摘要:

用改进的JGS迭代方法求解抛物型方程, 构造了一种新的并行计算格式, 并证明了新算法是绝对稳定的、 显式的, 截断误差达到O(τ+h2). 数值实验结果与理论分析相符.

关键词: 并行计算, 差分方程, JGS迭代法, 稳定性, 截断误差

Abstract:

The improved JGS iterative method was used to solve parabolic equations, and a new parallel method was constructed. We prove that this method is absolutely stable and explicit, and its truncation error reaches O(τ+h2). The  numerical experimentation agrees with the theory analysis.

Key words: parallel computation, differential equation; , JGS iterative methods, stability, truncation error
