Abstract
Summary
We developed a 3D Laplace-domain Full waveform inversion (FWI) program using Compute Unified Device Architecture (CUDA). We adopted a preconditioned conjugate gradient (PCG) matrix solver instead of a direct solver to reduce the memory required for computing. To accelerate the performance, we parallelized the PCG solver using CUDA programming. We confirmed the validity of this algorithm by applying it to the SEG/EAGE 3D salt-dome model and 3D real wide-azimuth dataset. By comparing the results using a GPU and CPUs, we concluded that a single GPU can be efficiently applied to the 3D Laplace-domain inversion.
