Abstract: We report on the status of code development for a simulation of Quantum Chromodynamics (QCD) with dynamical Wilson fermions on the Connection Machine model CM-2. Our original code, written in *Lisp, gave performance in the near-GFLOPS range. We have rewritten the most time-consuming parts of the code in the low-level programming system CMIS, including the matrix multiply and the communication. Current versions of the code run at approximately 3.6 GFLOPS for the fermion matrix inversion, and we expect the next version to reach or exceed 5 GFLOPS.
