ALGORITHM AND PROGRAMM CODES FOR 2D SEISMIC FIELD SIMULATION AND COMPUTATION, AND THEIR PRACTICAL APPLICATION
An algorithm for simulation of elastic wave propagation in 2D inhomogeneous isotropic elastic media is presented. The parallel realization of algorithm to perform computations on high-performance computing systems with different architectures is developed and proposed. Program codes to perform calculations on the basis of finite-difference method of fourth order respect to space were developed. The presented technology of mathematical modeling with usage of MPI and CUDA is used to perform computations for long distance realistic model for seismic profile of 400 km of size. The obtained new synthetic data depicting the structure of seismic filed for the Baikal rift zone are presented.
