Full QCD simulation on CP - PACS ∗
A status report is made of an on-going full QCD study on the CP-PACS aiming at a comparative analysis of the effects of improving gauge and quark actions on hadronic quantities and static quark potential. Simulations are made for four action combinations, the plaquette or an RG-improved action for gluons and the Wilson or SWclover action for quarks, at a ≈ 1.1-1.3GeV and mπ/mρ ≈ 0.7-0.9. Result...
متن کاملFull QCD Light Hadron Spectrum and Quark Masses : Final Results from CP - PACS ∗ CP - PACS
We present the final results of the CP-PACS calculation of the light hadron spectrum and quark masses with two flavors of dynamical quarks. Simulations are made with a renormalization-group improved gauge action and a mean-field improved clover quark action for sea quark masses corresponding to mPS/mV ≈ 0.8–0.6 and the lattice spacing a = 0.22–0.11 fm. For the meson spectrum in the continuum li...
متن کاملPerformance of lattice QCD programs on CP-PACS
The CP-PACS is a massively parallel MIMD computer with the theoretical peak speed of 614 GFLOPS which has been developed for computational physics applications at the University of Tsukuba, Japan. We report on the performance of the CP-PACS computer measured during recent production runs using our Quantum Chromodynamics code for the simulation of quarks and gluons in particle physics. With the ...
متن کاملCP - PACS results for quenched QCD spectrum with the Wilson action ∗ CP - PACS
We present progress report of a CP-PACS calculation of quenched QCD spectrum with the Wilson quark action. Light hadron masses and meson decay constants are obtained at β =5.9, 6.1, and 6.25 on lattices with a physical extent of 3 fm, and for the range of quark mass corresponding to mπ/mρ ≈ 0.75 − 0.4. Nucleon mass at each β appears to be a convex function of quark mass, and consequently the va...
متن کاملCP-PACS results for light hadron spectrum in quenched and two- avor full QCD
We present a summary of our results for the light hadron spectrum in quenched lattice QCD and preliminary ones in twoavor full QCD. For the quenched hadron spectrum we nd that the mass formulae predicted by quenched chiral perturbation theory(QChPT) give a good description of our results. Employing the QChPT mass formulae for chiral extrapolations we conclude that the mass spectrum in the conti...
