TESLA GPUs versus MPI with OpenMP for the Forward Modeling of Gravity and Gravity Gradient of Large Prisms Ensemble

<table>Speed-up of the behavior by increasing the number of processing cards in double and single precision. The number of blocks is 14 and the number of threads per block is 512 in every card, the optimal setup found for one single card. </table>
