Strong scaling result of different GPU. Both GPUs’ scalabilities deviate from linear result, but the efficiencies are all larger than 75% when 10 GPUs are utilized. The drops of scalability come from the fact that when grid size decreases, the speedup drops too, see Fig. 13. Scalability of Titan V drops faster than RTX 2080 Ti’s, because the speedup of Titan V drops faster than RTX 2080 Ti’s when the grid size decreases
