AB - The lattice Boltzmann method has become a promising numerical technique and  is now being considered as an alternative to the conventional CFD methods  owing a possibility to simulate more complex geometries at relatively low  computational costs. The simulations of complex and very fine resolution  computational domains in CFD is challenging due to the lack of memory  resources and long processing times, therefore parallel computing is being  considered as a promising way to cope with this ever increasing mission of  computational power. In this work parallelization of 2-D lattice Boltzmann  model based CFD code using message passing interface was performed to  increase speedup factor for parallel computing. Lattice Boltzmann approach  based CFD code of a benchmark Lid driven cavity flow problem was  parallelized using different message passing interface subroutines and made  to run on a cluster system of processors. The time and speed up factor for  execution of the benchmark problem was investigated. The results showed that  these message passing communications have little influence on the  performance of the parallel lattice Boltzmann method.
