N1  - We thank the QCDSF Collaboration for allowing us to use their N<INF>f</INF> = 2 configurations [8-11] and the ILDG for making them available [12]. We thank Thomas Lippert for support, and Zoltan Fodor and Stefan Sint for discussion. We acknowledge partial support in SFB/TR-55. CPU resources on JUROPA were provided by Forschungszentrum Julich GmbH.
AB  - We determine the quark mass ratio m(c)/m(s) on the lattice, using Wilson-type fermions. Configurations with N-f = 2 dynamical clover-improved fermions by the QCDSF Collaboration are used, which were made available through the ILDG. In the valence sector we use a sophisticated, mass-independently O(a)- improved Wilson-type action with small cutoff effects even in the charm mass region. After an extrapolation to the physical pion mass, to zero lattice spacing and to infinite box volume, we find m(c)/m(s) = 11.27(30)(26).
