为了在高性能计算机上求解广义鞍点问题,对于合适的系数矩阵,本文提出混合并行迭代法及其加速形式.并详细讨论了新方法的收敛性.
A class of parallel hybrid iterative methods and its accelerated overrelaxation variant are established for solving the generalized saddle-point problems. The new method converges to the so- lution under suitable restrictions on coefficient matrices.
