时域有限差分算法的并行实现

随着许多工程领域的计算量在不断加大，就提出了并行计算技术问题。而在目前高性能计算机系统中，最广泛使用的一种标准是MPI，它已成为一种并行程序的标准。MPI的理念就是需要将问题的并行求解算法转化为特定的适合并行计算模型的并行算法。麦克斯韦旋度方程的数值分析有多种方法，但其中的时域有限差分法是一种较好的方法。在用时域有限差分法进行数值计算时，需要进行大量的数据采集与计算。在这里，采用并行的方法给予实现，提高计算速度。

Finite Difference Method by Parallel Computing

Along with the amount of calculation of many engineerings increases,the technology of parallel computing becomes requisite.MPI,which is a standard,is the most extensive usage in high performance computing system.The MPI principle is to transform the problem of proceeding together to beg to solve the calculating way into particularly keeping with to proceed together to compute the model abreast calculating way.There are many ways to analysis and computation of Mikthw's two rotations equation,finite difference method is the most one while using the finite difference method,a flood of data need be collected and computed.Therefore,we use paralleled computing method to make it true,and improve computing.
