Physics-based simulation generates offline visual effects in the film and animation industry. However, the computations required for high-quality scenarios are generally immense, deterring its adoption in real-time applications such as virtual production, avatar livestreaming, and cloud gaming. We'll summarize the principles that can accelerate the computation pipeline on single-GPU and multi-GPU platforms through extensive investigation and comprehension of modern GPU architecture. We'll further demonstrate the effectiveness of these principles by applying them to the material point method to build up our framework, which achieves 1.7-8.6x speedup on a single GPU and 2.5-14.8x on four GPUs, compared to the state of the art. Our pipeline is specifically designed for real-time applications (i.e., scenarios with small to medium particles) and achieves significant multi-GPU efficiency.
