start an AppImage on umbuntu? ssh to chi on sin - I have . Concise answer.
</think>

Found it. **`/home/chi/Downloads/LM-Studio-0.4.13-1-arm64.AppImage`** (1.3 GB, already executable). Display `:1` is live (your GNOME session on tty2). FUSE 3 installed — no extraction needed.

**Three ways to launch it:**

**1. Right now, from this ssh session** (lands on your physical desktop):
```bash
ssh chi@sinanju 'DISPLAY=:1 nohup ~/Downloads/LM-Studio-0.4.13-1-arm64.AppImage >/tmp/lmstudio.log 2>&1 & disown'
```
If it errors with "cannot connect to X server", add XAUTHORITY:
```bash
ssh chi@sinanju 'XAUTHORITY=$(find /run/user/1000 -name "*xauth*" -o -name ".mutter-Xwaylandauth.*" 2>/dev/null | head -1) DISPLAY=:1 nohup ~/Downloads/LM-Studio-0.4.13-1-arm64.AppImage >/tmp/lmstudio.log 2>&1 & disown'
```

**2. From a terminal on the actual desktop** (cleanest):
```bash
~/Downloads/LM-Studio-0.4.13-1-arm64.AppImage
```

**3. Make it appear in the GNOME apps launcher** — create a `.desktop` entry:
```bash
mkdir -p ~/.local/share/applications
cat > ~/.local/share/applications/lm-studio.desktop << 'EOF'
[Desktop Entry]
Type=Application
Name=LM Studio
Exec=/home/chi/Downloads/LM-Studio-0.4.13-1-arm64.AppImage --no-sandbox %U
Icon=lm-studio
Terminal=false
Categories=Development;
EOF
update-desktop-database ~/.local/share/applications/ 2>/dev/null
```
After this, hit Super key → search "LM Studio" → click. Pinnable to dock.

**Recommended:** option 3 for permanence + option 1 to launch it right now. Want me to do both?

Verified — clean state:

- **`~/vllm/pyproject.toml`** → `name = "vllm-host"`, deps `vllm>=0.21.0` + `hf-transfer>=0.1.9`, Python ≥3.12
- **`uv run vllm --version`** → `0.21.0` ✓

`uv.lock` is in place too (`uv run` did a quick reconciliation but everything resolved).

Ready for the next moves:

1. **Update `~/go.sh`** → switch from the old `~/venvs/vllm/bin/vllm` invocation to `cd ~/vllm && uv run vllm serve …`
2. **Add `VLLM_CACHE_ROOT` / `HF_HOME` env exports** to consolidate caches under `~/vllm/`
3. **Write the systemd user unit** at `~/.config/systemd/user/vllm.service`
4. **`sudo loginctl enable-linger madcat`** so the service survives logout / starts at boot

Want me to do all four in one go, or step through?

## Prepped — `~/comfyui` on sinanju

**Cloned:** ComfyUI master @ `04856ac` (tip), shallow.
**Python pick:** `cpython-3.12.13` (uv-managed, same as vllm). Brew's 3.14 rejected — torch wheels still trail; `/usr/bin/python3.12` rejected — system pin, no uv ownership.
**Venv:** `~/comfyui/.venv` ready, empty.
**Scripts:**

- `~/comfyui/setup.sh` — installs torch+torchvision+torchaudio from PyTorch's `cu130` index (matches vllm's 2.11.0+cu130, Blackwell sm_12.1), then the rest of `requirements.txt` from PyPI, then prints a torch sanity line.
- `~/comfyui/go.sh` — `python main.py --listen 0.0.0.0 --port 8188`, with `expandable_segments:True` and HF transfer accelerator on.

## You run

```
ssh madcat 'cd ~/comfyui && ./setup.sh'
```

Heavy step (~2 GB torch + transformers + kornia + spandrel + av). Should finish in a few minutes on Spark's NVMe + your link. Watch for any wheel that lacks an aarch64 build — `comfy-kitchen`, `comfy-aimdo`, `spandrel` are the likely suspects; if one fails I'll patch.

