Parallelization of normal mode-WKBZ computation for ocean acoustic field

摘要

The real-world applications of ocean acoustic field computations present serious computational requirements for high performance computing technologies. At the same time, more and more engineers and researchers are using parallel processing technologies to improve computational performance using emerging parallel hardware architectures. In this paper, we introduce latest parallel computing technologies to ocean acoustics computation, after analyzing parallel computing requirements of computational ocean acoustics models, especially Normal Model (NM) method. Then, parallel algorithm of NM-WKBZ Computation is put forward. All experimental results on Multi-core, Cluster and GPU systems are given respectively. At last, the cost performances of different parallel systems for ocean acoustic computation are also discussed.
