Here’s how to isolate and fix the problem: 1. Verify the Problem Identify whether the issue affects specific systems, services, or the entire network. Try pinging the hostname (e.g., ping […]
Multi-GPU deep learning works when the hardware, software stack, and training strategy line up. Miss one and you’ll waste cycles debugging throughput instead of training models. 1. Choose the Right Hardware GPU Selection: Pick GPUs built for deep learning: NVIDIA A100, RTX 4090, or RTX 3090/3080. VRAM must fit your largest model plus activations and […]
Custom metrics let you scale Kubernetes workloads on signals that matter to your application, not just CPU or memory. Here’s how to wire them into the Horizontal Pod Autoscaler. 1. Understand HPA and Custom Metrics HPA pulls metrics from the Kubernetes Metrics API. For custom metrics, you need a component that serves those metrics to […]
