Abstract

We present an overview of our project of simulation of unquenched lattice QCD with optimal domain-wall quarks, using a GPU cluster currently constituting of 16 units of Nvidia Tesla S1070 plus 64 graphic cards with Nvidia GTX285 (total 128 GPUs with 128 Teraflops peak), attaining sustained computing power of 15.36 Teraflops. The first production run in two-flavor QCD is on-going, using the Iwasaki gauge action on a set of lattices with sizes 163×(32,10,8,6,4)×(16,32) 16^3 \times (32,10,8,6,4) \times (16,32) at the lattice spacing a0.1 a \sim 0.1 fm, with eight sea quark masses down to mπ200 m_\pi \simeq 200 MeV. We outline our simulation algorithm, and describe the present status of the production run. Preliminary results of pseudoscalar mass and decay constant are also presented.
