Operationalizing Large Language Model Training Pipelines
summary
Operationalizes training for trillion-parameter LLMs using Megatron and DeepSpeed on A100/H100 clusters, claiming runs that span weeks and consume thousands of GPUs; presents concrete tooling: tensor/sequence/pipeline parallelism, ZeRO optimizer, flash attention, mixed-precision and activation checkpointing, and KB-cache plus quantization for serving. Describes automated recovery with frequent checkpointing, anomaly detection on gradients and activation shifts, dynamic resource reallocation, and alerts; reports cost drivers like high cost-per-failed-hour and shows methods that reduce training time and wasted GPU-hours.
