The second intercollaborational workshop of RIKEN-BNL-Columbia (RBC) and UKQCD collaborations was organized as the RIKEN-BNL Research Center Workshop entitled Physics Programs of the RBRC and UKQCD QCDOC Computers and held at Brookhaven National Laboratory on November 12th and 13th, 2004. At the time of the meeting, two l2K-node QCDOC configurations, one in Edinburgh and the other at the RIKEN-BNL Research Center in Brookhaven were soon to become available for lattice QCD numerical calculations. Indeed the Edinburgh configuration had been successfully assembled and verified in Brookhaven during the preceding months, and was just shipped from Brookhaven and then received in Edinburgh. The RIKEN configuration was being assembled. As of this writing, the two configurations are now complete and ready to start physics calculations. Since the first intercollaborational workshop held in Edinburgh in December, 2003, some members of the two collaborations had been discussing possible advantages of jointly producing gauge configurations with dynamical domain-wall fermion quark and improved gauge actions.
