# 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.

* [ICLR Accepted version with ZB1P and ZB2P](https://openreview.net/pdf?id=tuzTN0eIO5)

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.
