A Case Study of Urgent Computing on SX-ACE: Design and Development of a Real-Time Tsunami Inundation Analysis System for Disaster Prevention and Mitigation

In 2011, a huge earthquake named Great East-Japan Earthquake gave a serious damage in Japan, especially due to Tsunami inundation caused by the earthquake. After this terrible natural disaster, there is a growing concern about future big earthquakes and Tsunami disasters in Japan, and a demand for their prevention and mitigation is increasing. To react this high demand, we are designing and developing a realtime Tsunami inundation analysis system on a brand-new vector supercomputer SX-ACE installed at Tohoku University as a case study of urgent computing for earthquake and Tsunami disasters. In this article, we will present an overview of the system and its performance in the Nankai trough earthquake case.
