Abstract: For the further research of network simulation performance in heterogeneous computing environment, this paper introduces evaluation model for the performance of network simulation in heterogeneous computing environment. At first, this paper analyzes the factors affecting network simulation task in heterogeneous computing environment, including synchronization overhead, remote communication overhead, routing simulation overhead, packet forwarding and simulation overhead. Then, this paper puts forward evaluation model for the performance of network simulation in heterogeneous computing environment. Afterwards, this paper proposes the corresponding analysis and test methods on its model influence factors. The experimental results indicate that the evaluation model can accurately estimate the performance of large-scale network simulation task in heterogeneous computing environment. Compared with the real value, the average error coefficient is 3.2%; there is an obvious decrease in the average error coefficient relative to the current evaluation model for performance.
