To train large language models using distributed GPU clusters, leverage Megatron-Core to apply tensor, pipeline, context, and expert parallelism. This approach maximizes throughput for models ranging from 2B up to 462B parameters.

3D parallelism combines tensor, pipeline, and data parallelism to efficiently train enormous models across multi-node GPU clusters. You need it when scaling models beyond single GPU memory limits to maximize overall training efficiency.

Yes, you can use FP8 training and Flash Attention with Megatron-Core. It integrates the Transformer Engine to provide these acceleration features, significantly increasing model FLOPs utilization and overall training throughput.

Distributed LLM training supports Mixture of Experts architectures through expert parallelism. This allows you to efficiently train large MoE models alongside standard tensor and pipeline parallelism within multi-node GPU clusters.

The best way to configure multi-node deployment for LLaMA-scale models is using production-grade training recipes with Megatron-Core. This provides 3D parallelism and FP8 acceleration to maximize throughput on distributed GPU clusters.
