【摘要】：湖南省气象局依托国家超级计算长沙中心,建立了我省第一个远程高性能计算终端用户.针对远程环境的搭建,首先分析了湖南省气象局在高性能计算方面的需求,然后从省级气象部门业务计算需求出发,重点阐述了以高性能计算机集群"天河一号"为计算资源的远程计算环境的系统架构以及主要技术路线与方法.考虑到远程高性能强大的计算能力和省级气象部门作业提交的复杂需求,又进一步设计了湖南省远程高性能任务调度的系统流程以及保障远程计算环境高速稳定的多层面方案.最后也给出了高分辨率中小尺度WRF模式在该环境下运行的实际情况,计算速度改善非常明显.
[Abstract]:Relying on the national super-computing Changsha Center, Hunan Meteorological Bureau established the first long-range high-performance computing end user in our province. Aiming at the construction of remote environment, this paper first analyzes the demand of Hunan Meteorological Bureau for high performance calculation, and then starts from the operational requirement of provincial meteorological department. The system architecture, main technical route and method of remote computing environment with high performance computer cluster "Tianhe No. 1" as computing resource are expounded in this paper. Considering the powerful computing power of remote and high performance and the complex requirement of provincial meteorological department job submission, the system flow of remote high performance task scheduling in Hunan Province and the multi-level scheme to guarantee the high speed and stability of remote computing environment are further designed. Finally, the actual operation of the high resolution mesoscale WRF model in this environment is also given, and the computational speed is greatly improved.
