nicol, David M.达特茅斯学院ecise研究基础设施：物理几何算法的系统科学物理几何算法研究（PGA）研究计算或推理物理世界中的几何或空间关系的计算过程，以及它们在各种应用领域的实现。这些领域包括机器人，微机电系统（MEMS），计算生物学，科学和图像处理，图像分析和系统仿真。总的来说，这些技术处理与操纵与物理系统模型相关的大量数据相关的问题。PGA的研究追求这样一个命题：对于这样的系统，行为的预测、正确性的论证和组合精度都可以归结为几何分析。在有趣的规模上，这些领域都有共同之处，它们利用网络、远程数据库、本地区域集群、磁盘场（本地和远程）、并行处理和图形。该项目将开发新的系统科学技术（特别是算法、分析、建模技术和方法），用于解决这些应用程序的延迟、带宽、安全性、可扩展性、调度、访问的时间变化和并行高性能计算。这笔拨款提供的设备使我们的应用研究小组和系统研究小组能够协同开发针对这些关键性能问题的通用系统解决方案，并在应用和系统问题领域设定新的方向。

EIA-9802068Nicol, David M. Dartmouth CollegeCISE Research Infrastructure: Systems Science for Physical Geometric AlgorithmsResearch in Physical Geometric Algorithms (PGA) studies computational processes that compute or reason about geometric or spatial relationships in the physical world, and their realization in a variety of application areas. These areas include Robotics, Microelectromechanical Systems (MEMS), Computational Biology, Scientific and Image Processing, Image Analysis, and Systems Simulation. Collectively, these techniques take on the problems associated with manipulating massive amounts of data associated with a physical system model. Research in PGA pursues the proposition that, for such systems, predictions of behavior, arguments of correctness, and combinatorial precision devolve to a geometric analysis. At interesting scales these areas have in common their exploitation of networks, remote databases, local area clusters, disk farms (both local and remote), parallel processing, and graphics. This project will develop new Systems Science techniques (particularly algorithms, analysis, modeling techniques, and methodology) for addressing latency, bandwidth, security, scalability, scheduling, temporal variation in access, and parallel high-performance computing for these applications.The equipment provided by this grant enables our application research groups and systems research groups to synergistically develop common system solutions to these critical performance issues, as well as set new directions in both applications and systems problem areas.
