In this blog post we’ll describe nvFuser and how it’s used today, show the significant performance improvements it can obtain on models from HuggingFace and TIMM, and look ahead to nvFuser in PyTorch 1.13 and beyond. If you would like to know more about how and why fusion improves the speed of training for Deep Learning networks, please see our previous talks on nvFuser from GTC 2022 and GTC 2021.
