WebbIn addition, PipeDream-2BW automatically partitions the model over the available hardware resources, while respecting hardware constraints such as memory capacities of accelerators and interconnect topologies. PipeDream-2BW can accelerate the training of large GPT and BERT language models by up to 20x with similar final model accuracy. WebbWhile PipeDream is oblivious to memory usage, its enhancement, PipeDream-2BW [18], targets large models that do not necessarily ﬁt on a single accelerator. Exploiting the repetitive structure of some of these large models, such as transformer-based language models, PipeDream-2BW’s planner only considers conﬁgurations where every stage
