AMGCL is a header-only C++ library for solving large sparse linear systems with

algebraic multigrid (AMG) method. AMG is one of the most effective iterative

methods for solution of equation systems arising, for example, from

discretizing PDEs on unstructured grids. The method can be used as a black-box

solver for various computational problems, since it does not require any

information about the underlying geometry. AMG is often used not as a

standalone solver but as a preconditioner within an iterative solver (e.g.

Conjugate Gradients, BiCGStab, or GMRES).

AMGCL builds the AMG hierarchy on a CPU and then transfers it to one of the

provided backends. This allows for transparent acceleration of the solution

phase with help of OpenCL, CUDA, or OpenMP technologies. Users may provide

their own backends which enables tight integration between AMGCL and the user

code.
