ZeRO-Infinity

2000년 도입 · 논문 2편에서 사용

ZeRO-Infinity is a sharded data parallel system that extends ZeRO with new innovations in heterogeneous memory access called the infinity offload engine. This allows ZeRO-Infinity to support massive model sizes on limited GPU resources by exploiting CPU and NVMe memory simultaneously. In addition, ZeRO-Infinity also introduces a novel GPU memory optimization technique called memory-centric tiling to support extremely large individual layers that would otherwise not fit in GPU memory even one layer at a time.
