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.

Try out our implementation based on Megatron on 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.
