Brickner, R G

Our collaboration has been running Wilson fermion QCD simulations on various Connection Machines for over a year and a half. During this time, we have continually optimized our code for operations found in the fermion matrix inversion. Our current version of the matrix inversion is written almost entirely in CMIS (Connection Machine Instruction Set), and utilizes both high-speed arithmetic and multiwire news'' (nearest-neighbor communications). We present details of how these and other features of our code are implemented on the CM-2. 4 refs., 2 tabs.
