Abstract

We present results for $\pi$ , $\rho$ and proton and $\Delta$ masses from our recently built Pentium cluster. The previous results for quenched Wilson fermions by MILC and GF11 collaborations are compared at $\beta=6/g^2$ =5.7 and 5.85 with the same parameters on the $8^3\times32$ lattice. New data are shown at $\beta$ =6.25 on the $12^3\times36$ and $16^3\times32$ lattices. Such a larger $\beta$ value is useful for extrapolating the lattice results to the continuum limit. The smearing technique is systematically investigated and shown to greatly improve the spectrum data.
