Characterizing Job Power Elasticity for Power-Flexible AI Training
The first systematic characterization of job power elasticity (the sensitivity of throughput to power reductions) in LLM training is presented, and the Power Flexibility Index (PFI) is introduced, a normalized metric that quantifies the performance cost of power reductions and provides a control primitive for SLA-aware...
