  We consider the implementation of a parallel Monte Carlo code for
high-performance simulations on PC clusters with MPI. We carry out tests of
speedup and efficiency. The code is used for numerical simulations of pure
SU(2) lattice gauge theory at very large lattice volumes, in order to study the
infrared behavior of gluon and ghost propagators. This problem is directly
related to the confinement of quarks and gluons in the physics of strong
interactions.
