STEMS: Spatio-Temporal Scheduling to Accelerate LLM Training in Optically Interconnected Clusters

All-optical interconnects (AOIs) provide large yet reconfigurable bandwidth with high energy efficiency, making them key enablers for sustaining the rapid expansion of large language model (LLM) training clusters. However, the flexibility of AOIs can never be fully exploited if not jointly optimized with the collective...
