Research on Parallel Progress Method of Weather Radar Data Mosaic
摘要
Abstract
Weather radar mosaic parallel processing purpose is to meet the demand of real-time service,usually serial method cannot achieve in radar running cycle.Using high performance server of shared memory multiprocessor,develop the parallel computing system of high frequency real-time weather radar data processing.According to single weather radar processing and multi-radar mosaic characteristics,put forward the two stage parallel method of the process level and thread level of fine particle size OpenMP shared memory programming.Give a reasonable derived thread size,put forward the shared memory file method to improve the program execution efficiency.The experimental results show that,the use of two stage parallel calculation method to the national weather radar can satisfy the requirement of real-time processing.Use of parallel process is important for real-time system.关键词
