Outline of Final Research Achievements

We have developed a method where GPU and CPU effectively cooperate to achieve large-scale computation under small size GPU cluster, by using CPU side of memory from GPU. Proposed method realized fluid simulation using higher resolution grid while minimizing data communication delay between GPU and CPU. Experiments showed our implementation of multiphase thermal flow computation could handle various thermal flow simulations under many different kinds of situation. We have introduced the photon mapping method for advanced distributed visualization, and also for highly accurate thermal radiation computation.
