We perform dynamical QCD simulations with nf ≤ 2 overlap fermions by hybrid Monte-Carlo method on 64 to 83 × 16 lattices. We study the problem of topological sector changing. A new method is proposed which works without topological sector changes. We use this new method to determine the topological susceptibility at various quark masses.
