Abstract

The invention discloses a method executed at a graphics processing unit 'GPU' and used for conducting simulation on spallation reaction, as well as electronic equipment comprising the GPU. The method comprises the following steps: (a) receiving initial information related to spallation reaction, wherein the initial information at least comprises particle attributes and particle energies of particles; (b) determining the number of reactive particles according to the particle attributes and the particle energies; (c) if the number is zero, stopping the method, or determining the particle states of corresponding particles according to the particle attributes and the particle energies; (d) aiming at the particles with the same particle state, concurrently executing processing or modeling corresponding to the particle state, updating the particle attributes, the particle energies and the particle states of the corresponding particles according to the results of the processing or modeling, and returning to the step (b).

Description

technical field [0001] The present disclosure generally relates to the technical field of multi-particle generation and multi-particle transport simulation in the process of spallation, and more specifically, relates to a research method applicable to the generation and mixed transport of neutrons, protons and various lightly charged particles. A GPU-based approach to Monte Carlo transport simulation. Background technique [0002] Unless otherwise indicated herein, what is described in this section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Based on the development requirements of ADS (Accelerator Driven Sub-critical System), it is of great significance to the simulation of particle generation and particle transport process in the physical process of spallation. So far, there are mainly two methods for solving the transport process: the deterministic method and the Monte Carlo method. The Mo...
