ABSTRACT
A new approach to interpretation of seismic tomography data is proposed. The model based inversion is usually limited for velocity model calculation. However, uncertainties of these data within geological interpretation led us to developing a compositional based inversion algorithm. In this study joint seismic and gravity data inversion methodology are described. Parallel computing algorithm requires large datasets. The purpose of our paralleled tomography is to deliver better performance utilizing all CPU’s performance as well as using installed in PC GPU. Running CUDA Kernels will have a large impact on processing time and also may affect in solving much more difficult models at the same amount of time comparing to CPU. This tomography approach could be useful both in seismological and shallower seismic investigations.
