SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Pretraining large language models at scale requires complex setup of distributed training, 4‑dimensional parallelism, and specialized hardware features. This Skill abstracts those steps, letting users launch high‑performance LLM pretraining without manual wiring of FSDP, tensor, pipeline, and context parallelism.

Core Features & Use Cases

  • 4D Parallelism: Combines FSDP2, tensor, pipeline, and context parallelism for models from 8 B to 405 B parameters.
  • Float8 Support: Enables FP8 training on H100 GPUs for up to 48 % speed‑up.
  • Multi‑node SLURM integration: Ready scripts for single‑node and large‑scale cluster jobs.
  • Model flexibility: Works with Llama 3.1, DeepSeek V3, custom architectures, and conversion utilities.
  • Use case: Quickly start pretraining a Llama 3.1 70 B model across 256 GPUs with a single configuration file.

Quick Start

Ask the skill to launch distributed training of Llama 3.1 8B on eight GPUs using the default configuration.

FAQPage Schema
How do I start distributed LLM pretraining with TorchTitan on multiple GPUs?▼

To start distributed LLM pretraining, use TorchTitan to launch models like Llama 3.1 8B across eight GPUs using a single default configuration file without manual FSDP wiring.

What is 4D parallelism and how does it handle large language model training?▼

4D parallelism handles large language model training by combining FSDP2, tensor, pipeline, and context parallelism to efficiently scale pretraining for models ranging from 8B to 405B parameters.

Does TorchTitan support Float8 acceleration on H100 GPUs?▼

Yes, TorchTitan supports Float8 acceleration on H100 GPUs through optional torchao integration, providing up to a 48% speed-up during large language model pretraining.

Can I use this distributed pretraining setup for custom model architectures?▼

Yes, you can use this distributed pretraining setup for custom model architectures, as well as Llama 3.1 and DeepSeek V3, along with provided conversion utilities.

Do I need PyTorch 2.6 to run 4D parallelism with TorchTitan?▼

Yes, you need PyTorch version 2.6 or higher and TorchTitan version 0.2 or higher to run 4D parallelism and execute distributed pretraining scripts.

What's the best way to scale Llama 3.1 70B pretraining across a SLURM cluster?▼

The best way to scale Llama 3.1 70B pretraining is using TorchTitan's multi-node SLURM integration, which provides ready scripts to scale jobs across 256 or more GPUs.
