Even when every GPU, network link, and pod reports healthy, a 512-GPU training job can underperform or fail. The cause may be one slow GPU, a link that degrades under load, or a configuration that quietly routes traffic over a slower path. Operators may not discover the problem until hours into the run or until a…</p> <p><a href="https://developer.nvidia.com/blog/validate-gpu-cluster-readiness-before-ai-workloads-land/" rel="nofollow" data-wpel-link="internal" target="_self">Source</a></p>
