Hyperloom Qwen3 14b Fp8 12h Forge

Hyperloom Qwen3-14B-FP8 12h Run (Forge Kernel Backend)

Read .env first and resolve HYPERLOOM_SKILL_PATH. Read and follow the optimizer skill at @${HYPERLOOM_SKILL_PATH} before launching. If HYPERLOOM_SKILL_PATH is missing, fall back to @hyperloom/inference_optimizer/SKILL.md (wheel install) or @src/hyperloom/inference_optimizer/SKILL.md (source checkout). This skill provides the concrete workload and launch constraints for a 12-hour Qwen3-14B-FP8 demo.

This is the hyperloom-qwen3-14b-fp8-12h demo with one difference: the KERNEL_AGENT phase runs the per-kernel KernelForge backend instead of GEAK. The workload, budget, and phase split are identical on purpose, so the two runs stay directly comparable.

Kernel Backend

Set KERNEL_OPT_BACKEND_ORDER=forge in the environment that launches optimize. This is the only switch: the opt-in is an exact match on forge, and every other value (including unset) leaves GEAK owning the whole kernel phase.

export KERNEL_OPT_BACKEND_ORDER=forge

Nothing else has to be installed or configured for this:

• KernelForge is vendored into Hyperloom. There is no repository to clone and no FORGE_PATH to point anywhere.
• The runtime installer already installs the claude CLI that the forge backend drives, unconditionally — the backend is chosen per session, later.
• Forge reuses the LLM credentials setup already wrote. It reads CLAUDE_MODEL / CODEX_MODEL, the same pair every other Hyperloom component reads, so no separate key or model id is needed.
• rocprof-compute profiling deps are installed unconditionally too.

Do not set the other FORGE_* variables. They are internal tuning knobs with working defaults; overriding them is not part of this demo.

Write the value into .env as well when the user wants it to persist across runs, so a --resume-from relaunch keeps the same backend:

KERNEL_OPT_BACKEND_ORDER=forge

Before launch, confirm the value is actually set in the launching shell and report it. Launching without it silently runs GEAK and produces a run that looks like this demo but is not.

Run Mode

Resolve the run mode before launching Hyperloom:

1. If HYPERLOOM_RUN_MODE=baremetal or it is unset, run this demo directly on the host.
2. If HYPERLOOM_RUN_MODE=docker, this skill owns the Docker setup. Ask the user whether they want a vllm or sglang Docker image unless HYPERLOOM_IMAGE is already set. Use a ROCm image that already contains the selected framework; do not install the framework inside Docker.

In docker mode:

• If hyperloom-setup already ran, do not re-run setup on the host.
• Read HYPERLOOM_DOCKER_TARGET_HOST from .env when present. If it names a host different from $(hostname), first SSH to that host and continue this Docker setup there; do not start Docker on the login/current host.
• Always run setup inside the container after docker run.
• Pass --install-framework none --yes in the container (ROCm/framework comes from the image). Do not use --skip-base-check — let Phase 1 preflight validate the container environment.
• Do not run python -m hyperloom.inference_optimizer.cli optimize on the host.
• KERNEL_OPT_BACKEND_ORDER=forge must be set inside the container, in the same docker exec that launches optimize. Exporting it only on the host does not reach the optimizer.

Prior workload cleanup (required)

Before any replacement launch after a failed or abandoned demo run (docker run, install.sh, or a new/fresh optimize), follow IR-1 — Prior workload cleanup gate in @${HYPERLOOM_SKILL_PATH}. Run all probes on the docker host; never skip the user-approval step (#1314).

Suggested Docker images:

• vllm: docker.io/vllm/vllm-openai-rocm:v0.27.1
• sglang MI300X: docker.io/lmsysorg/sglang-rocm:v0.5.18-rocm724-mi30x-20260825
• sglang MI355X: docker.io/lmsysorg/sglang-rocm:v0.5.18-rocm724-mi35x-20260825

In Docker mode, start a long-running container on HYPERLOOM_DOCKER_TARGET_HOST (or the current host when it is unset) before running setup or optimize:

export REPO_ROOT="$(pwd -P)"
docker run -d \
  --name "${HYPERLOOM_CONTAINER_NAME:-hyperloom-local}" \
  --shm-size "${HYPERLOOM_SHM_SIZE:-64g}" \
  --entrypoint tail \
  --device /dev/kfd \
  --device /dev/dri \
  --group-add video \
  -v "$REPO_ROOT:$REPO_ROOT" \
  "$HYPERLOOM_IMAGE" \
  -f /dev/null

Mount the Hyperloom workspace at the same absolute path (-v "$REPO_ROOT:$REPO_ROOT") so paths in .env, logs, and session artifacts stay valid. If USER_DATA_PATH or a pre-downloaded model directory is outside the workspace, add matching -v host_path:host_path mounts before starting the container.

