Abstract: Particle transport non-deterministic simulation is one of the main applications of high performance computers, and plays an important role in national economic construction and national security. Currently the nuclear numerical simulation, nuclear reactor design, aerospace and other practical applications have impending needs for high-precision particle transport non-deterministic simulation, thus its acceleration methods have become a research hotspot in the high-performance computing field. In recent years there are many different contributions to research on particle transport simulation. In this paper, the principle of particle transport non-deterministic simulation is firstly introduced. Then the basic flow and pseudocode of the particle transport simulation program is given. Subsequently, the latest software acceleration methods and the hardware acceleration methods are summarized. Finally, based on the extracted program features from the architecture simulator, the current challenges are discussed, and the future research directions based on relate research work are outlined.
