      abstract     = {A number of stochastic methods developed for the
                      calculation of fermion loops are investigated and compared,
                      in particular with respect to their efficiency when
                      implemented on Graphics Processing Units (GPUs). We assess
                      the performance of the various methods by studying the
                      convergence and statistical accuracy obtained for
                      observables that require a large number of stochastic noise
                      vectors, such as the isoscalar nucleon axial charge. The
                      various methods are also examined for the evaluation of
                      sigma-terms where noise reduction techniques specific to the
                      twisted mass formulation can be utilized thus reducing the
                      required number of stochastic noise vectors.},
