Computational Fluid Dynamics is an important tool to design aircraft components. FaSTAR is one of the most recent CFD program package with various solvers and automatic generation of grid data. However, FaSTAR is inefficient to be executed in parallel machines because of its irregular data structure. For example, calculation using compound assignment operators suffers enormous pipeline hazards caused by consectively accessing same data. Using FLOPS-2D, one of reconfigurable system constructed of FPGAs, we would like to improve the problems caused by memory access, and accelerate execution of FaSTAR. In the first step of whe work, an Out-Of-Order system was proposed. In this work, we applied this system to various algorithms, and evaluated its performance. Consequently, with FPGAs, the selected algorithms runned 3.21 times as fast as software execution on Intel Core2Duo(2.66GHz) in all. |
