CoreWeave Core Workflow: GPU Training

Overview

Run distributed GPU training on CoreWeave: single-node multi-GPU and multi-node training with PyTorch DDP, Slurm-on-Kubernetes, and shared storage.

Prerequisites

• CKS cluster with multi-GPU node pools (8xA100 or 8xH100)
• Shared storage (CoreWeave PVC or NFS)
• Training container with PyTorch and NCCL
