Abstract
In analyzing the quality of seismic signal, the fundamental mathematical operation is the convolution of signal with basic signal. Analyses carried out in the field need solutions that can be executed by a single machine. Meanwhile the size of processed data from land seismic surveys is in order of tens of terabytes. In this article the efficient computation of convolution on GPU cores is proposed. We state that this approach if faster than even using parallel programming on CPU. It will be shown how big performance gain was achieved when using a graphic card that is several times less expensive than used CPU.
