Optimized Research for Mobile Communication Strategy Based on Parallel Computing

Abstract:

In order to improve the speed of simulation, one of the feasible approaches in mobile communications is parallel computing. In this paper, the operating environment will be achieved with MPICH2. Parallel computing is suitable for large scale computing tasks. An important factor which limits the speed-up ratio improve is that parallel computing cannot be achieved in communication process.Selecting the finite difference method, taking a two-dimensional steady-state heat distribution problem act as an example. By choosing domain decomposition method divide the entire data area into multiple sub-domains. Ultimately, the parallel program is designed in MPI’s Peer-to-Peer Model. By modifying the communication mode and the communication process, the speedup is substantial increased, closing to ideal values.
