FAQPage Schema
How do I run distributed LLM pretraining with 4D parallelism in PyTorch?▼

Distributed LLM pretraining with 4D parallelism is enabled natively through TorchTitan, utilizing FSDP2, Tensor Parallel, Pipeline Parallel, and Context Parallel across multi-node GPU clusters.

Can I pretrain Llama 3.1 or DeepSeek V3 using native PyTorch across multiple GPUs?▼

Yes, you can pretrain Llama 3.1 or DeepSeek V3 across 8 to 512+ GPUs using native PyTorch configurations, complete with distributed checkpointing and Float8 support.

What PyTorch version is required for FSDP2 and Float8 distributed training?▼

FSDP2 and Float8 distributed training require PyTorch version 2.x or higher, alongside the torchtitan and torchao libraries to execute the 4D parallelism workflows.

Does torchtitan support multi-node checkpointing for large-scale model training?▼

Yes, TorchTitan supports distributed checkpointing for multi-node, multi-GPU configurations, ensuring training state recovery and scalability for large language model pretraining.

What is the best way to scale custom model pretraining from 8 to 512 GPUs?▼

Scaling custom model pretraining to 512+ GPUs is best handled using TorchTitan's 4D parallelism, combining FSDP2, TP, PP, and CP with torch.compile optimizations.
