A Performance Tool for Earth System Models Development

摘要：

　　We present s performance tool for Earth system models development to aid in analyzing the performance of the climate modeling applications.It is difficult for existing tools to handle with the complex,coupled structure and the long execution time of models.Our performance tool implements rapid analysis based on statisticai sampling and grouping aggregation the calling relationship and the actual computing resource consumption excluding waiting losses.Using this tool,we study an ocean model POP in short-term sampling and analyze its scaling bottleneek and acceleration trend.The measuring results of its entire execution prove our predictions on the sealing efficiencies.
