Abstract: In this research, we describe applications of the LexADV_EMPS solver framework to tsunami run-up and inundation simulations on the Fujitsu FX100. To achieve high performance of particle-based simulations, the LexADV_EMPS framework supports hierarchical domain decomposition, halo exchange pattern of communication, and dynamic load balancing on the distributed-memory parallel computers. By using our framework, we have successfully performed large-scale numerical simulations of tsunami run-up and inundation with hundreds of millions of particles for the purpose of the tsunami impact assessment.
