We present numerical results obtained in full QCD with 2 flavors of Wi
lson fermions. We discuss the relation between the phase of Polyakov l
oops and the sea quarks boundary conditions. We report preliminary res
ults about the HMC autocorrelation of the hadronic masses, on a 16(3)
x 32 lattice volume, at beta = 5.55 with kappa(sea) = 0.1570.
