FAQPage Schema

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

You scale LLM pretraining across multiple GPUs by applying 4D parallelism (FSDP2, TP, PP, CP) with TorchTitan to distribute large-scale model training workloads across 8 to 512+ GPUs efficiently.

What is the best way to pretrain Llama 3.1 or DeepSeek V3 on a multi-node GPU cluster?▼

The best way to pretrain Llama 3.1 or DeepSeek V3 is using TorchTitan to automate 4D parallelism workflows, which simplifies large-scale multi-node experiments and supports distributed checkpointing for custom architectures.

Can I use Float8 and torch.compile to maximize pretraining throughput on H100 GPUs?▼

Yes, you can use Float8 support with compile-time acceleration to maximize pretraining throughput on H100 and Blackwell hardware, optimizing large-scale distributed model training performance.

Do I need specific PyTorch versions to run distributed pretraining with 4D parallelism?▼

Yes, distributed pretraining with 4D parallelism requires PyTorch >=2.x, torchtitan >=0.2.0, torchao >=0.5.0, and access to multi-node GPU clusters to execute scalable LLM training workflows properly.

How does distributed checkpointing work with HuggingFace after large-scale pretraining?▼

Distributed checkpointing works with HuggingFace by providing checkpoint interoperability and integration with torchtune, enabling seamless model deployment and fine-tuning after large-scale pretraining completes.
