In this paper the implementation of a molecular diffusion model based on Dynamic Lattice Liquid (DLL) algorithm is discussed. Two approaches to such implementation, sequential and parallel, are examined. The presented theoretical considerations indicate some limitations of the sequential approach. The proposed parallel implementation overcomes these limitations, but it requires a dedicated hardware to function. The example of such hardware, the FPGA-based, HPC device named ARUZ is briefly described. The presented experimental results prove the efficiency of this device.
