I can confirm that with this PR, I'm able to run CPU-offload on a 6B parameters models with limited RAM (32GB). Usage peaks at 24GB before going down to a constant 20GB. The same test script crashes due to OOM on the last version of DeepSpeed. |

Thank you for validating the fix, @sgugger! Tunji, is it good to merge? as quite a few users are impacted by this memory issue and your PR would help to many. Thank you! |

Parameter offloading can live separately from stage 3 optimizer, right?
