Posted: Fri Aug 28, 2026 5:41 pm
Researchers from Georgia Institute of Technology published a technical paper titled “Thermal Tuning Overhead in Wafer-Scale Optical Interconnects for LLM MoE Training: A Cross-Layer Analysis and Ferroelectric-Based Mitigation.” Abstract Excerpt: The paper analyzes “wafer-scale optical interconnects” for mixture-of-experts LLM training and finds “repeated tuning stalls during communication phases.” It also reports “speedups of 2.7x” for Mixtral 8x7B when tuning stalls are eliminated.
