Abstract

A parallelization scheme, which drives processing in simulations of the Monte Carlo type, suitable in highly heterogeneous computer system of a general purpose, is proposed. The message passing is applied and the MPI library is exploited. For testing, the 2D Ising model in a magnetic field is taken. The dependence of speedup on the number of parallel processes is studied, showing that the scheme works well in different parallel computer systems. The condition for the best speedup in these simulations is explained. The possibility of parallel use of any available computing power from the surrounding is also indicated.
