    Abstract
  • To improve the parallelism degree and execution efficiency of a torpedo guidance simulation system, we introduced parallel programming standard OpenMP and multi-core processors into the simulation system. Software framework of the simulation system was designed using object-oriented programming, and the characteristics and parallel relationship of each task were analyzed. Furthermore, OpenMP was used for parallel processing, and the simulation system operated on Silicon Graphicsn (SGI) workstation with eight-core processors. Simulation results show that the time-consumption on average in single computation step can be reduced to 7~8 ms. Compared with the other torpedo simulation system, our method significantly reduces the computing time, and effectively improves the implementation efficiency of the simulation system.
