PERANCANGAN KOMPUTASI PARALEL MENGGUNAKAN NVIDIA CUDA UNTUK PEMODELAN 2D TSUNAMI DENGAN METODE LATTICE BOLTZMANN

Abstract

Tsunami is a natural occurrence that affected the existence of activities that occur on the seafloor, these activities can be a sea earthquakes, erupting volcanoes, or a meteor hit the ocean, landslides on the seafloor. Tsunami Aceh is one of the greatest disasters of the 21st century, beginning with the 9.1 magnitude earthquake in Aceh resulted in deaths reach 200 thousand inhabitants, not included in other areas such as Thailand, Sri Lanka, India, Maldives, and the east coast of Africa. Given the tsunami hazard in this study made a modeling design using paralelel computing for modeling tsunami in Aceh, using NVIDIA CUDA and lattice Boltzmann method D2Q9. This model is expected to help to determine the direction of propagation of the tsunami wave.
