What is DeepSpeed ZeRO++?

DeepSpeed ZeRO++ is an innovative system crafted to enhance the efficiency of training large-scale deep learning models by optimizing communication strategies. It builds on the existing Zero Redundancy Optimizer (ZeRO) to significantly lower communication volume, boosting training speed and reducing operational costs. Particularly useful in settings limited by bandwidth or resources, it distinguishes itself by offering enhanced scalability and throughput. By reducing communication-related bottlenecks, it accelerates the training of models, especially beneficial for large language models (LLMs) and deep learning systems requiring extensive computational power. ZeRO++ is easily integrated with existing frameworks, needing minimal code changes, thus proving highly functional for researchers and developers.
