Debugging idle GPUs in K8s with Kubeflow and Cilium is highly technical, actionable, and directly relevant to cloud infrastructure and data engineering.
Summary
This article likely details a real-world debugging scenario where distributed training jobs on Kubeflow showed 60% GPU idle time despite appearing healthy. The investigation probably reveals that Cilium's network policies or eBPF-based networking caused bottlenecks, leading to underutilized GPUs. It offers a case study on diagnosing subtle infrastructure issues in ML workloads on Kubernetes.
