MRI: Acquisition of a High Performance Computing System for Online Simulation

该项目支持许多领域关键问题的在线模拟研究，旨在获得高性能计算系统。在线仿真代表了高性能计算的一种新模式，包括数据和仿真之间的紧密和连续的交互。数据可能来自仪器或存储库，或者可能源于用户与正在进行的计算的交互和转向。通常，模拟必须实时执行，也就是说，在时间尺度上，使基于模拟的决策。在线模拟需要高可用性、高吞吐量的计算设施，-专用于具有实时和交互需求的模拟;-在用户端以千兆比特的速度与先进的可视化设施联网，在数据端与仪器和储存库联网;和-足够强大，能够快速周转，支持高保真仿真决策。本地服务器通常支持在线仿真，因为国家超级计算机设施的配置不支持前两个。该设施将设在计算工程与科学研究所（ICES），该研究所已经在复杂系统的建模，大规模仿真和可视化方面建立了基础，并与德克萨斯大学埃尔帕索大学（一所少数民族大学）进行了现有的合作。多个实时模拟工作计划，包括-风暴潮建模; -神经肌肉接头模拟的在线可视化（只有真实的意义上的可视化是在线的）; -仪器油田;图像驱动的手术; -多尺度制造过程的模拟（只有真实的，因为它需要处理多尺度问题）; -基因组建模;实时疏散;和心血管模拟。

This project, supporting research in online simulation for critical problems in many areas, aims at acquiring a high-performance computing system. Online simulation represents a new paradigm in the use of high-performance computing, comprising a tight and continuous interaction between data and simulation. The data may stream from instruments or repositories, or may stem from user interaction with, and steering of, an on-going computation. Often, the simulations must execute in real-time, that is, in time scales that enable simulation-based decision making. Online simulation demands a high-availability, high-throughput computational facility, -Dedicated to simulations with real-time and interactive needs;-Networked at gigabits speeds with advanced visualization facilities on the user end, and instruments and repositories on the data end; and-Sufficiently powerful to enable fast turn-around in support of high-fidelity simulation-based decision-making.Local servers typically support online simulation, as national supercomputer facilities are not configured to support the first two. The facility will be housed in ICES (Institute for Computational Engineering and Sciences), already established in modeling, large-scale simulation, and visualization of complex systems, and with an existing collaboration with the University of Texas-El Paso, a minority-serving university. Multiple real-time simulation efforts are planned, including-Storm surge modeling; -Online visualization of simulations of neuromuscular junctions (only real in the sense visualization is on line); -Instrumented oil fields; Image-driven surgery; -Simulation of multi-scale manufacturing processes (only real in that it needs to deal with multi-scale issues); -Genomic modeling; Real-time evacuation; and Cardiovascular simulation.
