carrying out research in computational and structural biology, structural genomics, and proteomics. We propose to acquire 96 compute nodes with two quad-core processors each, for 768 processor cores in total. Compute nodes are linked by a low-latency Infiniband interconnect fabric for fine-grained parallel applications. The projects for which the requested equipment will be used include: Critical Tests of Biomolecular Dynamics (D. Case); Effective Potentials and Sampling Methods for Protein Folding and Binding (R. Levy and E. Gallicchio); In silico design of HIV vaccines and HIV RNase H inhibitors (E. Arnold and G.F. Arnold); NMR Investigation of Protein Folding and Misfolding (J. Baum); Automated NMR Protein Structure Determination and Refinement (G. Montelione); Computational studies of transcription regulation (A. Morozov); and Multi-scale Modeling of Nucleic Acids (W. Olson). These projects all have computationally intensive components that require computer resources beyond those available now at Rutgers. A key aspect of the proposed expansion is to obtain greater parallel capabilities needed for modern molecular dynamics and structure refinement studies. The public health-related relevance of the projects described in this application is highlighted in the two major goals of these projects. One goal is to further the understanding of aberrant structures of proteins that characterize misfolding disease states characteristic of Parkinson's, Alzheimer's, and similar diseases. A second major goal is to improve methods for the characterization of protein structures and assemblies as a basis for improving methods of structure based drug design for treatments of AIDS and other diseases. PUBLIC HEALTH RELEVANCE: This is a application to purchase a computer cluster to support eight NIH-funded investigators carrying out research in computational and structural biology, structural genomics, and proteomics. The public health related relevance includes study of aberrant structures of proteins that characterize misfolding disease states characteristic of Parkinson's, Alzheimer's, and similar diseases, and the characterization of protein structures and assemblies as a basis for improving methods of structure-based drug design for treatment of HIV/AIDS.

描述（由申请人提供）：这是购买计算机群集以支持七个由NIH资助的研究小组进行计算和结构生物学，结构基因组学和蛋白质组学研究的应用程序。我们建议将96个计算节点带有两个四核处理器，总共768个处理器核心。计算节点与用于细粒平行应用的低延迟Infiniband互连织物连接。使用请求的设备的项目包括：生物分子动态的关键测试（D. CASE）；蛋白质折叠和结合的有效电位和采样方法（R. Levy和E. gallicchio）；在HIV疫苗和HIV RNase H抑制剂（E. Arnold和G.F. Arnold）的硅硅设计中； NMR对蛋白质折叠和错误折叠的研究（J. Baum）；自动NMR蛋白结构的确定和改进（G. Montelione）；转录调控的计算研究（A. Morozov）；核酸（W. Olson）的多尺度建模。这些项目都有计算密集型组件，这些组件需要超出现在的Rutgers的计算机资源。提出的扩展的一个关键方面是获得现代分子动力学和结构改进研究所需的更大的平行能力。这些项目的两个主要目标强调了本申请中描述的项目与公共卫生相关的相关性。一个目标是进一步理解蛋白质的异常结构，这些结构是帕金森氏症，阿尔茨海默氏症和类似疾病的疾病特征的特征。第二个主要目标是改善表征蛋白质结构和组件的方法，作为改善基于结构的药物设计方法来治疗艾滋病和其他疾病的基础。 公共卫生相关性：这是购买计算机群集以支持八名由NIH资助的研究人员进行计算和结构生物学，结构基因组学和蛋白质组学研究的应用程序。与公共卫生相关的相关性包括研究蛋白质异常结构，这些蛋白质的异常结构表征了帕金森氏症，阿尔茨海默氏症和类似疾病的错误折叠疾病状态的特征，以及蛋白质结构和集会的表征作为改善基于结构的基于结构的HIV/AIDS药物设计方法的基础。
