New algorithm Spectra optimizes optical switches for AI training

By PulseAugur Editorial · [1 sources] ·

A new paper proposes Spectra, an algorithm designed to optimize the scheduling of parallel optical circuit switches (OCSes) for AI training. This method addresses the challenge of managing time-varying traffic demands and reconfiguration delays across multiple OCSes. Spectra decomposes traffic demands into weighted permutations, schedules them across switches, and balances loads through permutation splitting. Evaluations on AI workloads, including GPT and Qwen MoE, show Spectra significantly reduces schedule makespan compared to existing algorithms. AI

IMPACT Could significantly reduce latency and energy consumption in large-scale AI training infrastructure.