Then run the setup backend inside the container:

docker exec -w "$REPO_ROOT" "${HYPERLOOM_CONTAINER_NAME:-hyperloom-local}" bash -lc \
  'REPO_ROOT="$(pwd -P)"; PYTHONPATH="$REPO_ROOT" python3 -m hyperloom.inference_optimizer.setup -- --install-framework none --yes'

After that, run all remaining commands for this demo inside the same container with docker exec -w "$REPO_ROOT" ...; do not run python -m hyperloom.inference_optimizer.cli optimize on the host in Docker mode. When the demo is finished, ask the user whether to stop the container. If they say yes, run:

docker stop "${HYPERLOOM_CONTAINER_NAME:-hyperloom-local}"

Environment

• MODEL_PATH=<optional; if unset, download Qwen/Qwen3-14B-FP8 from Hugging Face with the Python steps below, then set MODEL_PATH to that local path>
• FRAMEWORK=<provided by the existing environment or repository-root .env; do not invent it>
• GPU_TYPE=<do not set; omit --gpu-type and let Hyperloom auto-detect from ROCm/system info>
• KERNEL_OPT_BACKEND_ORDER=forge (required by this demo; see Kernel Backend)

Required optimize CLI flags:

• --tp 1
• --conc 64
• --isl 1024
• --osl 1024
• --precision fp8
• --target-gain 50
• --max-hours 12
• --max-minutes-framework-pct 0.43
• --max-minutes-kernel-pct 0.42

There is no CLI flag for the kernel backend — it is selected by the environment variable only. Do not invent one.

Before launch, read the repository-root .env file if it exists and load the needed environment variables from it, such as LLM API keys/base URLs, FRAMEWORK, and HF_TOKEN. Do not copy secret values into the prompt, terminal output, reports, or logs. Do not modify USER_DATA_PATH.

Before resolving or downloading any model, always ask the user which model path to use. Present the currently resolved option when MODEL_PATH is already set, and always offer a custom local path plus the demo default. Do not continue until the user chooses one.

Use this decision flow:

• If the user chooses the existing MODEL_PATH, inspect that path and use it only when it contains config.json; otherwise ask again for a valid path or the demo default.
• If the user provides a custom local path, export MODEL_PATH to that path and require config.json before launch.
• If the user chooses the demo default, set MODEL_PATH=${REPO_ROOT}/.cache/hyperloom-models/Qwen3-14B-FP8 and download Qwen/Qwen3-14B-FP8 there when config.json is not already present.

Do not assume the Hugging Face CLI exists; resolve or download the selected model with Python:

python -m pip install -U huggingface_hub
export REPO_ROOT="$(pwd -P)"
export MODEL_PATH="${MODEL_PATH:-${REPO_ROOT}/.cache/hyperloom-models/Qwen3-14B-FP8}"
python - <<'PY'
import os
from pathlib import Path
from huggingface_hub import snapshot_download

target = Path(os.environ["MODEL_PATH"]).expanduser()
if (target / "config.json").is_file():
    print(f"Using existing model at {target.resolve()}")
else:
    snapshot_download(
        repo_id="Qwen/Qwen3-14B-FP8",
        local_dir=str(target),
    )
print(target.resolve())
PY

Pre-launch Runtime Install

Before the first optimize launch, run the full runtime installer in the same environment that will launch the optimizer. Preflight loads kernel-agent.env.sh before it can reach the later Ray/Magpie/InferenceX auto-install checks, so this step must happen before launching.

