บทคัดย่อ Tsunami is one of the most serious disasters. To prevent
from the loss, an effective warning system must be established.
Nowadays, there is no warning system that is both accurate and fast
enough to generate the warning in time, thus false alarms are common.
Soon people will ignore the warning, and we may face another tragedy.
There is a program named TUNAMI which can accurately
calculate the water level and the speed of tidal wave given initial
parameter, but this program is very slow due to a lot of calculation.
The parallel tsunami simulation program will be the parallel version of
TUNAMI, applying both functional and domain decompositions. This
program will be much faster than the original program and will be able
to be used in real-time warning system.
