MILC-based code for pure-gauge SU(N) lattice Yang--Mills theories with arbitrary number of colors Top-level directories follow the MILC layout generic -- Procedures common to most applications: communications, I/O, data layout, pure-gauge computations, etc. generic_nhyp -- Procedures common to nHYP-smeared applications, needed for Wilson flow include -- Header files for common procedures libraries -- Single processor linear algebra routines Then there are currently two application directories, each with more detailed READMEs: pure_gauge -- Pure-gauge evolution and LLR density of states wilson_flow -- Wilson flow with optional RG-blocking and measurements Finally, the testsuite directory contains some sample input files and corresponding output for testing
