Three dimensional wave propagation model of parabolic approximation type is widely used in exploring the ocean. For this application, FOR3D model is one of the mostly used models, for it takes the azimuthal coupling into consideration and the result gains a better precision. When the precision requirement is high, large scale computation task would be faced, which cannot be solved only in one computer or constrained time. In this paper, we propose a parallel method to decompose the computation task, which divide the original computation into small size. Then each processor get one piece of task and run the FOR3D independently. Our method was implemented on Windows Azure and the result shows that we almost gain a linear speed-up.

Computer games, such as chess, have recently become an important research topic in the field of computation intelligence. Monto Carlo massive searching is very successful in the game of GO as it has a huge intractable search space and no good partial evaluation heuristics. Imperfect information games also have intractable properties, such as large scale search space, less heuristics, and unknown state information. Monte Carlo search is therefore effective to make computer players for the imperfect information game. There is always a time limit for using computational intelligence in actual applications. Such constraints require parallel processing to be speed up the Monte Carlo simulations. We introduce a parallel Monte Carlo searching method for imperfect information card game Daihinmin, a familiar card game in Japan. Computer Daihinmin competitions have been held since 2006. We present two kinds of parallelization algorithms for Monte Carlo computer Daihinmin players.
