【摘要】 为快速求解大型拟块三对角方程组，根据超立方多处理机系统的结构特点、通讯特征，结合求解问题本身的特点，给出了一种快速算法，并分析了该算法的运行时间复杂性．在并行虚拟环境（ＰＶＭ）下做了数值试验，求出了在多台工作站上的运行时间及加速比，并与共享内存多处理机上运行结果进行比较，证明该算法在超立方上运行速度较快更多还原

【Abstract】 According to the topological property of hypercube and the hallmark of the problem to be solved,a fast algorithm to solve large quasi-block triangular equationsis presented.Its time complexity and numerical experiment under PVM environment are conducted.The operational time and speedup on a few workstations are gotten.Compared with the shared memory multiprocess,the algorithm runs faster on hypercube.更多还原
