N2 - We report the progress on the lattice QCD calculation of the glue spin contribution to proton spin. This calculation is carried out with valence overlap fermion on 2+1 flavor DWF gauge configurations at two lattice spacings with the momentum of the frame in the kinematic range 0 ≤ p2 ≤ 2 GeV2 . A mild frame dependence is observed. The matching and mixing with largemomentum effective field theory are in progress. The unrenormalized result at p2 = 4 GeV2 with O(a2) correction gives SG = 0.13(3).
