Parallelization of processing in Monte Carlo simulations of the Ising spin system with the lattice distributed in a stripe way is proposed.Message passing is applied and one-sided MPI communication with the MPI memory window is exploited.The 2D Ising spin lattice model is taken for testing purposes.The scalability of processing in our simulations is tested in real-life computing on high performance multicomputers and discussed on the basis of speedup and efficiency.The larger the lattice the better scalability is obtained.
