Abstract
A comparison of SAMG and CAMG multigrid methods to solve systems of linear algebraic equations obtained at discretization of elliptic equations is carried out on practical examples. The key peculiarities and implementation details of Krylov subspace iterative methods and multigrid methods for computer systems with GPU accelerators are discussed.
