Experiment Queue

⏱ External cadence: visibility only. This skill already runs its own detached server-side scheduler (60s poll + depends_on + wave transitions). Use its status output for overnight visibility (N done / N running / N pending); do not wrap it in a second /loop / CronCreate poll — that duplicates the scheduler on an uncoordinated clock and races the wave-transition logic it was built to prevent. See shared-references/external-cadence.md ("don't duplicate an existing scheduler").

Orchestrate large batches of ML experiments on SSH remote GPU servers with proper state tracking, OOM retry, stale cleanup, and wave transitions.

When to Use This Skill

Use when /run-experiment is insufficient:

≥10 jobs that need batching across GPUs
Multi-seed sweeps (e.g., 21 seeds × 12 cells)
Wave transitions (run wave 1, wait, run wave 2, wait, run wave 3...)
Teacher+student chains (train teacher then distill; auto-trigger student after teacher done)
OOM-prone configs where you need to retry with different GPU or wait
Mixed seed grids where failed cells need re-running

Do NOT use for:

Single ad-hoc experiment (use /run-experiment)
Modal/Vast.ai deployments (those have their own orchestration)
Experiments that need manual inspection between runs

Why This Exists

Based on session audit (2026-04-16), the major wall-clock sinks in multi-seed grid experiments are:

Stale screens — python finishes, wandb uploads, screen hangs, next wave blocked
OOM on shared GPU — previous job's memory not yet released
Wave race — new wave launches before previous wave fully settles
Missing checkpoints — student launches before teacher saved
Parser duplication — rewriting multi-seed analysis python every batch

All of these are pure engineering friction that can be orchestrated.

Core Concepts

Environment contract: queue jobs assume the target env is already built and validated per ../shared-references/compute-env-contract.md (spec-hash ledger + kernel witness). A wave of jobs dying at import time = the env contract was skipped, not a queue bug; check the provider's .aris/compute/<provider>.md ledger before re-queueing.

Job Manifest

A manifest lists jobs with explicit state:

project: my_grid_experiment
cwd: /home/user/your_project
conda: my_env
# Optional: override conda hook path if conda is not at a standard location.
# Can be a bare path (wrapped automatically) or a full `eval "$(... shell.bash hook)"` string.
# Falls back to auto-detect of ~/anaconda3, ~/miniconda3, /opt/anaconda3, etc.,
# or the ARIS_CONDA_HOOK environment variable.
# conda_hook: /custom/path/to/conda

  python run_distill.py --backbone softmax --lam 0.5
  --K 500 --L 96 --W 16 --n_steps 30000 --batch_size 128 --lr 1e-4

preconditions:
  - type: checkpoint_exists
    path: checkpoints/transformer/teacher_L96_K500_N{N}.pt

gpus: [0, 1, 2, 3, 4, 5, 6, 7]

  - id: s200_N128_n50K
    args: {seed: 200, n_hidden: 128, n_train_subset: 50000, subset_seed: 2024}
  # ... 14 more

Job State Machine

pending → running → completed
                 ↘ failed_oom → pending (after delay) [retry up to N]
                 ↘ failed_other → stuck (needs manual inspection)
stale screen (process gone, screen lingering) → failed_other → stuck

Operator note on stuck (the agent's move, not the queue's): the queue deterministically parks failed_other jobs as stuck — that part is code and unchanged. Before handing a stuck batch to the human, the OPERATING AGENT should check: if the same failure repeats across jobs, try ONE clean reimplement of the agent-generated wrapper/attempt script only — never user/project source (run_*.py you didn't write), the manifest, queue state, logs, or results (see shared-references/external-cadence.md § Let a broken attempt restart, not just patch). Reserve the human handoff for contract/environment doubts, not merely broken attempt code.

