International Conference on High Performance Computing in Asia-Pacific Region, Tokyo, Japan, Jan 28-31 (2018).
Even for the significant advances in CPU computing power and high performance computing, direct whole-core neutron transport
calculation still remains unfeasible for the industrial applications. Furthermore, the improving trend of CPU technology is being
challenged nowadays by thermal and power constraints. Thus, heterogeneous computing is increasingly receiving attention as an
alternative for reactor physics. This work suggests a method to accelerate method of characteristics neutron transport calculation
with anisotropic scattering treatment on GPUs. The method was implemented in nTRACER, a direct whole-core neutron transport
calculation code being developed by Seoul National University.