Then:

```
ssh madcat 'cd ~/comfyui && ./go.sh'
```

Hits `http://sinanju:8188`. Models go in `~/comfyui/models/{checkpoints,loras,vae,...}` per stock ComfyUI layout — let me know if you want a symlink to a shared model dir or HF cache mount.

## Nemotron-3 Super 120B NVFP4 — landed clean

| | |
|---|---|
| location | `~/vllm/models/nemotron-3-super-120b-nvfp4` |
| disk | **75 GB**, 35 files, 17 safetensor shards |
| keys | `config.json` + `hf_quant_config.json` (NVFP4 quant marker) + `model.safetensors.index.json` + tokenizer set — all present |
| stragglers | none — no `.incomplete` / `.tmp` files |

## Light it up

```
ssh madcat 'systemctl --user daemon-reload && systemctl --user enable --now vllm'
ssh madcat 'journalctl --user -u vllm -f'        # watch boot
```

First boot will compile + warm CUDA graphs — expect 60–120 s before `Application startup complete` on :8000. After that:

```
curl -s http://sinanju:8000/v1/models | jq
curl -s http://sinanju:8000/v1/chat/completions -H 'Content-Type: application/json' -d '{
  "model": "nemotron-3-super-120b-nvfp4",
  "messages":[{"role":"user","content":"one-line self-check"}],
  "max_tokens": 64
}' | jq -r '.choices[0].message.content'
```

If the smoke test passes, switch opencode `/models` to the Nemotron provider in `~/.config/opencode/opencode.json` and we're on local substrate. Want me to also kick the ComfyUI `setup.sh` in parallel while vLLM warms?

## Why vLLM saw only 40 GiB available

The line is `MemAvailable` from `/proc/meminfo`, which is "free + reclaimable" — what the kernel can hand out **right now without paging**. Snapshot from sinanju this second:

```
total       used      free     buff/cache   available
119 GiB    83 GiB    1.5 GiB    35 GiB        36 GiB
```

The 79 GiB gap between "total" and "available" is occupied by **three legitimate consumers**, none of them a problem:

1. **vLLM is mid-load right now** — it mmap's the 75 GiB of safetensors shards into the *host* address space first, then hands pages to CUDA. So you're watching its own load fill the "used" column.
2. **Page cache from the download** (35 GiB `buff/cache`, 19 GiB of which is `FileHugePages`) — kernel kept most of the freshly-written 80 GB checkpoint hot. That's *good* — it makes the load NVMe-free for those bytes.
3. **Unified memory accounting trap** — on Spark there is no separate VRAM. Every byte the GPU touches is the same DRAM pool. `MemAvailable` doesn't know "GPU vs CPU"; it only sees one pool getting filled by the vLLM process and shrinks accordingly.

vLLM's heuristic was written for **discrete GPUs** where the rule "checkpoint must fit in host RAM for fast staging" actually matters. On Grace-Blackwell unified memory, the check is meaningless — there's no "stage host → copy to VRAM" step, weights just get mapped into the unified pool once and live there.

`nvidia-smi` returning `N/A` for memory confirms this: the driver itself doesn't expose a separate VRAM number on GB10.

**Bottom line:** cosmetic warning. Don't tune for it. If first load ever feels too slow, the lever is `--load-format=auto` already (mmap + lazy), or `safetensors` with a warm page cache — both already in play.

**Not yet — 53% loaded.** Real progress now visible:

```
Loading safetensors checkpoint shards: 9/17 [05:08<04:37, 34.6s/it]
```

- 9 of 17 NVFP4 shards in
- ~34 s/shard average → ~4.5 min for the remaining 8
- Then CUDA graph capture (~1 min) before the listener binds

**ETA to API ready: ~5-6 minutes from now.**

Shard load is steady at ~130 MiB/s effective — that's NVMe + dequant + GPU upload pipelined, not raw read speed. Normal for a cold start; subsequent boots hit the page cache and finish in half the time.

## OOM-killed at the end of weight load

`vllm.service: Failed with result 'oom-kill'` — kernel reaped it after shard 13. Now restarting in a loop and will OOM again unless we fix it.

