Pre-training can act as a grid knob: on 2048 GPUs, curtailment falls from 1.077 to 0.014 MWh
In a 2048-GPU, renewable-direct-supply AI data center, embedding checkpoint waiting and feasible 3D-parallel GPU modes of LLM pre-training into day-ahead dispatch cuts operating cost by 20.02% and renewable curtailment from 1.077 to 0.014 MWh relative to fixed continuous training.
