Abstract We present new parallel software, SUSY LATTICE, for lattice studies of four-dimensional N = 4 supersymmetric Yang–Mills theory with gauge group SU( N ). The lattice action is constructed to exactly preserve a single supersymmetry charge at non-zero lattice spacing, up to additional potential terms included to stabilize numerical simulations. The software evolved from the MILC code for lattice QCD, and retains a similar large-scale framework despite the different target theory. Many routines a... Title of program: SUSY LATTICE Catalogue Id: AELS_v2_0 Nature of problem To carry out non-perturbative Monte Carlo importance sampling for maximally supersymmetric Yang-Mills theories in two and four dimensions, and thereby compute observables including Wilson loops, fermion bilinears, eigenvalues of D † D and the Pfaffian of the sparse fermion operator D.
