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

该项目支持多个领域关键问题的在线仿真研究，旨在获得一个高性能的计算系统。在线仿真代表了使用高性能计算的一种新范式，包括数据和仿真之间紧密而连续的交互。数据可能来自仪器或储存库，也可能源于用户与正在进行的计算的交互和引导。通常，模拟必须实时执行，也就是以时间尺度执行，以实现基于模拟的决策。在线仿真需要高可用性、高吞吐量的计算设施--专门用于具有实时和交互需求的仿真；-以千兆位的速度与用户端的先进可视化设施以及数据端的仪器和储存库联网；以及-足够强大，以支持基于高保真仿真的决策的快速周转。本地服务器通常支持在线仿真，因为国家超级计算机设施没有配置为支持前两者。该设施将设在ICES(计算工程与科学研究所)，该研究所已经建立了复杂系统的建模、大规模模拟和可视化，并与德克萨斯大学埃尔帕索分校现有的合作，这是一所少数族裔服务的大学。计划进行多项实时模拟工作，包括-风暴潮建模；-神经肌肉接头模拟的在线可视化(仅在感觉上可视化是真实的)；-仪表化油田；-图像驱动的手术；-多尺度制造过程的模拟(仅真实，因为它需要处理多尺度问题)；-基因组建模；-实时疏散；以及心血管模拟。

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.
