AWhat changed
Extended ZeRO with hierarchical GPU/CPU/NVMe offloading, memory-centric layer tiling, bandwidth-centric state partitioning and transfer/computation overlap.
Scientific scope
Extended ZeRO with hierarchical GPU/CPU/NVMe offloading, memory-centric layer tiling, bandwidth-centric state partitioning and transfer/computation overlap. Extends ZeRO and ZeRO-Offload rather than inventing sharded states or heterogeneous memory. Ability to fit or run a giant model is not completed high-quality end-to-end pretraining at that scale; throughput and overlap depend on hardware, batch sizes and bandwidth. Disk/CPU resources and transfer costs remain.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
