Performance modeling and analysis of heterogeneous lattice Boltzmannn simulations on CPU-GPU clusters

摘要

Computational fluid dynamic simulations are in general very compute intensive. Only by parallel simulations on modern supercomputers the computational demands of complex simulation tasks can be satisfied. Facing these computational demands GPUs offer high performance, as they provide the high floating point performance and memory to processor chip bandwidth. To successfully utilize GPU clusters for the daily business of a large community, usable software frameworks must be established on these c
