摘要
高性能计算技术以分布式计算资源和网络技术为基础,依托高端并行计算技术和可视化,可高效地解决大型复杂结构高精度分析、优化和控制等问题,从而促进工程结构设计水平和设计质量的提高。近年来,我国土木工程正处于高速发展时期,随着计算机软硬件技术的发展,常规的工程设计有限元分析和设计计算已经普及。而由于超高、超长、大跨度等复杂工程的大量涌现,工程结构设计中对高性能计算的需求越来越迫切。高性能计算是指运用有效的算法,快速完成科学研究、工程设计、金融、工业以及社会管理等领域内具有数据密集型、计算密集型和I/O(数据输入输出)密集型的计算。本文概要地介绍了高性能计算技术的有关概念、国内外发展现状,以及在工程结构分析中应用的最新进展,供工程设计人员参考。
HPC technology is based on the distributed network technology and computing resource,and depends on parallel computing technology of high-end computing software.Therefore,the use of HPC technology can contribute to solving the problems of high precision analysis,optimization and control for large and complex structures effectively,facilitating the improvement of building design quality.In recent years,people have witnessed the rapid development of civil engineering industry in China.With the progress of computer hardware and software technology,the common methods of finite element analysis and computing for structural design have become more and more widespread.Currently,the need for high-performance computing (HPC) technology shows increasingly urgent in structural design due to the upsurge of complex projects such as super high-rise,super-long span structures.The paper provides a state of the art review on HPC and the application in structural analysis.
