| Abstract: |
| In this paper,for solving the cyclic tri-diagonal equations problem appearing in engineering computing,with the use of Sherman-Morrison function,the cyclic tri-diagonal equations are transformed into two tri-diagonal equations,also combined with Divide And Conquer(DAC) method inplements parallel computing.Then,under parallel analyzing the cyclic tri-diagonal equations,the parallel programs with the portable Message Passing Interface(MPI) in the PC-cluster system are given.The computing results show that this method can get numerical stability and good parallel performance when it was applied to solve for cyclic tri-diagonal equations. |
