## What it does

The skill stages a job specification on shared Lustre storage, builds a batch script, and submits it to the cluster over SSH. It checks the script before submission and records job state; `squeue` and `sacct` are used to inspect jobs.

You need passwordless SSH access to a SLURM login node, plus `SLURM_USER` and `SLURM_HOSTNAME` environment variables. Job data and outputs must be reachable from the cluster, so files that exist only on the agent machine cannot serve as inputs. Private `nvcr.io` images require persistent Enroot credentials on the cluster; without them, authenticated image pulls fail. For a standalone setup, run the `tao-setup` skill first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-run-on-slurm -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tao-run-on-slurm/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tao-run-on-slurm/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-run-on-slurm -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tao-run-on-slurm/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-run-on-slurm -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tao-run-on-slurm/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills tao-run-on-slurm
```

2. **Manually: put the files in place**
- File: `.github/skills/tao-run-on-slurm/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-run-on-slurm -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/tao-run-on-slurm
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tao-run-on-slurm/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-run-on-slurm -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/tao-run-on-slurm/SKILL.md

## When to use it
- submit a TAO job to a SLURM GPU cluster
- prepare a Pyxis/Enroot batch script
- check job state with SLURM commands
- record job details and results

## Example prompts
- Run TAO training on the SLURM cluster using the dataset already on Lustre.
- Prepare a Pyxis/Enroot job script and submit it with `sbatch`.
- Check the SLURM job state and locate its results.

# SLURM

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

Remote GPU compute platform for clusters managed by SLURM. Jobs are submitted
from the launch host to a login node over SSH, staged on a shared
filesystem, submitted with `sbatch`, and executed with `srun` container support.

## When to use

Use SLURM when the user has access to a managed GPU cluster, shared Lustre
storage, and scheduler-owned GPU allocation. Do not use SLURM for local files
that exist only on the agent machine; data and outputs must be reachable from
the cluster.

## Preflight + SSH

Confirm `SLURM_USER` and `SLURM_HOSTNAME` are exported and passwordless SSH to a
login host works (`ssh -o BatchMode=yes`).
The launch host needs `ssh`, not local `sbatch`, `srun`, Enroot, or a Lustre
mount. Preflight those scheduler, Pyxis, Enroot, and shared-storage dependencies
on the selected remote login/compute frame. Model-specific inspectors may be
streamed from the installed skill over SSH stdin; do not stage an ad-hoc source
patch or treat the launch host as the SLURM frame.
For private `nvcr.io` images, install `~/.config/enroot/.credentials` on the
cluster once per (cluster, user): Pyxis/Enroot does not read `NGC_KEY` from the
job env, and without persistent credentials, auth-gated pulls fail with "Could
not process JSON input" at job startup. Install it via the `printf | ssh`
heredoc so the `NGC_KEY` value never lands in shell history, intermediate files,
or chat output; never `cat`/`echo` the value.

If a preflight check fails, the agent prompts the user to authorize the
install/fix via Bash. Pip-installable Python requirements are the exception:
install them automatically, then rerun preflight.

See `references/slurm-ssh-credentials.md` for the full preflight script, the
enroot-credentials heredoc, prerequisite key setup (keypair, `ssh-copy-id`,
`known_hosts`, container key mounts, 2FA handling), and the SSH failure
remediation prompt.

## Execution — the four verbs

`tao-run-on-slurm` is a platform **consumer**: it runs a spec-bundle over
`ssh + sbatch/squeue/sacct/scancel`, mutating only the job-record. Storage is
**tier A** (Lustre) — the dataset is staged to a shared path *before* submit and
read through Pyxis; never fetch S3 inside the allocation (the scheduler-idle
timeout kills GPU-idle jobs and bills the wasted time). `$BANK` =
```
