Thermodynamics using p4-improved staggered fermion action on QCDOC
  We present an exploratory study of the thermodynamics of $N_f=3$ QCD with an improved staggered fermions using the QCDOC supercomputer. We use a p4 action with MILC-style smeared links (Fat 7). Some details of the implementation of the p4 action on QCDOC are discussed and performance benchmarks are given. We show preliminary results for the quark mass dependence of the pseudo-critical temperature $T_c$ from several lattice volumes . We also make a comparison between p4fat7 and the old p4 action.