Wave Orchestration

A "wave" is a batch of jobs that fit available GPUs. Next wave only starts when:

All current-wave python processes have exited
No stale screens remain for current-wave tags
GPU memory has dropped below threshold (≤500 MiB)
Precondition checks pass for next-wave jobs

Workflow

Step 1: Parse Manifest / Build from Grid

Input can be:

YAML manifest (explicit job list, recommended for complex cases)
Grid spec (Cartesian product of param values, e.g., N=[64,128,256] × n=[50K,150K,500K,652K])
Natural language description (Claude parses into manifest)

Bind the run identifiers once so every later step (manifest save, scp, launch, monitor, resume) refers to the same paths. Set these as local shell variables before generating the manifest:

# REPLACE the placeholder path before running, or pre-export PROJECT_DIR:
PROJECT_DIR="${PROJECT_DIR:?set PROJECT_DIR to the local project root}"
RUN_TS=$(date -u +%Y%m%dT%H%M%SZ)             # one timestamp per run, reused everywhere
LOCAL_RUN_DIR="$PROJECT_DIR/experiment_queue/$RUN_TS"
mkdir -p "$LOCAL_RUN_DIR"

Save the built manifest to $LOCAL_RUN_DIR/manifest.json for reproducibility.

Step 2: Pre-flight

Check SSH connection works
Check conda env exists on remote
Check cwd exists on remote
Check all preconditions (checkpoints, input files)
Check GPU availability (at least max_parallel free GPUs)

If any precondition fails, show user which jobs are blocked and why.

Step 3: Launch Scheduler

The canonical scheduler implementation lives in skills/experiment-queue/scripts/queue_manager.py (Phase 3.3 move, Arch C). tools/experiment_queue/queue_manager.py is now a Python os.execv shim retained for legacy resolver-chain compatibility. Three preliminaries before launch.

3a. Resolve the local helper directory. The two helpers (queue_manager.py, build_manifest.py) now sit under skills/experiment-queue/scripts/ in the ARIS repo, with shims at tools/experiment_queue/ for legacy resolver layers. Use this hybrid chain so the skill works from any project layout:

# Layer 0: self-contained (CC 1.0+ exposes $CLAUDE_SKILL_DIR).
QUEUE_TOOLS=""
if [ -n "${CLAUDE_SKILL_DIR:-}" ] && [ -f "$CLAUDE_SKILL_DIR/scripts/queue_manager.py" ]; then
  QUEUE_TOOLS="$CLAUDE_SKILL_DIR/scripts"
fi
# Layers 1-4: legacy chain via tools/experiment_queue/ shims.
if [ -z "$QUEUE_TOOLS" ]; then
  cd "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" || exit 1
  if [ -z "${ARIS_REPO:-}" ] && [ -f .aris/installed-skills.txt ]; then
      ARIS_REPO=$(awk -F'\t' '$1=="repo_root"{print $2; exit}' .aris/installed-skills.txt 2>/dev/null) || true
  fi
  if [ -z "${ARIS_REPO:-}" ] && [ -f "$HOME/.aris/repo" ]; then
      ARIS_REPO=$(cat "$HOME/.aris/repo" 2>/dev/null) || true
  fi
  QUEUE_TOOLS=".aris/tools/experiment_queue"
  [ -f "$QUEUE_TOOLS/queue_manager.py" ] || QUEUE_TOOLS="tools/experiment_queue"
  [ -f "$QUEUE_TOOLS/queue_manager.py" ] || { [ -n "${ARIS_REPO:-}" ] && QUEUE_TOOLS="$ARIS_REPO/tools/experiment_queue"; }
  [ -f "$QUEUE_TOOLS/queue_manager.py" ] || QUEUE_TOOLS=""
fi
[ -z "$QUEUE_TOOLS" ] && { echo "ERROR: experiment_queue helpers not found (layer 0: \$CLAUDE_SKILL_DIR/scripts/; layers 1-4: .aris/tools/, tools/, \$ARIS_REPO/tools/, \$ARIS_REPO/tools/ via ~/.aris/repo). Rerun install_aris.sh or smart_update.sh (refreshes ~/.aris/repo), set ARIS_REPO, or copy the canonical scripts from \$ARIS_REPO/skills/experiment-queue/scripts/." >&2; exit 1; }

The .aris/tools symlink is set up by install_aris.sh (#174). Older installs without that symlink fall through to tools/experiment_queue (works if invoked from inside the ARIS repo), $ARIS_REPO/tools/experiment_queue, or the same path resolved via the global pointer file ~/.aris/repo (#366, for installs with no project-local manifest). After Phase 3.3, each of those legacy paths contains a Python os.execv shim that forwards to the canonical skills/experiment-queue/scripts/ location, so existing users do not need to re-run anything.

