| Abstract: | From the viewpoint of distributed memory and parallel computing, the overlapping additive methods, such as AS (classical additive Shcwarz), RAS (restricted additive Schwarz) and PAS (parallel additive Schwarz) were inspected again. And a new kind of additive method, called "Distributed Additive Schwarz Method" (DAS), was proposed and analyzed. Numerical experiments showed that DAS was more efficient than other additive methods in terms of iteration number and iteration time. |
| Keywords: | parallel computing domain decomposition additive Schwarz distributed memory |
