AI overview

AWS demonstrated distributed PyTorch training on Amazon EKS using its published Ray Train Deep Learning Container, KubeRay, and Elastic Fabric Adapter (EFA), without building a custom container. The sample ran Qwen2.5-1.5B with Fully Sharded Data Parallel (FSDP) across eight NVIDIA L4 GPUs on two g6.12xlarge instances, using random token batches to verify training and communication between nodes. The guide covers cluster deployment, transport verification, workload configuration, and cleanup. Its demonstration verifies the training setup and cross-node communication using synthetic inputs.
