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.Hunan Provincial Meteorological Bureau has established the first remote high performance computing environment in Hunan province, thanks for the National Supercomputing Center in Changsha. In aspects of building the remote computing environment, this paper analyzes Hunan Provincial Meteorological Bureau＇s requirements for high performance computing, and its calculation requirement in meteorological service.This paper focuses on the system architecture, and the technical routes and methods on establishment of a remote computing environment with a high performance computer cluster （Tianhe-1） as the computing resource.Furthermore, give consideration to both the powerful computing capabilities of the remote computing environment and the complicated requirements for the meteorological service at provincial level, we design the corresponding system process of the remote high- performance job schedule system, and the multi-level solutions to ensure the high speed and stability of remote computing environment.Finally, we run the small-scale WRF model in the remote high performance computing environ- ment, and the results are improved obviously in calculation speed and calculation resolution, compared with that of the previously used computer cluster.
