Abstract： We present the results for π, ρ, proton and Δ masses from our recently built Pentium cluster and compare with the quenched Wilson fermion data presented by MILC and GF11 collaborations [Nucl.Phys.B (Proc.Suppl.) 60A(1998)3, Nucl. Phys. B 430(1994)179] at β = 6/g2 = 5.7 and 5.85 on the 83 x 32 lattice. New data are shown at β = 6.25 on the 123 x 36 and 163 x 32 lattices. Such a larger β value is useful for extrapolating the lattice results to the continuum limit. The smearing technique is systematically investigated and can greatly improve the spectrum data.
