摘要
为在现有硬件计算条件下缩短弹道与诸元计算时间,提高武器的快速反应能力,通过Intel Vtune(程序性能分析器)对弹道与诸元计算软件进行深入分析,并结合弹道与诸元计算模型的特点,研究确认了经典的弹道与诸元计算模型中的热点和具有良好并行性的部分,采用线程池技术对弹道与诸元计算软件进行并行改进和实现,经过仿真验证,证明该算法能有效提高弹道计算的速度。
To reduce the time spent on trajectory and data calculation and improve the quick reaction of weapon,the trajectory and data calculation software was analyzed via Intel Vtune.Combined with the characteristic of trajectory and data calculation model,the hotspot and the part with good parallelizability in the classical model of trajectory and data calculation were studied.The trajectory and data calculation software was improved and realized through the thread pool.The simulation proved this arithmetic can effectively improve the speed of trajectory calculation.
