version: "1.0.1" name: nvrx-attr description: > Orchestration layer over nvidia_resiliency_ext attribution modules. Provides log-analysis, fr-analysis, and a Megatron-LM-oriented fault-injection feedback loop for benchmarking attribution quality on SLURM workloads. compatibility: Requires Python 3.10+, nvidia-resiliency-ext[attribution] installed, and LLM_API_KEY (env var, LLM_API_KEY_FILE, or ~/.llm_api_key). The fault-injection loop has only been validated with Megatron-LM workloads. metadata: author: nvidia

Attribution Skills

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.

The Analyzer (analyzer/engine.py) is the recommended entry point when you need request coalescing, result caching, or the combined LOG_AND_TRACE pipeline. Use the individual skills when you want to run one analysis type directly without the full coalescing stack.

Common prerequisites

• LLM_API_KEY environment variable, LLM_API_KEY_FILE, or ~/.llm_api_key
• Package installed: pip install 'nvidia-resiliency-ext[attribution]' or pip install -e '.[attribution]' from repo root
• 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.
