description

Launch the fixed Delphi #6279 RL-scaling-laws downstream MATH eval suite (MATH-500 / AIME24 / gsm8k via evalchemy + lm_eval) on CINECA Leonardo, for completed SFT / RL / base checkpoints. Covers finding which cells are newly-completed-but-uneval'd, the offline pre-download, the delphi_eval.sbatch invocation + RUN_NAME/STAGE convention, the load-bearing gotchas (chat-template override, 4k context, TP per head-count, MATH500/gsm8k split), and the SCORES.md tracker update. HF-upload-only — NEVER DB-register. Use when asked to eval Delphi #6279 SFT cells / update the scaling-laws score grid. Refs: experiments/active/delphi/rl-scaling-laws-6279/.

eval-standard-launch

Downstream math-eval harness for Delphi #6279 RL-scaling-laws (task #215) — NOT the agentic tb2 eval listener. Scores Delphi checkpoints on MATH-500 (1 seed) + AIME24 (10-seed mean±se) + gsm8k (strict+flex) via evalchemy/lm_eval on Leonardo. HF-upload only — NEVER DB-registered (project_delphi_sft_hf_only_no_db).

0. Reference files (read these first — they are the source of truth)

Local notes dir: /Users/benjaminfeuer/Documents/experiments/active/delphi/rl-scaling-laws-6279/

• EVAL_CONVENTION.md — the fixed eval protocol (suites, seeds, naming §3.4, chat-template §2.5).
• delphi_eval.sbatch — the ONE eval job (all gotchas baked in; canonical). Cluster copy under /leonardo_work/AIFAC_5C0_290/bfeuer00/….
• main_sft_evals/SCORES.md — master tracker for the 54-run main grid (27 midtrained ckpts × 2 cold-starts: magpie_lr1e5 math-strong / wc386k_lr1e5 math-weak). Each row: HF model laion/<basename>, eval-job column, status (✅ done / ⏳ pending). The separate earlier cold-start grid lives in coldstart_grid_evals/ (own ../eval/SCORES.md).
• SFT_LEONARDO_INSTRUCTIONS.md — the SFT side (how cells get trained + uploaded).

1. What "newly completed" means

A cell is ready to eval when its SFT model is uploaded to HF laion/<basename> (Delphi SFT is HF-only; an uploaded repo = a finished cell). The work = the SCORES.md rows still ⏳ pending whose laion/<basename> repo now exists + is non-empty (check via huggingface_hub/hf; HF_TOKEN from your secrets env — .agents/secret.md). Rows whose model isn't uploaded yet (e.g. most large 1e21/1e22 cells mid-training) are SKIPPED until done.

2. The launch (per cell)

# RUN_NAME = the exact SFT model basename; STAGE = sft (chat-template ON) | rl | base (template OFF)
RUN=delphi-9e19-p33m67-k0p20-lr83-a002-magpie_lr1e5-sft
sbatch --job-name="delphi-eval-$RUN" <leonardo>/delphi_eval.sbatch laion/$RUN $RUN sft

• Model-specific --job-name is MANDATORY (not the generic default) so squeue + %x-%j.log + meta.env map jobid→model 1:1. The script self-renames + emits a greppable EVAL_JOBMAP line + writes <OUT>/meta.env.
• Job shape: 1 node / 4 GPU (A100 64GB) / 8h / boost_usr_prod, conda env evalchemy-marin, runs from /leonardo_work/AIFAC_5C0_290/bfeuer00/code/evalchemy-marin. Output → …/experiments/delphi-eval/<RUN_NAME>/.

3. Pre-download is REQUIRED (compute is offline)

delphi_eval.sbatch runs HF_HUB_OFFLINE=1 (Leonardo compute has no internet). Pre-cache each model on the LOGIN node first into HF_HOME=HF_HUB_CACHE=/leonardo_work/AIFAC_5C0_290/bfeuer00/data/hub (login nodes have direct internet). If a login-node snapshot_download risks the ~100s login-killer, use the notes' documented pre-download path (tmux / a small sbatch). The eval sbatch itself needs NO SSH tunnel (offline + pre-cached); only the pre-download touches the network.

