A parallel Direct Simulation Monte Carlo (DSMC) algorithm to solve a spatially inhomogeneous nonlinear equation of coagulation is presented. The algorithm is based on simulating the evolution of stochastic test particles ensembles. The algorithm can be effectively implemented on parallel computers of different architectures including GRID infrastructure based on MPLS networks. A problem of minimizing the computational cost of the algorithm is considered. To implement the algorithm on GRID infrastructure we carry out preliminary simulation of an underlying network. Such simulation enables to define minimal network bandwidth necessary for efficient parallel decomposition of DSMC algorithm.
