| Zusammenfassung: | Abstract: "Row projection algorithms for solving nonsymmetric linear systems are theoretically robust, converging for systems with indefinite symmetric parts and arbitrarily distributed eigenvalues. Slow convergence, however, has prevented their widespread use. This paper shows that a domain decomposition approach gives row projections methods that allow parallelism in the computations. The level of concurrency and size of the created subtasks can be chosen to suit the target machine, and the resulting algorithms have advantages over standard domain decomposition methods." |
