摘要
预处理技术在改善系数矩阵条件数和保证收敛的问题上起到了举足轻重的作用。文中将Java多线程技术与SSOR-PCG算法相结合,设计并实现了一个可交互的并行求解器,为用户的求解过程提供了许多便利。通过算例表明,二者的有机结合可以有效地提高运算效率,同时也可看出运算速度与线程数量并不成正比。
The pretreatment technology is very important to improve the condition number of coefficient matrix and ensure its con- vergence problem. In this paper, an interactive parallel solver is designed; it will offer many convenient for the user. The technology of this solver is Java multi-thread and SSOR pretreatment iterative. Numerical example shows that the efficiency of operation can be im- proved effectively by using these technologies, but the computing speed is not proportional to the number of threads.
