Large-scale particle tracking is important for precise design and optimization of the linear accelerator. In this paper a parallel software recently developed for beam dynamics simulation has been benchmarked. The software is based on Particle-In-Cell method, and calculates space charge field by an efficient three-dimension parallel fast Fourier transform method. It uses domain decomposition and MPI library for parallelization. The characteristics of this software are optimized software structure and suitable for modern supercomputers. Several standard accelerating devices have been used to compare the simulation results with other beam dynamics software. They have been run on several different platforms, such as INSPUR cluster at RDCPS, and SHENGTENG7000 at IMPCAS. At first, some simulation results for RFQ with large number of particles will be shown.
