What is DualPipe?

DualPipe is an innovative bidirectional pipeline parallelism technology developed by DeepSeek, designed to improve the training efficiency of large-scale deep learning models. It decouples the forward and backward propagation of the model into two independent pipelines, executed in parallel, reducing pipeline stalling and achieving overlap between computation and communication.

Main Features of DualPipe

  • Large-scale Model Training: DualPipe decouples forward and backward propagation into independent pipelines, reducing pipeline stalling and improving computational resource utilization.
  • Bidirectional Pipeline Design: Forward and backward computations are executed in parallel, enabling computation parallelization.
  • Overlap of Computation and Communication: Optimized scheduling ensures complete overlap between computation and communication, reducing idle time.
  • Memory Optimization: Reduces peak memory demand, allowing for the training of larger models with limited hardware resources.

Technical Principles of DualPipe

  • Bidirectional Pipeline Design: Forward and backward computations are decoupled into independent pipelines, executed in parallel.
  • Overlap of Computation and Communication: Optimized scheduling reduces idle time in the pipeline, improving resource utilization.
  • Memory Optimization: Forward and backward computations can be executed at different times, reducing peak memory demand.
