Heavy-ion collision simulation with high performance computer

Dae Ik Kim, Chang-Hwan Lee, Youngman Kim, Sangyong Jeon

Abstract

Heavy-ion collision is an important tool to understand the dense nuclear matter properties. In order to understand the results of the heavy-ion collision experiments, both theoretical approaches to dense nuclear matter using effective models and the computer simulations with given theoretical models have been performed. Due to the complexity of the system and the theoretical framework, the heavy-ion collision simulations require heavy computer resources. In this talk, we report our recent preliminary work on the heavy-ion collision simulation using DaeJeon Boltzmann-Uehling-Uhlenbeck (DJBUU) and Sindong Quantum Molecular Dynamics (SQMD) model with high performance computers (HPC).