4. Load-bearing gotchas (all handled inside the sbatch — know them when debugging)

• HOME is read-only on Leonardo (login AND compute). The sbatch redirects HOME + flashinfer/triton/inductor/vLLM/XDG caches to a writable …/delphi-eval/.cache/*; without it every vLLM worker dies PermissionError … /.cache/flashinfer.
• delphi_v0 chat-template override (sft/rl only): the SFT/RL repos ship a plain 656-char Llama-3 template (the delphi ReasoningTemplate didn't persist into the repo) → evaluating as-is is a train/eval mismatch (empty think channel). The sbatch overrides the cached tokenizer's chat_template to OpenThoughts-Agent/chat_templates/delphi_v0.jinja2 (idempotent, leaves .plainbak) before eval. base stage skips this (no template, raw completion).
• MAX_MODEL_LEN=4096 (NOT the marin 32768 default): Delphi ckpts are 4k-cutoff with a malformed llama3 rope_scaling block; vLLM derives 4096 and HARD-rejects 32768. Generation pinned MAX_GEN_TOKS=3584. Comparability holds within the 4k cohort; flag any model exposing >4k.
• --max_tokens MUST be pinned to MAX_GEN_TOKS — MATH500/AIME24 are evalchemy chat_benchmarks whose max_new_tokens DEFAULTS to 32768 (not reached by --gen_kwargs max_gen_toks); unset → lm-eval computes 4096-32768 = negative → truncates prompt to empty → decoder prompt cannot be empty.
• TP per head-divisibility: num_attention_heads % TP == 0. The small Delphi Qwen3 (14 heads) → TP=2 (TP=4 hard-fails). Pin TP per model to the largest node-supported divisor of its head count.
• MATH500 and gsm8k run as SEPARATE sequential processes (not one --tasks call): MATH500 is an evalchemy chat_benchmark, gsm8k is lm-eval-native; in one process the second vLLM engine inits while the first is GPU-resident → OOM/WorkerProc fail and gsm8k is silently dropped. gsm8k runs via plain lm_eval (evalchemy double-builds the engine for native tasks → OOM on 64GB). AIME24 is its own pass.
• --verbosity INFO is required (evalchemy getattr(logging, args.verbosity); default None → AttributeError after full vLLM init).
• Idempotent skip: <OUT>/seed42 existing → the cell is skipped. If gsm8k failed after MATH500 wrote seed42, delete <OUT>/seed42 (or re-run gsm8k by hand) — the skip keys on that dir.

5. After submit → tracking + consolidation

1. Confirm queued: squeue -u bfeuer00 | grep delphi-eval; collect job ids.
2. Update main_sft_evals/SCORES.md: set submitted rows' status → 🚀 eval submitted + put the Leonardo job id in the eval-job column. Do NOT fabricate score cells (leave —); preserve the table format exactly.
3. On completion, per-model results_*.json rsync into main_sft_evals/<basename>/, scalar partials into main_sft_evals/.partial/<basename>.json, and SCORES.md is consolidated from them (MATH-500, AIME24 mean±se, gsm8k strict/flex, Raw). The #6279 deliverable = how MATH-500/AIME24/gsm8k move with (scale × mix) at each of the two starting points (does a strong-vs-weak math start change the midtraining ranking).

5b. Evaluate a (post-RL) checkpoint on the Delphi eval suite (reusable)

The same harness scores ANY standard Delphi checkpoint — base / post-SFT / post-RL — on the fixed suite (EVAL_CONVENTION.md §1.2: MATH500 1-seed + AIME24 10-seed mean±se + gsm8k strict/flex, pass@1, temp 0.7). rl-standard-job-cleanup defers to THIS section as its final step after the post-RL ckpt is HF-uploaded. The only deltas from §2 are the STAGE token and the tracker the result lands in:

1. Point it at the HF-uploaded ckpt. The ckpt is laion/<run_name>-<BEST>-<size>B (the repo rl-standard-job-cleanup §6 just published — weights at root). Pre-cache it on the login node first (§3), same as any cell.
2. STAGE = rl (chat-template ON — same delphi_v0 override as sft; only base skips it):

   RUN=<run_name>-<BEST>-<size>B
   sbatch --job-name="delphi-eval-$RUN" \
     /leonardo_work/AIFAC_5C0_290/bfeuer00/experiments/delphi-eval/delphi_eval.sbatch laion/$RUN $RUN rl
   

   Auto-TP=2 for the 30-head 9.7B Delphi Qwen3; max_model_len=4096/max_gen_toks=3584; all §4 gotchas (template override, 4k context, MATH500/gsm8k split, AIME24 10-seed pass) apply unchanged — baked into the canonical delphi_eval.sbatch. One node / 4 GPU / 8h / evalchemy-marin env.
3. Results land in the RL tracker, not the SFT one. Per-model output is …/experiments/delphi-eval/<RUN>/seed{42..51} + meta.env; consolidated scores go to main_rl_evals/SCORES.md (the post-RL tracker — keyed by (scale, mix, start-point) so SFT-vs-RL deltas line up against main_sft_evals/), via the same harvest path as §5 / eval-standard-cleanup. HF-upload-only — NEVER DB (the post-RL ckpt has no models DB row and this eval doesn't create one). After submit, add the row to main_rl_evals/SCORES.md set to 🚀 eval submitted with the Leonardo job id; harvest per eval-standard-cleanup.

6. Leonardo SSH quoting traps (these bite repeatedly)

• Do NOT use parentheses inside a bash -lc "..." double-quoted string.
• Do NOT use single quotes inside the outer ssh '...' arg (a single quote closes it). Use escaped double-quotes / heredocs / plain words.
• Refresh the step-ca cert if any tunnel op needs it (per CLAUDE.md) — but offline eval sbatch + a login-node pre-download (direct internet) do not need the tunnel.
• Don't disturb the still-PENDING Delphi SFT dependency chain; evals are independent 1-node jobs.
