SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Enables scalable, PyTorch-native distributed pretraining of large language models with 4D parallelism across multiple GPUs.

Core Features & Use Cases

  • 4D parallelism (FSDP2, TP, PP, CP) enables efficient scaling from 8 to 512+ GPUs.
  • Float8 training and compile-based optimizations accelerate LLM pretraining on H100s.
  • Interoperability with torchtune/HuggingFace for checkpoints and shared workflows.
  • Use cases include pretraining Llama 3.1, DeepSeek V3, and custom models at scale.

Quick Start

Install TorchTitan and launch an 8-GPU Llama 3.1 pretraining run using the configured settings.

FAQPage Schema
How do I scale LLM pretraining across multiple GPUs using PyTorch?▼

To scale LLM pretraining across multiple GPUs, you can use this Skill to implement 4D parallelism. It enables PyTorch-native distributed pretraining for models like Llama 3.1 across 8 to 512+ GPUs.

What is 4D parallelism and how does it help with distributed training?▼

4D parallelism combines FSDP2, Tensor Parallelism, Pipeline Parallelism, and Context Parallelism to distribute LLM pretraining. It allows efficient scaling of large models up to 512+ GPUs without bottlenecks.

Can I use Float8 training to accelerate LLM pretraining on H100 GPUs?▼

Yes, you can use Float8 training to accelerate LLM pretraining on H100 GPUs. This Skill supports Float8 and torch.compile optimizations to maximize hardware utilization during distributed training.

Does this distributed training approach work with HuggingFace checkpoints?▼

Yes, this distributed training approach works with HuggingFace checkpoints. It features interoperability with torchtune and HuggingFace to support shared workflows and distributed checkpointing.

How do I start an 8-GPU Llama 3.1 pretraining run?▼

To start an 8-GPU Llama 3.1 pretraining run, install TorchTitan and launch the job using the configured settings. This provides an end-to-end PyTorch-native distributed training workflow.
