Phys.Lett.B345:49-54,1995 The polarization of Polyakov type loops is responsible for the difference
between quenched and unquenched finite size effects on the QCD mass spectrum.
With a numerical ...simulation, using different sea quarks boundary conditions, we
show that we can align the spatial Polyakov loops in a predefined direction.
Starting from these results, we propose a procedure to partially remove the
Polyakov type contributions in the meson propagators.

This paper presents the status of the APEmille project, which is essentially completed, as far as machine development and construction is concerned. Several large installations of APEmille are in use ...for physics production runs leading to many new results presented at this conference. This paper briefly summarizes the APEmille architecture, reviews the status of the installations and presents some performance figures for physics codes.

APENEXT is a new generation APE processor, optimized for LGT simulations. The project follows the basic ideas of previous APE machines and develops simple and cheap parallel systems with multi ...T-Flops processing power. This paper describes the main features of this new development.
We present numerical results obtained in full QCD with 2 flavors of Wilson fermions. We discuss the relation between the phase of Polyakov loops and the {\bf sea} quarks boundary conditions. We ...report preliminary results about the HMC autocorrelation of the hadronic masses, on a \(16^3 \times 32\) lattice volume, at \(\beta=5.55\) with \(k_{sea}=0.1570\).
