Meta to Detail Networking Lessons for Gigawatt-Scale AI Clusters at Hot Interconnects
thoefler · x · 2026-08-14
At the upcoming Hot Interconnects 2026 conference, Meta's network engineering lead will deliver a keynote sharing lessons and challenges learned from networking gigawatt-scale AI compute fleets.
Additionally, the conference agenda covers several cutting-edge interconnect technologies, including:
- Photonic Interconnects: Lightmatter discussing BiDi DWDM as the foundation for high-performance AI training, and scaling inference prefill using high-radix photonic interconnects.
- Ultra-Scale Networking: Multipass random leaf-spine network designs tailored for extreme-scale computing systems.
- Novel Transports: Application-centric Multipath Reliable Connection (MRC), and petabit-class switching breaking the network wall for single-hop MoE training.
