9512241亨德森 拟议项目将收购SGI Power Onyx图形引擎前端和SGI Power Challenge计算引擎，用于大规模计算转向。计算转向允许用户通过图形用户界面交互地改变边界条件、模型几何形状和计算参数。它允许可视化指导或操纵仿真或计算的设计和计算阶段。计算转向模型适用于广泛的应用，包括医学，遗传学，图像分析，CAD/CAM，遥控机器人和虚拟现实。正在不同的应用领域开发软件，以“闭环”取代典型的模拟模型，在这种模型中，用户手动设置输入参数，计算结果，存储数据，通过单独的可视化包可视化结果，然后从头开始。拟议的设备将允许交互式建模和科学可视化的并行计算系统的支持。 ***

9512241 Henderson The proposed project is to acquire an SGI Power Onyx graphics engine front end, and a SGI Power Challenge computational engine for large-scale computational steering. Computational steering permits users to interactively change boundary conditions, model geometry, and computational parameters via a graphical user interface. It allows the visualization to guide or steer the design and computation phases of the simulation or computation. The computational steering model is applicable to a wide range of applications including medicine, genetics, image analysis, CAD/CAM, telerobotics, and virtual reality. Software is being developed in different application areas to "close the loop" to replace the typical simulation model in which the user manually sets input parameters, computes results, stores data, visualizes the results via a separate visualization package, and then starts again at the beginning. The proposed equipment will permit interactive modeling and scientific visualization supported by parallel computational systems. ***
