摘要
针对目前WRF模式迁移中存在的问题,提出具体迁移部署的方法。随后通过对美国东部地区降雨模拟,给出WRF模式在Intel X86和ARM架构上的计算性能的差异,通过NCL方法计算了结果的准确性。实验结果表明,WRF模式可被完整地迁移到ARM架构的超级计算机上。仿真结果显示,在并行运算下,WRF模式在ARM架构超算集群上耗时更短,且单节点运算中ARM可有效提高并行运算效率,具有一定的使用价值,为研究者提供参考。
Aiming at the problems existing in WRF migration,a concrete method of migration and deployment is proposed.Subsequently,by simulating the rainfall in the eastern region of the United States,the difference of computing performance of WRF on Intel X86 and ARM architecture is given,and the accuracy of the results is also calculated by the NCL method.The experimental results show that WRF can be completely migrated to supercomputer on ARM architecture.The simulation results show that WRF takes less time in the supercomputer cluster on ARM architecture under parallel operation,and ARM can effectively improve the efficiency of parallel operation in the single-node operation,which has certain application value and provides a reference for researchers.
