| Outline of Final Research Achievements |
In this project, we aim to develop efficient algorithms for solving large linear systems and apply to some real applications. In order to achieve these purposes, we developed iterative-type preconditioning techniques which have high speed, high stability and high parallel efficiency. We also provided parameters optimization techniques for improving convenience of the proposed preconditioning techniques.
The proposed preconditioning techniques and their parameter optimization techniques were applied to supernova simulation. The proposed techniques made it possible to solve efficiently difficult problems for traditional techniques. Then, the proposed techniques adopted to a supernova simulation code and are beginning to make achievements.
