Parallel Algorithm based on the multithread technique for pseudospectal modeling of seismic wave

XIE Gui-sheng, LIU Hong, ZHAO Lian-gong (Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029)  
The modeling of 3D seismic wavefiled is often involved in mass data storage and requires huge amounts of computer memory and computation time. Even when using current powerful computers, it is still computationally very intensive. To overcome this, the parallel algorithm for 3D wavefiled modeling based on concurrent use of a number of processor by the multithread technique has developed. To illustrate the feasibility of our parallel algorithm, the two examples for pseudospectral modeling of seismic wave are given: 2D acoustic and 3D elastic anisotropy modeling of wave propagation.
