# Checkpoint-aware dispatch

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.
