Efficiency of Linux Clusters in Multi-Component Elastic Wave Field Modeling in Anisotropic Media

In the paper the effectiveness analysis of the seismic waves modeling in anisotropic media are discussed. The computations were performed on 31 nodes PC cluster working under Linux Fedora operating system. The efficiency analysis of the computation time for a typical seismic set-up consisted of 10 shoot points was made. The considerations are made for a weak anisotropy geological medium so the Thomsen parameters could be used. The results of modeling time for acoustic, elastic, elastic with dumping, anisotropic and anisotropic with flux corrected transport algorithms are presented. Not only different algorithms abut also different cluster nodes configurations, different switches and even different Linux kernels ware compared in the presented analysis. The results clearly shows that inexpensive PC clusters are efficient tools for wave propagation modeling in the scale necessary for engineering applications.
