为了得到循环GMRES算法的高效实现方法,将循环GMRES算法的两个主要过程看作子系统,并考察子系统的不同耦合方式对整体系统的影响。给出了循环GMRES算法的弱耦合向量化实现。实验表明,在向量编程环境中循环GMRES算法的弱耦合实现效率更高,编程也更容易。

To obtain the efficient method of loop GMRES algorithm, the two main procedures of loop GMRES algo- rithm were regarded as two subsystems, and the influences of different coupling patterns of the subsystems on the whole system were observed. In particular, a weak-coupling vector implementation for loop GMRES was given. Ex- perimental results show that the weak-coupling implementation is more efficient than the original implementation under the environment with the merit of easier programming.
