| Abstract: |
| To apply the Generalized Minimum Residual algorithm to the solution of large-scale BEM systems, the precondition technique and he re-orthogonalization technique are adopted. Based on these practical techniques adopted above and the good parallelism of iterative algorithm, the parallelization technique is also studied under the networked PC cluster environment. The numerical tests and analysis show that all these techniques are useful and of great importance for accelerating the speed of solution and enlarging the scale of the problem. |
