Abstract

The finite difference time domain code TEMDDD was modified for the 3D forward modeling of marine CSEM data.
After changes in the code, which make it possible to create model geometries typically encountered in marine CSEM
experiments, parts of the code have been parallelized using massive parallelization on graphic cards.
Parts of the singular value decomposition, which is the most time consuming part of the code, have been successfully
ported with massive speed-ups (8-12x faster) observed as compared to the standard code. The full parallelization of the code is still work in progress.
