Fugaku is the Japanese flagship supercomputer operated by RIKEN Center for Computational Science. It started its test operation in 2020 and the full service from 2021.
We have been using Fugaku for Lattice QCD computations, using Wilson Fermions mainly in PACS collaboration and domain wall fermions (DWF) mainly in JLQCD collaboration for past three years.
In this talk a status report on the DWF simulations especially on QCD thermodynamics are given. There are several projects in this category, in which, studies of thermodynamics near the physical point using a line of constant physics and phase structure in three degenerate flavors are discussed in detail, emphasizing how to control the residual chiral symmetry breaking at coarse lattices, which is important for these simulations.
