We summarize the project of the light meson spectrum with $N_f$=2+1
overlap fermions by JLQCD and TWQCD.
We study the finite size effect by directly comparing results from two
different lattice volumes. Through the chiral extrapolation carried out
with additional data points with $m_{ud} = m_s$, we test the prediction
of chiral perturbation theory.

Hadron spectroscopy
We give an overview of our simulations of
2-flavors and (2+1)-flavors QCD with optimal domain-wall fermions,
using a GPU cluster with 200 Tflops(peak)/36 Tflops(sustained).
We work on a lattice of size $ 16^3 \times 32 $, with lattice cutoff
$ a^{-1} \simeq 1.6 $ GeV, and eight dynamical (sea) quark masses in the
range $ m_s/8 - m_s $, where $ m_s $ is the physical strange quark...

We present results from simulations performed by ETMC using $2+1+1$ flavours of twisted mass fermions at maximal twist. We concentrate on one value of the lattice spacing of $a\approx 0.078$fm, but we add first data at a second value of $a=0.06$fm to test for the size of lattice artefacts. The quark mass dependence of light meson masses and decay constants will be confronted to chiral...

Hadron spectroscopy
We present first results for the pseudoscalar decay constants $f_K$, $f_D$ and $f_{D_s}$ in lattice QCD with dynamical up, down, strange and charm quark flavours. The investigation is based on gauge configurations generated by the ETM collaboration using $N_f=2+1+1$ Wilson twisted mass fermions at maximal twist at one value of the lattice spacing around 0.08 fm and several values of the light...
