Simulation and reconstruction for 3D elastic wave using multi-GPU and CUDA-aware MPI

3D finite-difference time-domain numerical simulation and reconstruction based on the domain decomposition technique are essential parts of high-performance computation for reverse-time migration and full-waveform inversion. However, the low GPU utilization in computing for small-sized models and th...
