  abstract = {{N}umerical simulation of tsunami propagation in large basin across the ocean demands significantly high computational capability in terms of {CPU} time and memory allocation. {D}ue to this limitation, the use of sequential codes in a single scientific workstation is possible only for small-scale tsunami problem. {T}o overcome this difficulty, a parallel {B}oussinesq wave model is developed based on the original {FUNWAVE} sequential model for efficient simulation of long wave propagation, coastal inundation and runup. {T}he numerical resolution is decomposed into small sub-domains using domain decomposition technique for each processor to perform the calculations. {T}he wave information is exchanged between processors via message passing interface ({MPI}). {W}e show the effectiveness of this parallel code on distributed- and shared-memory computer clusters in simulating two tsunami events: the 2004 {I}ndian {O}cean and the 1999 {V}anuatu tsunamis. {C}ommunication in the overlapping domains and load balancing in the partitioned domains are considered to ensure the efficiency of this method. {I}t is found that the performance of the parallel model for both large- and small-scale tsunami problems is very satisfactory. {F}inally, the parallel model is applied to a spatial hierarchical grids methodology for a location-specific numerical simulation. {G}rid sensitivity and improved simulation results for runups along {P}hang {N}ga coastline from {T}akua {T}hung to {K}hao {L}ak are presented.},
