| Abstract: | With the developments of theory and technology of underwater acoustics, an efficient method for sound field calculation is very important. The emergence and popularity of PC with multi-core technology will give us a great opportunity to improve the efficiency. The parallel programming of the parabolic equation model RAM is implemented in this paper on the basis of the OpenMP, a Portable Shared Memory Parallel Programming. The numerical simulation demonstrates that the parallel programming of RAM achieves high efficiency. |
