20. warning system must be established. Nowadays, there is nowarning system thatis both accurate and fast
enough togenerate thewarning in time, thus false alarms are common. Soonpeople will ignore the
warning, and we may face another tragedy.
There is a program named TUNAMI which can accurately calculate the water level and thespeed
of tidal wave given initial parameter, butthis program is very slow due toa lot of calculation. The parallel
tsunami simulation program will be theparallel version of TUNAMI, applying bothfunctional and
domain decompositions. This program will bemuch faster than theoriginal program and will be able to be
used in real-time warning system.
