FAQPage Schema

How do I run distributed LLM pretraining with PyTorch across multiple GPUs?▼

Distributed LLM pretraining with PyTorch uses torchtitan to distribute and optimize model training across multiple GPUs. It targets large-scale scenarios by implementing 4D parallelism to handle workloads from 8 to 512+ GPUs.

What is 4D parallelism and how does it help with LLM pretraining?▼

4D parallelism for LLM pretraining combines FSDP2, Tensor Parallelism, Pipeline Parallelism, and Context Parallelism. This PyTorch-native approach optimizes performance and memory distribution when scaling large model training across multiple GPUs.

Do I need specific PyTorch versions to use torchtitan for scale-up training?▼

Yes, torchtitan for scale-up training requires PyTorch version 2.6.0 or higher, torchtitan 0.2.0 or higher, and torchao 0.5.0 or higher. These dependencies provide the necessary compilation and numerical methods for execution.

Can I use this approach to pretrain Llama 3.1 models on H100 GPUs?▼

Yes, you can pretrain Llama 3.1 models on H100 GPUs using this PyTorch-native approach. It is specifically designed to scale LLM pretraining for models like Llama 3.1 8B and DeepSeek V3 starting from 8 GPUs.

What's the best way to accelerate large language model pretraining with float8?▼

To accelerate LLM pretraining with float8, use this PyTorch-native approach which integrates advanced numerical methods like float8 and torch.compile. This enhances performance during large-scale distributed training across multiple GPUs.
