基于四阶龙格-库塔法的多弹道并行计算研究
Research on Parallel Calculation of Multi-ballstic Based on Fourth-order Runge-Kutta Method
摘要
Abstract
Ballistic calculation is a type of typical computing intensive problem,which plays a vital role in aircraft design and trajectory planning.The solution to this problem usually involves a large amount of calculation and time-consuming problems.In order to realize the acceleration of ballistic calculation,this paper uses multi-threaded parallel computing technology to design a multi-ballistic acceleration calculation architecture based on the fourth-order Runge-Kutta method,and maps the multi-ballistic calculation to different threads through task division.The threads are then scheduled to the processor cores for load balancing.Experiments are designed to analyze the influences of key factors in multi-ballistic calculation,and the simulation results show using multi-ballistic parallel acceleration architecture can effectively improve the time efficiency of ballistic calculation and the computing efficiency for the differential equations with high precision and high computational complexity.The developed architecture can also be used to accelerate the solving procedure for the differential equation problems.关键词
