Parallel Performance Analysis of WRF 3D-Variational Assimilation
Xiaoqian Zhu · Computer Engineering and Science · 2007
Performance analysis of parallel applications plays an important role in the implementation and optimization of scientific computing. It is used to show the behavior of parallel applications and high-performance computers. In this paper, the principle and parallel strategy of WRF 3d-variational assimilation are introduced. Based on the performance analysis tool TAU,the parallel application of WRF 3d variational assimilation is quantitatively analyzed. The hotspots and bottlenecks are located and the related optimization methods are proposed.
