摘要
从当前水工数值仿真中面临的问题入手,总结了水工数值仿真中有限元并行计算的3个策略:方程组并行求解、区域分解、EBE方法;比较了实现并行计算采用PC网络机群、高性能计算集群、GPU通用计算的优缺点,指出了GPU集群将成为水工数值计算的新的硬件基础.并着重阐述了高性能计算在高拱坝地震损伤计算、拱坝-地基系统的有限元计算、闸门结构分析和随机有限元等水工数值仿真问题中的应用.最后探讨了云计算在水工数值仿真中的应用,并指出云计算将成为水工数值仿真,尤其是水工实时监测与反馈分析新的发展方向.
In recent years, the high performance computing （HPC） has been applied to hydraulic structure engineering numerical simulation. Based on the applied situation,this paper summarizes the finite element parallel computation in the hydraulic structure numerical simulation into three strategies., parallel solving of equations, domain decomposition method, element-by-element method. The paper compares and lists the advantages and disadvantages of PC network fleed, high-performance computing cluster and the gener al-purpose computing on graphics processing units （GPGPU）, which are the hardware base of HPC. Even tually, GPUs are pointed to become new hardware foundation of numerical calculation. And then the paper emphatically elaborates the high performance computing in damage prediction of high arch dams subjected to earthquakes, finite element calculation of arch dam-foundation system, gate structure analysis and sto- chastic finite element in the hydraulic structure numerical simulation. Finally this paper discusses tile appli- cation of cloud computing in the hydraulic structure numerical simulation, and points out that cloud compu- ting will become the new development direction in hydraulic structure numerical simulation, especially hy draulic structure real-time monitoring and feedback analysis.
