Torch Pipeline Parallelism

소개

Provides a comprehensive framework for scaling large language models beyond single-device memory limits by partitioning model layers across multiple GPU ranks. This skill guides developers through the complexities of All-Forward-All-Backward (AFAB) scheduling, microbatching, and efficient inter-rank tensor communication while ensuring stable gradient flow and addressing architecture-specific challenges like rotary position embeddings. It is an essential resource for engineering high-performance distributed training systems for massive transformer-based architectures.
