摘要
基于虚拟化与并行化技术,对现有"华龙一号"数字化设计验证平台架构进行升级改造,将仿真环境部署到资源虚拟化的私有云平台中,对仿真支撑平台实施基于网络层RDMA协议远程取址方式改造,通过使用物理层Infini Band网卡和交换机组建高速网络,将高精度仿真模型程序部署于高性能计算节点(HPC),达到基于高性能计算的跨机分布式实时并行运算目标。经过验证场景配置与仿真运行测试结果表明:升级后的配置是可行的,能够提升信息化运维管理,集约化计算机资源,满足不同的验证任务与验证场景配置需求。
Based on virtualization and parallelization technology,the architecture design of the"Hualong one"nuclear power plant digital design verification platform is upgraded.The simulation system is deployed to the virtual private cloud platform.The remote access mode is modified based on network layer RDMA protocol,and a high-speed network is built by using InfiniBand switching technology.Highprecision simulating models are deployed on the high-performance computing node(HPC)to achieve the goal of cross machine distributed real-time parallel operation.After configuration performance test and simulation performance test performed,it shows that the upgraded architecture is feasible,which benefits for the operation and maintenance efficiency,intensifies computer resources,and meets the configuration requirements of different verification tasks and scenarios.
