Abstract
This invention discloses a parallel processing method, system, platform, and storage medium for particle contact search in a distributed memory architecture. The method generates and acquires first data corresponding to the particle computing region, and generates corresponding second data based on the first data. Based on the second data, at least four levels of particle container units corresponding to the particles are created. A first mechanism corresponding to particle contact is constructed. Based on the first mechanism, the migration and transfer states of particles are searched and processed in parallel within the particle container units in the computing domain. The first mechanism is a particle state mechanism. The system, platform, and storage medium corresponding to the method can reduce the time spent on contact search and the computer memory usage when discrete numerical computation methods such as discrete unit methods use distributed memory for computation.
