High-level orchestration layer over the nvidia_resiliency_ext.attribution modules.
Each subdirectory is a self-contained skill with its own SKILL.md and helper scripts.
Skills
| Directory | Purpose | Entry point |
|---|---|---|
log-analysis/ | Analyze SLURM job logs for failure root-cause and restart decisions | RestartAgent (python -m nvidia_resiliency_ext.attribution.restart_agent.cli) |
fr-analysis/ | Analyze NCCL flight-recorder dumps for collective-hang root-cause | CollectiveAnalyzer (fr_attribution.py) |
fault-injection-loop/ | Run a batched SLURM fault-injection feedback loop and score attribution accuracy | prepare_node_alloc.sh / watch_and_analyze.sh |

Use the packaged restart_agent and trace_analyzer entry points for current
log and FR analysis. Legacy LogSage, SPLITLOG, and combined LogSage+FR tools live
under attribution/legacy_logsage/ for source-checkout workflows only.
Common prerequisites
LLM_API_KEYenvironment variable,LLM_API_KEY_FILE, or~/.llm_api_key- Source checkout or installed package with the attribution extra for restart-agent and FR analysis
- The fault-injection loop has only been validated with Megatron-LM training scripts
Fault-Loop Local Setup
Before using fault-injection-loop/, create the local config file from the tracked
template and fill in your site-specific values:
cp scripts/user.env.example scripts/user.env
The feedback-loop scripts require src/nvidia_resiliency_ext/skills/nvrx-attr/scripts/user.env
to exist at runtime. Keep user.env local and untracked.
