                         clusters with a multi-core architecture. We simulated atmosphere

                         configurations on performance and scalability. Our analyses 
                         consider execution in intra-node and inter-node configurations of 
                         a cluster with 24 cores per node. Results reveal differences in 
                         the BRAMS performance caused by interconnection. The BRAMS may get 
                         better performance by using a newer version of MPI library
