FAQPage Schema

What is communication overlap in distributed training?▼

Communication overlap is a performance optimization technique that concurrently executes network communication and GPU computation during distributed training, reducing bottlenecks to improve overall throughput.

How do I configure TP, DP, and PP overlap settings in Megatron-Bridge?▼

You configure TP, DP, and PP overlap settings in Megatron-Bridge by applying specific configuration snippets and environment adjustments to enable concurrent communication and computation during large-scale model training.

Why does my large-scale model training have low GPU utilization?▼

Low GPU utilization during large-scale model training often results from communication bottlenecks. Implementing communication overlap allows computation to run concurrently with network data transfers, maximizing efficiency and throughput.

Can I trace throughput regressions using communication overlap techniques?▼

Yes, you can trace throughput regressions by reviewing performance verification steps and overlap configurations. This helps identify communication bottlenecks and optimize model training speed in distributed environments.

Do I need specific environment settings to enable communication overlap?▼
