Example codes demonstrating the use of HYPRE using other XSDK packages (SuperLU_DIST).

The ex5_superlu_dist.c example demonstrates HYPRE's Linear-Algebraic (IJ) interface for solving the 2-D Laplacian problem with zero boundary conditions on an n x n grid using various solvers (AMG, PCG, PCG with AMG preconditioner, Flexible GMRES with AMG preconditioner) from HYPRE with the option to use a distributed LU factorization from SuperLU_DIST as the coarse level solver in BoomerAMG. The number of unknowns is N=n^2. The standard 5-point stencil is used, and we solve for the interior nodes only.
