Algebraic multigrid preconditioning of sparse symmetric positive definite matrices, backed by Trilinos MueLu. More...

Detailed Description

The preconditioner of a sparse matrix A applies one multigrid cycle to A z = r. It is a host-side operator that launches device kernels; it is not device-callable.
