Abstract: Solving systems of equations obtained in Discontinuous Galerkin method by GPU-computing is considered. The direct method and iterative Krylov methods with preconditioning are used. The performance of GPU-computing for these systems of equations is compared with one of multicore CPU.

Keywords: discontinuous Galerkin method, system of linear algebraic equations, Krylov subspaces methods, preconditioner, sparse matrices, general purpose сomputing on GPU.
