Preliminary Study of B_K on 2+1 flavor DWF lattices from QCDOC
  I present some preliminary calculations of B_K on 2+1 flavor domain-wall fermion lattices from the QCDOC, including a set of 16^3x32x8 lattices with a^{-1} near 1.6 GeV. Although a final result awaits the production of a much longer run, I will compare this preliminary value to previous results.
