AN IMPROVED APPROACH TO PARALLEL DISCRETE-EVENT SIMULATION BASED ON COW

Recently the performance of parallel simulation has attracted a great attention in computer science. Most of the works have devoted to minimize the time consumption in simulation processing, whereas this paper stresses the advantages of the parallel discrete-event simulation of VHDL based on COW. In the paper it describes the advantages of COW and MPI and focus on the key points in the PDES and what the improvement we do on Time Warp mechanism to decrease the time in communication processing.
