Abstract
Computations in lattice field theories account for a significant fraction of time allocated for parallel computing. Goals and methods of lattice simulations be briefly reviewed. The local nature of lattice field theory algorithms makes them good candidates for parallelization. I describe in some detail a MIMD implementation easily adaptable to various physical contents, portable to many parallel environments, and efficiently hiding internode communications. As an illustration, I show results from recent numerical simulations of matter nonconservation in the early Universe, performed on the UNI*C SP2 parallel machine.

As the subject of baryogenesis has undergone a spectacular development in recent years, it is yet to be covered by a truly non-technical review. A determined reader can consult a review by A.D. Dolgov, Phys. Rep. 222 (1992) 309. Recent developments in the field are reflected in Electroweak physics and the early Universe, edited by J.C. Romao and F. Freire, Plenum Press, New York (1994).
