Resumé

We report on simulations with two flavors of O(a) improved degenerate Wilson fermions with Schroedinger functional boundary conditions. The algorithm which is used is Hybrid Monte Carlo with two pseudo-fermion fields as proposed by M. Hasenbusch. We investigate the numerical precision and sensitivity to reversibility violations of this algorithm. A gain of a factor two in CPU cost is reached compared with one pseudo-fermion field due to the larger possible step-size.
