We will share the latest updates to NCCL and how they can be used in PyTorch. We invite the community to share their feedback on challenges using NCCL at scale and ways to improve integration of NCCL with PyTorch applications.

Some of the important topics for community discussion include:
- Symmetric memory support and GPU-initiated networking.
- Copy-engine collectives and maximizing overlap of communication and computation for better end-to-end performance.
- Profiling, debugging and tuning, as well as resilience (handling failed nodes without a restart).
