| description | The Community Earth System Model(CESM) is a numerical model to quantitatively describe the change of climate system model, which is one of the most important research objects in the field of high-performance computing because of its huge volume of scientific computing. The load imbalance between each meteorological sub module and component of CESM makes its computing performance unsatisfactory. It is not realistic to retrieve the optimal layout manually by enumerating parameters because the diversity of available process layout schemes will lead to a huge amount of retrieval. In order to solve this problem, this paper proposed and implemented a retrieval strategy based on the matrix-nesting idea of load balancing optimization scheme to help the process layout and intervenes in the screening work based on the parallel requirements of the original model. Finally, the experiment proved that the optimal layout obtained by this search strategy search had a performance improvement of 47.3% compared with the default layout and achieved an acceleration ratio of 1.419 on 5 nodes. |
