A software package designed for multiprocessor systems of cluster architecture is used to simulate wave processes in geomedia. The applied computational algorithm for solving a two-dimensional axisymmetric problem is based on the method of two-cyclic splitting with respect to spatial variables. With the use of the developed computational technology the amplitude-frequency characteristics and seismic efficiency for different types of pulse loading are obtained. The artificial dissipation of energy caused by the properties of the applied finite difference scheme is taken into account. Richardson extrapolation is applied to refine the computational method of seismic efficiency.