3b. Compute remote paths. Use both a remote-relative form (for scp destinations — modern scp runs in SFTP mode and does NOT reliably expand $HOME in destination paths) and a $HOME-prefixed form (for ssh ... command strings, where remote bash WILL expand $HOME):

REMOTE_RUN_REL=".aris_queue/runs/$RUN_TS"          # for scp destinations (relative to remote home)
REMOTE_RUN_DIR="\$HOME/$REMOTE_RUN_REL"            # for ssh command strings (literal $HOME, expanded on remote)

3c. Bootstrap the remote run directory and copy helpers + manifest. Per-invocation and idempotent. Use a unique run directory rather than /tmp so concurrent queues do not collide and so resume-after-crash is reproducible.

ssh <server> "mkdir -p \"$REMOTE_RUN_DIR/logs\" \"\$HOME/.aris_queue\""
scp "$QUEUE_TOOLS/queue_manager.py" "$QUEUE_TOOLS/build_manifest.py" <server>:.aris_queue/
scp "$LOCAL_RUN_DIR/manifest.json" <server>:"$REMOTE_RUN_REL/manifest.json"

3d. Launch the scheduler as a detached nohup process on the SSH host:

ssh <server> "nohup python3 \"\$HOME/.aris_queue/queue_manager.py\" \\
  --manifest \"$REMOTE_RUN_DIR/manifest.json\" \\
  --state    \"$REMOTE_RUN_DIR/queue_state.json\" \\
  --log-dir  \"$REMOTE_RUN_DIR/logs\" \\
  > \"$REMOTE_RUN_DIR/queue_mgr.log\" 2>&1 &"

Notes for callers:

--log-dir is what queue_manager.py actually consumes (per-job log files for OOM detection). Do NOT pass --log <path> — that flag is declared but unused, and a single combined log breaks the per-job stale-screen / OOM heuristics.
Persist RUN_TS / REMOTE_RUN_REL / REMOTE_RUN_DIR to disk so monitoring and resume can reload them without regenerating:
```
{
  printf 'PROJECT_DIR=%q\n'    "$PROJECT_DIR"
  printf 'RUN_TS=%q\n'         "$RUN_TS"
  printf 'LOCAL_RUN_DIR=%q\n'  "$LOCAL_RUN_DIR"
  printf 'REMOTE_RUN_REL=%q\n' "$REMOTE_RUN_REL"
  printf 'REMOTE_RUN_DIR=%q\n' "$REMOTE_RUN_DIR"
} > "$LOCAL_RUN_DIR/run_meta.txt"
```
%q shell-escapes the values so the file is safely sourceable later. Note that REMOTE_RUN_DIR keeps a literal $HOME (do not expand it locally), which is the right form for re-use inside ssh "..." strings later.

3e. Resume an existing queue (only when the user asks). A fresh RUN_TS per invocation is correct for new queues. To resume a crashed queue, do NOT regenerate RUN_TS — reload the recorded values and re-run only the launch command (Step 3d), not the bootstrap (Step 3c):

LOCAL_RUN_DIR="/abs/path/to/project/experiment_queue/<existing-run-ts>"   # the run dir to resume
. "$LOCAL_RUN_DIR/run_meta.txt"                                            # reloads PROJECT_DIR / RUN_TS / REMOTE_RUN_REL / REMOTE_RUN_DIR
# Then re-run Step 3d verbatim. Do NOT re-run Step 3c (would overwrite manifest.json + state.json).

Orchestrate large batches of ML experiments on SSH remote GPU servers with proper state tracking, OOM retry, stale cleanup, and wave transitions.

## When to Use This Skill

- **OOM-prone configs** where you need to retry with different GPU or wait
- **Mixed seed grids** where failed cells need re-running

Do NOT use for:
