What is the main reason for testing with different GPU clusters consisting of 2, 3, and 4 NVIDIA A100 GPUs respectively? Thank you for your question. We tested different numbers of GPU clusters to verify the scalability of our approach. The results show good scalability, that is, the acceleration ratio of 4 GPUs is close to 4 (the number of GPUs). This scalability makes it possible to apply our approach to a cluster of 8 GPUs or even 64 GPUs, potentially increasing rendering performance 8-fold or 64-fold.
