WebOftentimes, optimizers also maintain local states. For example, the Adam optimizer uses per-parameter exp_avg and exp_avg_sq states. As a result, the Adam optimizer’s memory consumption is at least twice the model size. Given this observation, we can reduce the optimizer memory footprint by sharding optimizer states across DDP processes.
