The Performance of CUDA with the Flexibility of PyTorch

This talk explores how PyTorch users are also becoming CUDA developers. We'll start with motivating examples from eager, the launch of torch.compile and the more recent trend of kernel zoos. We will share details on how we went about integrating low bit matmuls in torchao and the torch.compile CUTLASS backend. We'll also discuss details on how you can define, build and package your own custom ops in PyTorch so you get the raw performance of CUDA while maintaining the flexibility of PyTorch.
