Domain decomposition and multilevel methods
Domain decomposition methods consists in decomposing the original mathematical problem into a collection of smaller (and computationally cheaper) subproblems, each of which can be solved independently. The divide-and-conquer philosophy at the basis of iterative domain decomposition methods has been proved to be the ideal paradigm for large-scale simulation on massively parallel computers.

Multigrid and multilevel methods employs a hierarchy of discretizations to solve differential problems. The main idea at the basis of these techniques is to accelerate the convergence of basic iterative solvers employing (recursively) a global coarse correction. For a certain class of problems, multigrid methods are among the fastest solution techniques known today since they feature optimal computational complexity and scaling properties.
