핵심 지표

Gradient accumulation steps × pipeline stages = 2-4× memory footprint. 4 accumulation steps × 4 pipeline stages = 16× baseline batch memory requirement

요약

Distributed training with gradient accumulation and pipeline parallelism compounds memory demands: each stage holds partial activations, all multiplied by accumulation buffer depth

Vibe Coding Economy 정합성

Pipeline parallelism architecture inherently requires in-flight activation storage at multiple stages → exponential memory multiplicand
