Straggler Mitigation On PyTorch DDP By Hierarchical SGD

PyTorch DDP has been widely adopted across the industry for distributed training, which by default runs synchronous SGD to synchronize gradients across model replicas at every step. The performance of this technique is critical for fast iteration during model exploration as well as resource and cost saving. The performance is critical for fast iteration and cost saving of model development and exploration. To resolve a ubiquitous performance bottleneck introduced by slow nodes in large-scale ...

PyTorch & OpenXLA: The Path Forward

As we celebrate the release of OpenXLA, PyTorch 2.0, and PyTorch/XLA 2.0, it’s worth taking a step back and sharing where we see it all going in the short to medium term. With PyTorch adoption leading in the AI space and XLA supporting best-in-class compiler features, PyTorch/XLA is well positioned to provide a cutting edge development stack for both model training and inference. To achieve this, we see investments in three main areas:

Accelerated PyTorch 2 Transformers

The PyTorch 2.0 release includes a new high-performance implementation of the PyTorch Transformer API with the goal of making training and deployment of state-of-the-art Transformer models affordable. Following the successful release of “fastpath” inference execution (“Better Transformer”), this release introduces high-performance support for training and inference using a custom kernel architecture for scaled dot product attention (SPDA).

PyTorch 2.0 & XLA—The Latest Cutting Edge Features

Today, we are excited to share our latest work for PyTorch/XLA 2.0. The release of PyTorch 2.0 is yet another major milestone for this storied community and we are excited to continue to be part of it. When the PyTorch/XLA project started in 2018 between Google and Meta, the focus was on bringing cutting edge Cloud TPUs to help support the PyTorch community. Along the way, others in the community such as Amazon joined the project and very quickly the community expanded. We are excited about X...

Accelerated Diffusers with PyTorch 2.0

PyTorch 2.0 has just been released. Its flagship new feature is torch.compile(), a one-line code change that promises to automatically improve performance across codebases. We have previously checked on that promise in Hugging Face Transformers and TIMM models, and delved deep into its motivation, architecture and the road ahead.
