## Summary

NVIDIA's Technical Blog says a single GPU or fabric event can cause NCCL errors, scheduler state changes, and many downstream messages in distributed AI workloads, so the reported exception shows where a job stopped rather than where the failure began. The post explains how to run NVIDIA Attribution on sample workload evidence to trace the root cause.
