A Proposed Enhancement of the Rhode Island Network for Computational Chemistry and Physics

在化学研究仪器和设施(CRIF)计划的支持下，布朗大学和罗德岛大学的化学系将获得一个计算机系统，以加强罗德岛计算化学和物理网络。该系统将由布朗和URI的Internet-2连接计算集群组成。每个机构的集群将具有由两个不同层组成的混合结构。第一层是用于CPU密集型、通信容忍型应用程序的自然计算服务器，它将由大量松散耦合的处理器组成。第二层专为通信密集型应用而设计，它将是一个更小、耦合更紧密的子群集。该设备将加强以下领域的研究：a)结构结构(Freeman)；b)液体的动力学行为(Stratt)；c)强量子系统激发态的产生(Nightingale)；以及d)多体量子动力学(DOLL)。一组快速、现代化的计算机工作站对于满足活跃的研究部门的计算需求至关重要。这种“计算机网络”还作为新的理论代码和算法的开发环境，提供最先进的图形和可视化设施，并支持对最先进的并行处理应用程序的研究。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Departments of Chemistry at Brown University and at the University of Rhode Island will acquire a computer system to enhance the Rhode Island Network for Computational Chemistry and Physics. The system will consist of Internet-2 linked computing clusters at Brown and URI. Clusters at each institution will have a hybrid structure composed of two distinct layers. Layer-I, the natural compute server for CPU-intensive, communications-tolerant applications, will consist of a larger number of loosely coupled processors. Layer-II, designed for more communications-intensive applications, will be a smaller, more tightly coupled sub-cluster. This equipment will enhance research in the following areas: a) structure structure (Freeman); b) the dynamical behavior of liquids (Stratt); c) the generation of excited states of strongly quantum systems (Nightingale); and d) many-body quantum dynamics (Doll). A cluster of fast, modern computer workstations is vital to serving the computing needs of active research departments. Such a "computer network" also serves as a development environment for new theoretical codes and algorithms, provides state-of-the-art graphics and visualization facilities, and supports research in state-of-the-art applications of parallel processing.
