System Documentation

What problem does it solve?

Overcoming communication bottlenecks in Megatron-Bridge by enabling overlap among tensor-parallel, data-parallel, and pipeline-parallel paths during distributed training.

Core Features & Use Cases

  • Config-driven overlap: Tune tensor-model-parallel size, sequence parallel, and pipeline parallel size to achieve simultaneous data, tensor, and pipeline communications.
  • Code anchors & guidance: Provides code anchors and practical pitfalls to ensure correct overlap behavior and safe deployment.
  • Verification & troubleshooting: Includes verification steps, pitfalls to avoid, and launch-time environment tuning recommendations for different scheduling modes.

Quick Start

Enable TP/DP/PP overlap in Megatron-Bridge by applying the CommOverlapConfig knobs shown in the skill and verify the overlap behavior with the provided unit tests.
