| Abstract (English) |
We describe block versions of Cimmino and SSOR algorithms for solving general sparse systems. We consider their acce1eration using conjugate gradients and the choice of a preconditioner for both the methods. The effect of the block partitioning is a1so discussed. Experiments on an Alliant FX/80 indicate the effectiveness of the two methods on quite general systems and show the differences between them. | |