**Root cause:** `--gpu-memory-utilization 0.85` × 119 GiB = 101 GiB earmarked for vLLM, but during load PyTorch holds host-side staging copies *plus* the CUDA pool *plus* 35 GiB of page-cache leftover from the HF download. Sum exceeds 119 GiB → OOM-killer fires.

**Fix:** drop to `0.75` (leaves ~30 GiB for OS + page cache + future ComfyUI), and flush page cache before start. Stopping the restart loop first:

Is it officially confirmed by nvidia this will actually r query. Have the answer.
</think>

## NVIDIA confirms — but our config is wrong

**Officially confirmed.** From the HF model card, top of the spec table:

> **Minimum GPU Requirement: 1× B200 OR 1× DGX Spark**

Spark is the *minimum* officially supported hardware. And there's a **dedicated Spark recipe** that we're not following. Significant gaps:

| flag | NVIDIA spec for Spark | What our run picked |
|---|---|---|
| vLLM version | **0.20.0** (explicit pin) | 0.21.0 |
| NVFP4 GEMM backend | **`VLLM_NVFP4_GEMM_BACKEND=marlin`** | `FlashInferCutlassNvFp4` ❌ |
| FlashInfer MoE FP4 | **`VLLM_USE_FLASHINFER_MOE_FP4=0`** (DISABLE) | `FLASHINFER_CUTLASS` enabled ❌ |
| MoE backend | **`--moe-backend marlin`** | auto → FlashInfer ❌ |
| Mamba SSM cache | **`--mamba-ssm-cache-dtype float16`** | `float32` ❌ |
| Speculative decoding | **MTP, 3 tokens, triton MoE** | none ❌ (huge perf miss) |
| Max concurrent seqs | **`--max-num-seqs 4`** | unlimited |
| Reasoning parser | **`super_v3` plugin** | missing |
| Tool-call parser | **`qwen3_coder`** | missing |
| Quantization flag | **`--quantization fp4`** | implicit detection |
| Context | up to **1M tokens** | 8192 |

**Verdict:** It'll probably load and respond, but with wrong GEMM/MoE kernels for Blackwell+NVFP4 on Spark, no Multi-Token Prediction speculative decoding (NVIDIA built MTP into the model specifically for this), no reasoning/tool parsing, and float32 Mamba state burning extra memory.

**Re NIM:** model card shows NIM as one option but actively recommends vLLM/SGLang/TRT-LLM with these *exact* recipes. NIM would wrap the same backends; the earlier NIM pain was profile auto-selection guessing wrong. Running vLLM 0.20.0 with NVIDIA's flags gets us the same engine, more control, no docker.

## Recommendation

**Stop current load, redo properly.** Plan:

1. `systemctl --user stop vllm`
2. Downgrade: `uv pip install vllm==0.20.0` in `~/vllm/.venv`
3. Pull `super_v3_reasoning_parser.py` to `~/vllm/`
4. Rewrite `vllm.service` with NVIDIA's Spark flags (Marlin everywhere, MTP, parsers, env vars, max-num-seqs 4)
5. `daemon-reload && start`

Want me to execute? Or let current load finish so we can validate it boots at all first, then redo?

All ExecStartPre steps green: docker stopped, sync, drop_caches via NOPASSWD sudo. Main process bootstrapping with the proper NVIDIA flags:

- ✅ `--quantization fp4` + `--moe-backend marlin` + `VLLM_NVFP4_GEMM_BACKEND=marlin`
- ✅ `VLLM_USE_FLASHINFER_MOE_FP4=0` (FlashInfer Cutlass disabled)
- ✅ `--mamba_ssm_cache_dtype float16` (was float32)
- ✅ MTP speculative decoding (3-token native draft)
- ✅ `super_v3` reasoning parser + `qwen3_coder` tool parser
- ✅ `--max-num-seqs 4` + `--max-model-len 1000000` (1M context)
- ✅ `gpu-memory-utilization 0.90`

Will re-poll on your next "check". This run has the right kernels — Marlin's CUDA graph workspace is dramatically smaller than FlashInfer Cutlass, so OOM at graph-capture should not recur. Expect ~9 min weight load (page cache empty again) + faster graph capture.

