Problem – Frequent Pod Evictions on AMD GPU Nodes During Disaster Recovery During disaster‑recovery (DR) drills the AI training platform experiences a surge of concurrent training jobs. On clusters that use AMD MI250X GPUs the kubelet repeatedly evicts pods with the reason=OutOfmemory condition. Typical symptoms observed: Pods transition to Evicted status within minutes of the … Read more
