摘要: |
本文给出块对角主元法的并行计算,证明了用这种方法分解矩阵是稳定的。同时编制了向量 FORTRAN程序,在向量机上进行了数值试验。计算结果表明:当 n>100时,向量计算比标量计算快10倍以上。 |

Paral1el Computation of the Block Diagonal Pivoting Method |
Li Xiaomei, He Xinfang |
Abstract: |
In this paper a parallel algorithm of the block diagonal pivoting method is given. The method of decomposing symmetric matrice is shown to be stab1e and the method is implemented on parallel computer. Computing result shows the parallel algorithm is ten times faster than the seria1 algorithm when n is greater than 100. |
