Title
M131: a conjugate gradient algorithm implementation with energy-norm stopping criteria
Contributors

Abstract
We present an implementation of the preconditioned conjugate gradient method that is based on reverse communication to allow the user to incorporate his or her own matrixvector multiplication routine and preconditioning algorithm. Our implementation also includes new stopping criteria that take into account some recent results on the approximation of the energy norm of the error during the conjugate gradient iterative process. We present the results of several numerical tests that experimentally validate the effectiveness of the stopping criteria on defnite-element approximations of selected 2-D and 3D problems.
