Optimization of Weather Model

Abstract

Weather Research and Forecasting (WRF) is a primitive application of High Performance Computing (HPC). Research on WRF being able to utilize the computation efficacy. Today’s HPC has so much research going on. There are various parallel Programming Technologies used to achieve the speedup.The Stencil Computation is used by WRF model for regional grid computation and it’s a difficult to compute because it depends on their entire neighbor’s. In this paper propped method to achieve the stencil Computation for parallel approach like open MP then apply Vectorization flags O3 and then last Vectorization. Analysis of all the results to how its speedup and achieved Optimized code for Stencil Computation.
