Incremental mapping for solution-adaptive multigrid hierarchies
The full multigrid method uses a hierarchy of successively finer grids. In a solution-adaptive grid hierarchy each grid is obtained by adaptive refinement of the grid on the previous level. On a distributed memory multiprocessor, each grid level must be partitioned and mapped so as to minimize the multigrid cycle execution time. In this report, several grid partitioning and load (re)mapping strategies that deal with this problem are compared. The influence of the type of multigrid cycle is examined. Results obtained on an iPSC hypercube are reported.<>
