## What it does

This skill covers NeMo AutoModel launches through `torchrun`, Slurm, and SkyPilot. Interactive mode needs no extra YAML section: the CLI routes to `torchrun` when the config has neither `slurm:` nor `skypilot:`.

For Slurm, it explains job fields, container images, mounts, environment variables, and distributed launch settings. SkyPilot configuration covers the cloud provider, accelerators, node count, disk, region, and `setup`. The launcher sets `MASTER_ADDR`, `MASTER_PORT`, and `WORLD_SIZE` for multi-node training.

The skill also covers Nsight Systems profiling with `nsys profile` in Slurm jobs. Profiling writes a `.nsys-rep` report and adds overhead, so it belongs in short diagnostic runs rather than normal production training. SkyPilot spot instances can be preempted; short checkpoint intervals and `restore_from.path` are needed for resume handling.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemo-automodel-launcher-config -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nemo-automodel-launcher-config/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nemo-automodel-launcher-config/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemo-automodel-launcher-config -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nemo-automodel-launcher-config/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemo-automodel-launcher-config -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nemo-automodel-launcher-config/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills nemo-automodel-launcher-config
```

2. **Manually: put the files in place**

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/nemo-automodel-launcher-config
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nemo-automodel-launcher-config/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill nemo-automodel-launcher-config -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/nemo-automodel-launcher-config/SKILL.md

## When to use it
- configure an interactive NeMo AutoModel launch
- write a Slurm job configuration
- prepare multi-node training settings
- set up a SkyPilot cloud launch
- profile a Slurm job with Nsight Systems

## Example prompts
- Configure a `nemo-automodel` launch on Slurm with two nodes and the required environment variables.
- Prepare a SkyPilot spot configuration that resumes from `/checkpoints/latest`.
- Show how to enable `nsys_enabled: true` for a short Slurm profiling run.

# Launcher Configuration

NeMo AutoModel supports three launch methods: interactive (torchrun), Slurm (HPC clusters), and SkyPilot (cloud-agnostic).

## Instructions

For launcher questions, answer directly from this skill without inspecting the
repository unless the user asks you to edit files. Keep the answer focused on
the relevant launch YAML, required fields, and the expected runtime behavior.

Use these compact answer patterns for common questions:

- Slurm multi-node: show a `slurm:` YAML block with `job_name`, `nodes`,
  `ntasks_per_node`, `time`, `account` or `partition`, `container_image`,
  `hf_home`, optional `extra_mounts`, `env_vars`, and `master_port`; explain
  that the launcher derives `WORLD_SIZE = nodes * ntasks_per_node` and sets
  `MASTER_ADDR` and `MASTER_PORT`.
- SkyPilot spot: show a `skypilot:` YAML block with `cloud`, `accelerators`,
  `num_nodes`, `use_spot: true`, `disk_size`, `region`, `setup`, and
  `env_vars`; warn that spot instances can be preempted, set a short
  `step_scheduler.checkpoint_interval`, and resume with `restore_from.path`.
- Nsight Systems on Slurm: show `slurm.nsys_enabled: true` alongside normal
  Slurm fields, say the launcher wraps the training command with
  `nsys profile`, and state that it produces a `.nsys-rep` report file.
  Treat profiling as diagnostic-only: use short profiling runs and disable it
  for normal production training because it adds overhead and large artifacts.

For Slurm answers, start with this minimal template and then adjust only the
fields the user asked about:

```yaml
slurm:
  job_name: llm_finetune
  nodes: 2
  ntasks_per_node: 8
  time: "04:00:00"
  account: my_account
  partition: batch
  container_image: nvcr.io/nvidia/nemo:dev
  hf_home: ~/.cache/huggingface
  master_port: 13742
  env_vars:
    HF_TOKEN: "${HF_TOKEN}"
```

For Slurm-only questions, do not discuss SkyPilot or profiling unless the user
asks. For profiling questions, say the `.nsys-rep` report is written in the
Slurm job working or output directory, using the launcher's Nsys output setting
when one is configured.
