# Zero Bubble Pipeline Parallelism

Zero Bubble Pipeline Parallelism is a novel pipeline parallelism algorithm able to reduce the bubble of pipeline parallelism to almost zero while preserving synchronous semantics.

Check out our paper at:
* [Arxiv Version with ZBV](https://arxiv.org/abs/2401.10241)
* [ICLR Accepted version with ZB1P and ZB2P](https://openreview.net/pdf?id=tuzTN0eIO5)

Try out our implementation based on Megatron on [https://github.com/sail-sg/zero-bubble-pipeline-parallelism](https://github.com/sail-sg/zero-bubble-pipeline-parallelism)

Experiments shows zero bubble pipeline parallelism can accelerate training up to 30% with a similar memory comsumption. A detailed table of experiments is coming soon.
