The results of numerical 2D and 3D simulations of highfrequency induction logging on a GPU platform are presentid. The conjugate A-orthogonal conjugate residual method with our full parallel preconditioner derived from the Hotelling-Schulz algorithm is used. Comparative analysis of the calculation time of the GPU implementation and CPU implementation is done. Numerical experiments show that the speed-up, obtained on GPU as compared to the CPU implementation for the 3D problems, is as great as 15-20 fold.
