数值天气预报后处理系统的作业级并行实现

Job-level parallel implementation method of numerical weather prediction post-processing system

对于具体问题采取何种并行方法,达到好的并行效果,是在并行化工作中需要考虑的。通过对数值天气预报模式T511后处理系统的特点分析,结合其运行的计算机环境特点,提出了一种"作业级的并行实现"方法,减少T511后处理系统所需的计算墙钟时间。该方法具有并行化工作量小、易于实现、并行效果好等特点。

During parallelizing a program, a specific parallelize method must be chosen to obtain a good parallel effect. Through analyzing the features of numerical weather prediction model T511 post-processing system and considering its characters of computing environments, this paper proposed a job-level parallel method which can decrease the wall-time when running pest-processing system. This method has the benefits of small workload for parallelzing, easy realization, and ideal parallel efficiency.
