This software implements the classical statistical simulation of SU(3) Yang-Mills theory in (classical) thermal equilibrium in (3+1)d, based on the naive Wilson plaquette action. Formulated as Hamiltonian equations of motion in temporal gauge, the time evolution is implemented via the symplectic leap-frog scheme. Distribution of the computation among different computing nodes relies on the PETSC library (tested on v.3.14).

In order to compile the source code, the PETSC_DIR and PETSC_ARCH variables must be correctly set in the make-file "MakefilePETSC". In addition the code requires the presence of the Eigen library (tested on v.3.3.9), whose path must also be set in the make-file. In order to ensure that the code can be compiled in the long term, the corresponding versions of both libraries are included in the source code package.
