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.

In order to quickly solve the large quasi-block three-diagonal equation system, a fast algorithm is proposed according to the structural characteristics and communication characteristics of the hypercube multiprocessor system, combined with the characteristics of the solution problem itself, and the running time complexity of the algorithm is analyzed. Numerical experiments were carried out in parallel virtual environment (PVM) to find the running time and speedup ratio on multiple workstations. The results of the shared memory multiprocessor are compared, which proves that the algorithm runs faster on the hypercube.
