摘要：
During parallel multigrid computations, the Jocobi components along pseudoboundaries in the block by block relaxations operator become the main source todecrease the numerical efficiency of multigrid. We investigate these decrements indetail for constant coefficients Symmetric Positive Definite elliptic model problemsby error character1stic functions in this paper, then some strategies are gained. Atlast, advection-diffusion problems are addressed.
