NVIDIA SPECTRUM-X — THE OPEN, AI-NATIVE ETHERNET FABRIC — SETS THE STANDARD FOR GIGASCALE AI, NOW WITH MRC

Summary from the TLDR AI newsletter

Multipath Reliable Connection (MRC) is an RDMA transport protocol that enables a single RDMA connection to distribute traffic across multiple network paths. This improves throughput, load balancing, and availability for large-scale AI training fabrics. MRC delivers high levels of GPU utilization by load-balancing traffic across all available paths. It gives administrators fine-grained visibility and control over traffic paths to simplify operations and accelerate troubleshooting at scale.
