Abstract
We compare different conjugate gradient-like matrix inversion methods (CG, BiCGstab1 and BiCGstab2) employing for this purpose the compact l attice quantum electrodynamics (QED) with Wilson fermions. The main go als of this investigation are the CPU time efficiency of the methods a s well as the influence of machine precision on the reliability of (ph ysical) results especially close to the 'critical' line kappa(c)(beta) .
