This research used computational resources of HA-PACS and COMA provided by the Interdisciplinary Computational Science Program of Center for Computational Sciences at University of Tsukuba (No. 17a13), SR16000 and BG/Q by the Large Scale Simulation Program of High Energy Accelerator Research Organization (KEK) (Nos. 13/14-21, 14/15-23, 15/16-T06, 15/16-T-07, 15/16-25, 16/17-05), and Oakforest-PACS at JCAHPC through the HPCI System Research project (Project ID:hp170208). This work was in part based on Lattice QCD common code Bridge++ [28].

N2 - We study the energy-momentum tensor and the equation of state as well as the chiral condensate in (2+1)-flavor QCD at the physical point applying the method of Makino and Suzuki based on the gradient flow. We adopt a nonperturbatively O(a)- improved Wilson quark action and the renormalization group-improved Iwasaki gauge action. At Lattice 2016, we have presented our preliminary results of our study in (2+1)- flavor QCD at a heavy u; d quark mass point. We now extend the study to the physical point and perform finite-temperature simulations in the range T ? 155.544 MeV (Nt = 4-14 including odd Nt's) at a ? 0:09 fm. We show our final results of the heavy QCD study and present some preliminary results obtained at the physical point so far.
