Abstract
Seismic wave forward provides theory basis and theoretical data for inversion method in the process of oil exploration,and can test the effectiveness of inversion method,it is very important to reflection seismology.In this paper,we complete the design of 2-level MPI parallel and multi-core thread parallel of 3D acoustic wave equation forward algorithm through analysing it and in combination with the characteristics of a multi-core platform,and make the correlated optimisation as well.Experimental results show that the multi-level heterogeneous parallel method of 3D acoustic wave equation forward has preferable multi-core parallel acceleration effect and good MPI scalable performance.关键词
