Abstract :
We use Finite Volume Method based on Shallow-water equation to simulate the Tohoku 2011 tsunami and parallelize the code using OpenMP. With the parallelization, we achieved over 80% of the potential speed-up on multi-core system. Using adaptive mesh refinement (AMR) to obtain high resolution result in important region, and the highest resolution near Sendai airport and Fukushima nuclear power plants is about 20 meters.
