SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

TorchTitan enables PyTorch-native distributed pretraining of large language models using composable 4D parallelism across multi-GPU clusters.

Core Features & Use Cases

  • 4D parallelism across FSDP2, tensor parallelism (TP), pipeline parallelism (PP), and context parallelism (CP) to scale pretraining.
  • Float8 training on H100 with selective filtering and compile-stage acceleration for speedups.
  • Checkpoint interoperability with HuggingFace and torchtune to save, resume, and convert checkpoints.
  • Multi-node workflows including 8 to 512+ GPU clusters and SLURM-based launches for large-scale pretraining.

Quick Start

Launch a pretraining job on 8 GPUs using a ready config and the training script.
