Meta's Research SuperCluster(RSC): Accelerating AI Research at Scale

Meta is facing a challenging and exciting future as it expands beyond its current capabilities in the social space. Ensuring our platform is open to as many diverse cultures, languages and perspectives is a significant challenge that requires intensive large-scale AI models. The complexities of adding a virtual reality Metaverse further increases the challenge space, requiring much larger models with greater numbers of modalities and parameters.

Meta anticipated these challenges and has built a dedicated high-performance state-of-the art cluster to accelerate AI research. We present the architectural choices that went into building the cluster composed of 16K GPUs, high-performance storage and a non-blocking Infiniband network. We will discuss some of the lessons learned and how they have been applied to Meta in general.

Finally, we reflect on the impact the RSC has had on our research projects, and provide some insight into future directions.

09:25 AM - 09:40 AM

Building AI capacity is essential to the future of our company, and supporting AI workloads at scale requires a different approach than scaling to support our regular online services. Our new data center design will support the next generation of AI systems. We are building an increased level of flexibility into our design, which will allow us to pivot in response to shifts and changes in the AI space.

The new design will have fewer but denser racks to support large scale AI clusters, allowing us to have a smaller footprint while serving the same capacity as our previous data center designs. This design was created with efficiency at the forefront. Each data center going forward will be optimized for water and energy usage depending on the site/region, and will continue to incorporate sustainable features to ensure efficient facilities. We anticipate this design will also be faster and cheaper to build.

Pytorch 2.0

What makes PyTorch beloved makes it harder to compile. After almost five years, we finally cracked the technologies that made it possible to compile any PyTorch model, resulting in a step-function change in PyTorch’s approach to execution efficiency. We called it PyTorch 2.0.

PyTorch 2.0 delivers significant performance improvements over a wide variety of models, often with just a simple one-liner change. This talk focuses on the two critical technologies underlying PyTorch 2.0, TorchDynamo and TorchInductor.

PyTorch 2.0 was released in March. But do not mistake it as the end of the story. The first release of PyTorch 2.0 marks the beginning of a roadmap for improving PyTorch execution efficiency via compiled mode.

MTIA: Meta's First Generation of AI Accelerators

Meta has traditionally relied on using CPU-based servers for running AI workloads, but the increasing compute and memory requirements of these models have pushed the company towards using specialized solutions such as GPUs or other hardware accelerators. This talk describes the company's effort in constructing its first silicon designed for its internal AI workloads and systems; It describes the accelerator architecture and platform design, and the software stack for enabling and optimizing workloads. It also touches upon the upcoming challenges and evolving requirements that need to be accommodated moving forward.

MSVP: Meta's Scalable Video Processor

This presentation will introduce MSVP (Meta's Scalable Video Processor), the first generation server grade video processing hardware accelerator of its kind developed at Meta. We will describe the motivation behind it, the architecture, and some of the novel algorithms that are in the video encoder and other video processing blocks to achieve high video quality. We will also describe how the hardware accelerators are used in Meta’s data center to support processing and transcoding billions of videos every day and provide premium video quality to end users, while saving power.

Gen AI-Assisted Code Authoring at Meta

At Meta, we have built upon existing research published by FAIR to develop our own AI-Assisted code authoring tools. The freedom to experiment with the model combined with the ability to train on first-party code has enabled us to deliver tooling that has had a measurable impact on developer productivity.
