Building the next-generation AI/ML networking
1/N 📢 Introducing UCCL (Ultra & Unified CCL), an efficient collective communication library for ML training and inference, outperforming NCCL by up to 2.5x 🚀 Code: github.com/uccl-project/u… Blog: uccl-project.github.io/posts/about-uc… Results: AllReduce on 6 HGX across 2 racks over RoCE RDMA

We add an updated NCCL vs. UCCL performance figure with an explanation on why there is a sudden performance drop for NCCL.

Excited to share UCCL! RDMA networks is slow to evolve, causing performance bottlenecks for ML workloads. UCCL tackles this by moving more control logic to software, enabling better performance (up to 2.5x than NCCL) and flexibility (supporting different GPU/NIC vendors)