For Docker mode, run this inside the container. For bare-metal mode, run it on the host:

export REPO_ROOT="$(pwd -P)"
# .env fills gaps only: re-exporting the non-empty pre-source snapshot keeps every
# value the caller exported. Wider than install.sh, which guards a fixed list.
_dotenv_prev="$(export -p | grep -v -e '=""$' -e "=''\$")"
set -a; . "${REPO_ROOT}/.env"; set +a
eval "$_dotenv_prev"
unset _dotenv_prev
export USER_DATA_PATH="${USER_DATA_PATH:?USER_DATA_PATH missing}"
export PYTHONPATH="${REPO_ROOT}:${PYTHONPATH:-}"
ulimit -Sn 65536 || true
INSTALL_SH="${REPO_ROOT}/hyperloom/inference_optimizer/assets/install.sh"
if [ ! -f "$INSTALL_SH" ]; then
  INSTALL_SH="${REPO_ROOT}/src/hyperloom/inference_optimizer/assets/install.sh"
fi
bash "$INSTALL_SH"
. "$USER_DATA_PATH/runtime/kernel-agent.env.sh"
export PYTHONPATH="${REPO_ROOT}:${PYTHONPATH:-}"

If hyperloom/inference_optimizer/assets/install.sh is not present (source checkout layout), use src/hyperloom/inference_optimizer/assets/install.sh.

Sourcing .env in the block above sets KERNEL_OPT_BACKEND_ORDER to whatever the file carries, and eval "$_dotenv_prev" then replays the caller's pre-existing exports on top of it. Either value can win, so export forge after this block, and verify it right before launching:

export KERNEL_OPT_BACKEND_ORDER=forge
echo "kernel backend: ${KERNEL_OPT_BACKEND_ORDER}"

User-visible Progress

Keep the user informed with concise status updates throughout the demo. Do not dump full debug logs into chat; report the important values and paths so the user can tell that work is progressing.

Before launch, report the launch plan:

• model path and whether it is an existing local model or a downloaded default;
• run mode (baremetal or docker) and target host/container when applicable;
• framework, TP, concurrency, ISL, OSL, precision, max hours, and required demo flags;
• the resolved kernel backend (KERNEL_OPT_BACKEND_ORDER);
• USER_DATA_PATH and where runtime artifacts will be written.

After the runtime install, report whether it succeeded and the path to kernel-agent.env.sh. After starting the optimizer, report:

• optimizer PID;
• run log path;
• launch-info JSON path;
• resolved session directory;
• state.json path;
• initial health check result.

Confirm the backend actually took effect rather than assuming it did. The optimizer records the resolved choice as kernel_optimizer in the session state.json, which is geak unless the env var opted in:

grep -o '"kernel_optimizer": *"[^"]*"' "$SESSION_DIR/state.json"

Check this right after launch and report the value. If it is geak, stop and tell the user the environment variable did not reach the optimizer, instead of letting a 12-hour run continue as an unlabelled GEAK run.

During monitoring, print a short summary at each 300-second check:

• process alive/stopped;
• phase and stop_reason;
• baseline throughput, current best throughput, and cumulative gain when present;
• latest benchmark result or candidate decision when available;
• the most relevant recent log lines, excluding secrets.

When the run finishes, report the final status, final report path, best result, and the stop reason. Never print API keys, tokens, or custom header values.

Launch Requirements

1. Run the pre-launch runtime install above and source $USER_DATA_PATH/runtime/kernel-agent.env.sh before launching.
2. Export KERNEL_OPT_BACKEND_ORDER=forge in the launching shell, after sourcing kernel-agent.env.sh, and confirm the value before launch. In docker mode, set it inside the same docker exec that runs optimize.
3. Keep PYTHONPATH="$REPO_ROOT:${PYTHONPATH:-}" in the launch shell so robustness and critic subprocesses can import hyperloom.agents after changing cwd.
4. Run in background with setsid nohup.
5. Pass all required optimize CLI flags in the python -m hyperloom.inference_optimizer.cli optimize command. Do not rely on .env alone for TP, CONC, ISL, OSL, or PRECISION; CLI defaults can otherwise override the intended workload.
6. Include --max-minutes-framework-pct 0.43 and --max-minutes-kernel-pct 0.42 in the optimize command. Do not pass --no-framework-agent or --no-kernel — this demo runs the full OPTIMIZE phase (FRAMEWORK_AGENT + KERNEL_AGENT), and --no-kernel would skip the very phase this demo exists to exercise.
7. Report the session ID, log path, PID, and initial health check result.
8. Monitor the process every 300 seconds until work is done.
9. To recover an unexpected crash, only run optimize --resume-from "$SESSION_DIR" against the same session dir, with KERNEL_OPT_BACKEND_ORDER=forge still set. After the first launch, never start a new optimize; that creates a new <UTC_ts> session and is forbidden.
10. If stop_reason in the current session state.json is final, stop and exit.
