Fairscale activation checkpoint
WebOct 18, 2024 · We use the fully_sharded distributed_training.ddp_backend provided by the fairscale library and and set model.activation_checkpoint to true. We also increase dataset.max_tokens to 2560000 and use a total effective batch size of 2560000*24. We sweep for the best optimization.lr within the interval [3e−6,3e−5] using dev error rate. WebEfficient memory usage using Activation Checkpointing Adapted from torch.utils.checkpoint, this is a friendlier wrapper for performing activation checkpointing. Compared to the PyTorch version, this version wraps a nn.Module and allows for all subsequent calls to be checkpointed.

WebActivation checkpointing is a technique used to reduce GPU memory usage during training. This is done by avoiding the need to store intermediate activation tensors during the forward pass. Instead, the forward pass is recomputed by keeping track of the original input during the backward pass.
