Jacobi-type Gauss-Seidel Smoother with Error Compensation for Parallel Multigrid
parallel multigrid parallel Gauss-Seidel JGS JGSEC
2012/8/10
Smoother is the most important component of parallel multigrid methods, however,
the widely used Gauss-Seidel smoother is difficult to be parallelized. This paper
proposes a new parallel smoother, J...
