[SY-F14] Large-scale multiphase flow simulations on a GPU supercomputer

Invited

^○Takayuki Aoki (Tokyo Institute of Technology, Japan)

GPU (Graphics Processing Unit) was originally designed for graphics rendering and has been widely used for supercomputers in the world, since it has high computational performance and wide memory bandwidth and suitable for scientific computing. We have developed stencil codes written in CUDA and executed them on a GPU supercomputer TSUBAME. Several simulations of gas-liquid and gas-solid two-phase flows are demonstrated with the numerical methods and the algorithms such as AMR (Adaptive Mesh Refinement) and dynamic load balance for efficient large-scale simulations.
