An overview of multilevel methods with aggressive coarsening and massive polynomial smoothing
Electronic transactions on numerical analysis, Tome 44 (2015), pp. 401-442
We review our two-level and multilevel methods with aggressive coarsening and polynomial smoothing. These methods can be seen as a less expensive and more flexible (in the multilevel case) alternative to domain decomposition methods. The polynomial smoothers employed by the reviewed methods consist of a sequence of Richardson iterations and can be performed using up to $n$ processors, where $n$ is the size of the considered matrix, thereby allowing for a higher level of parallelism than domain decomposition methods.
