Scientific Supercomputing, Visualization, and Animation in Geotechnical Earthquake Engineering & Engineering Seismology

这项行动是为了支持一个研讨会，以解决使用先进的计算机体系结构来解决岩土地震工程和强地震动地震学中的大规模问题，包括可视化和动画技术的应用。讲习班将于1994年秋季举行。讲习班将召集来自学术界、工业界和政府的选定的研究人员和实践者交流信息和想法，并为这项技术的使用提供广泛的指导方针。随着超级计算机的出现，地震工程师和地震学家已经开始主要借助矢量多处理器来解决具有重大实际意义的问题，例如对土坝和冲积盆地地震反应的三维分析。在未来五年内，原始计算能力的预期增长将不足以成功地理解和预测大型系统的地震反应，除非同时在物理建模、数值近似、并行算法和新一代高性能并行系统的软件工具方面取得进展。计算过程的另一个重要方面是需要处理和理解大量的数值数据，这是工程活动（如现场和实验室实验）所共有的。近年来，先进的可视化和动画技术已经发展起来，以协助分析和解释这些大型数值数据集。因此，本讲习班将讨论与使用先进的计算机体系结构和可视化技术用于减轻地震灾害有关的这些不断变化的趋势。＊＊＊

9419696 Bielak This action is to support a workshop to address the use of advanced computer architectures for the solution of large-scale problems in geotechnical earthquake engineering and strong ground motion seismology, including the application of visualization and animation techniques. The workshop is to be held in the Fall of 1994. The workshop will convene selected researchers and practitioners from academia, industry and government to exchange information and ideas, and to provide broad guidelines for the use of this technology. With the advent of supercomputers, earthquake engineers and seismologists have begun to address, mainly with the help of vector multiprocessors, problems of great practical interest, such as the three-dimensional analysis of the seismic response of earthdams and alluvial basins. Anticipated increases in raw computing power over the next five years will not be sufficient for the successful understanding and prediction of the earthquake response of large systems, unless simultaneous advances are made in physical modeling, numerical approximations, parallel algorithms, and software tools for the new generation of high performance parallel systems. Another important aspect of the computational process, which is shared by engineering activities such as field and laboratory experiments, is the need to process and understand vast amounts of numerical data. In recent years advanced visualization and animation techniques have been developed to assist in analyzing and interpreting these large numerical data sets. Thus this workshop will discuss these evolving trends associated with the use of advanced computer architectures and visualization techniques as applied to earthquake hazard mitigation. ***
