摘　　要：以MPI作为编程环境,实现了反应扩散方程的并行计算。通过比较在单核和双核CPU上的运行时间,可以看出:双核CPU可以大大提高并行程序的运行效率。并且,当并行程序中的进程数为CPU内核数的整数倍时,并行程序运行效率最高。The parallel computing of reaction - diffusion equation has been realized based on MPI environment. Compared the run time of mono - core computer with that of dual - core computer, we could see that the dual - core computer could improve the efficiency of parallel program greatly. Furthermore, when the number of process of the parallel program is the times of the core number of CPU, the efficiency of the parallel program is the best.
