Description
FermiQCD is a C++ library for fast development of parallel Lattice Quantum Field Theory computations. It has been developed following a top-down fully Object Oriented design approach with focus on simplicity of use. We present simulations for the hadron spectrum with the Wilson action in quenched QCD carried out on the BG HPC cluster, using this tool kit. Testing Fermiqcd as a tool kit for parallel lattice QCD applications and see how parallel calculations are implemented in this package are some aims of this work. Simulations are made with the plaquette gauge action on 8^4, 12^4 and 16^4 lattices at three lattice spacings, for a total number of 300 SU(3) gauge configurations. The masses of pi and rho – meson, nucleon and delta baryons are computed for these conditions. For a constant physical volume we study the dependence of the hadron masses on the lattice spacing. After chiral and continuum extrapolations, the agreement of the calculated mass spectrum for this kind of fermions with experiment is reasonable.
