Distributed training with Ray Train DLCs and EFA on EKS
TL;DRRay Train simplifies multi-GPU training on AWS by bundling CUDA and networking tools.
Why it matters: Reduces setup friction for distributed deep learning, letting teams focus on models instead of infrastructure.
The Ray Train Deep Learning Container ships the full CUDA-through-EFA stack, so you build no image. This post walks through a reproducible sample that fine-tunes Qwen2.5-1.5B with PyTorch FSDP across eight GPUs on two EFA-enabled g6.12xlarge instances on Amazon EKS, using the…
