Megatron-MoE-ModelZoo is a production-ready toolkit for training Mixture-of-Experts (MoE) large language models including DeepSeek-V3, Qwen3, and Mixtral. It provides SLURM job submission scripts, Dockerfiles for hardware-optimized containers, YAML configuration files, and best practice guides for launching training jobs on HPC clusters. The repository integrates with NVIDIA's Megatron-LM framework (dev branch) to enable efficient distributed training of MoE models across tensor, pipeline, and expert parallelism dimensions. Key features include precision selection (BF16/FP8/MXFP8), checkpoint conversion utilities, and memory estimation tools for hardware planning.
