对流扩散方程的精细积分并行算法

讨论了一维扩散方程的全域精细积分和子域精细积分的并行算法，给出了对流扩散方法的子域精细积分并行算法。子域精细积分考虑了细积分法高精度的特点，又避免了全域积分的大矩阵运算；春精度优于单点精织积分法，同时子域精细积分很容易实行并行计算。算例表明了精细积分并行算法有良好的并行加速比和效率。

Parallel algorithms of precise integration of convection diffusion equations

? This paper presents the parallel algorithms of precise integration methods. The subdomain parallel algorithms of precise integration of convection diffusion equations are given. The methods take advantage of the high precision of precise integration methods, and they also avoid a large amount of matrices calculation of whole domain methods. The precision of the methods is better than that of the single point integration. Numerical examples show that the parallel algorithms have high speedup and efficiency.
