WRF模式在LINUX集群系统的并行计算与评测
Parallel Computing and Evaluation of WRF Model on LINUX Cluster System
摘要
Abstract
WRF meteorological model is a high-perfoniiaiice parallel computing,geiierally require mainframe computing and parallel processing. This system will be built on the 32 WRF Core Xeon cluster system. One WRF patients was selected to evaluate the system performance of the total computation time,parallel efficiency and acceleration rate. The results showed that: with the gradual increase in the number of processors to 16,the total lime decreases monotonically with the number of processors. From 16 to 26,the overall trend of the total time is decreasing,but did not change significantly. From 26 to 32,the overall trend erf the total time is increasing. The experimental cluster system has good parallel efficiency and acceleration rale. When the processor is 26, the belter parallel performance can be a-chieved, maximum acceleration rate is 12.5,and parallel efficiency is 48%.关键词
