Bound states of multi-nucleon channels in N_f=2+1 lattice QCD
Takeshi Yamazaki, Ken-ichi Ishikawa, Yoshinobu Kuramashi +1
We calculate the energies for multi-nucleon ground states with the nuclear mass number less than or equal to 4 in 2+1 flavor QCD at the lattice spacing of a = 0.09 fm employing a r…
Finite size scaling for 4-flavor QCD with finite chemical potential
Shinji Takeda, Xiao-Yong Jin, Yoshinobu Kuramashi +2
We explore the phase diagram spanned by the temperature and the chemical potential for 4-flavor QCD by the phase-reweighting approach. In order to determine the order of phase tran…
Multi-block/multi-core SSOR preconditioner for the QCD quark solver for K computer
T. Boku, K. -I. Ishikawa, Y. Kuramashi +7
We study the algorithmic optimization and performance tuning of the Lattice QCD clover-fermion solver for the K computer. We implement the Lüscher's SAP preconditioner with sub-blo…
