💡 This Skill includes references (resource) components.

What problem does it solve?

This skill enables scalable, PyTorch-native distributed pretraining of large language models using 4D parallelism (FSDP2, TP, PP, CP) across multi-GPU clusters with features like Float8, torch.compile, and distributed checkpointing.

Core Features & Use Cases

  • Supports composable 4D parallelism (FSDP2, tensor, pipeline, context) for large-scale LLM pretraining.
  • Integrates with TorchTitan tooling and standard model workflows to accelerate training across 8–512+ GPUs.
  • Use Case: Pretrain Llama-family or custom models at scale with robust checkpointing and interop with HuggingFace.

Quick Start

Install torchtitan, create a 4D parallelism config TOML, and launch the training script on your multi-GPU cluster.

FAQPage Schema
How do I set up distributed LLM pretraining with 4D parallelism using PyTorch?

Distributed LLM pretraining with 4D parallelism is enabled through composable FSDP2, tensor, pipeline, and context parallelism. You configure a TOML file and launch the training script on a multi-GPU cluster using TorchTitan APIs and torch.compile.

Can I use Float8 precision for large-scale LLM pretraining across multi-GPU clusters?

Yes, Float8 precision is supported for large-scale LLM pretraining across 8–512+ GPU clusters. It integrates with FSDP2 and torch.compile to accelerate training while maintaining robust distributed checkpointing.

What is the best way to orchestrate tensor and pipeline parallelism for Llama-family models?

The best way to orchestrate tensor and pipeline parallelism for Llama-family models is using composable 4D parallelism via TorchTitan. This PyTorch-native approach supports scalable pretraining with standard model workflows and HuggingFace interoperability.

Does distributed pretraining with FSDP2 support distributed checkpointing and HuggingFace integration?

Distributed pretraining with FSDP2 supports robust distributed checkpointing and HuggingFace interoperability. It leverages TorchTitan tooling to manage training workflows across 8–512+ GPUs efficiently.

How many GPUs do I need to run PyTorch-native distributed pretraining with context parallelism?

PyTorch-native distributed pretraining with context parallelism applies to clusters ranging from 8 to 512+ GPUs. It uses composable 4D parallelism orchestration to scale large language model training effectively.
