We present the results for πr, p, proton and A 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 atβ=6.25 on the 12a × 36 and 163 × 32 lattices. Such a largeβ 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.