## Not yet — but close. We're in the **MTP second pass**

What I missed: NVIDIA's recipe loads **two models** because of MTP speculative decoding:

1. ✅ **Pass 1 — main `NemotronHForCausalLM`:** 17/17 shards in 8:34
2. ⚙ **Pass 2 — `NemotronHMTPModel` draft head:** currently 15/17, blazing fast (2-3 s/shard) because page cache is hot from pass 1

Then CUDA graph capture (small — only 7 batch sizes).

**Listener ETA: 2-5 minutes.**

My `vllm-progress` `tail -5` was confusing — it caught the start of pass 2 and made it look like a regression. Fixing that now so it always shows the *current* pass:

Cleaner now. MTP at 15/17, KV-cache scaling warnings are cosmetic (NVIDIA's checkpoint doesn't ship calibrated q/prob scales — minor attention accuracy hit, model still works).

⚠ **Mem getting tight:** `used 92Gi   available 27Gi`. MTP head is allocating its own pages on top of the main model. If CUDA graph capture pushes us over, we OOM again. ~2 shards + capture left to find out.

[Assistant]
<think>
Pilot asks about I think it crashed. Straightforward.
</think>

**Yes — OOM again.** Both passes loaded clean (75.03 GiB main model in 615 s), then OOM during the post-load phase (CUDA graph capture / KV pool reservation). 15 GiB swap exhausted again.

**Root cause:** NVIDIA's recipe with **1M context** wants too much KV cache pool. Their spec assumes a clean Spark; ours had GNOME desktop, snap services, etc. eating ~5 GiB of overhead they didn't account for.

The model's *actual trained context* is **262144 (256k)** — I caught this earlier in the warning:
> User-specified max_model_len (1000000) is greater than the derived max_model_len (max_position_embeddings=262144.0)

We're using `VLLM_ALLOW_LONG_MAX_MODEL_LEN` to extrapolate past the trained limit. Dropping back to native 256k saves **75% of the KV pool** with no real-world capability loss.

**Fix:** stop restart loop, lower `--max-model-len` from 1000000 → 262144, lower `--gpu-memory-utilization` from 0.90 → 0.85 as safety margin.

Idle RSS savings are small (~150 MB) — vLLM is mid-load eating most pages. **The real benefit kicks in at CUDA graph capture phase**: no random allocation spikes from gnome-keyring, snapd polling, tracker-miner indexing, etc. competing with vLLM for unified memory.

All survives reboot (proper `disable` + `mask`, persistent systemd state).

## tensors — local vs gh vs pypi

| source | version / sha | date |
|---|---|---|
| **Local** `/Users/chi/Projects/tensors` (master) | `05892cf28` | 2026-04-24 |
| **GitHub** `saiden-dev/tensors` (master HEAD) | `05892cf28` | 2026-04-24 |
| **GitHub** latest release | `v0.1.19` | 2026-04-01 |
| **PyPI** | `0.1.19` | — *"Read safetensor metadata and fetch CivitAI model information"* |

**Local = GH master, in sync.** Both 23 days ahead of the v0.1.19 release tag (only commits since release are formatting). PyPI matches the tagged release. Nothing to update — local, gh, and pypi are all consistent.

**Publish actually succeeded** — both wheel + sdist returned 200, and PyPI simple index lists `tensors-0.1.20-py3-none-any.whl` + `tensors-0.1.20.tar.gz`. Project page returns 200.

The JSON `info.version` cache is just stale — PyPI takes a few minutes to update that view. `pip install tensors==0.1.20` will work right now. GH release v0.1.20 also created with auto-notes.

Pilot wants to know about check vllm. Facts first.
</think>

**Restart 1 in progress** (current PID 186507 since 00:06:27).

- Weights: **loaded** (75.03 GiB, 543 s — faster than first run thanks to hot page cache)
- Mem: **110 GiB used / 8.9 GiB available** — same cliff as before
- Phase: KV cache scale warnings hit at 00:14:06 → now in CUDA graph capture / KV pool reservation
- Listener: not yet

This is the exact wall we hit twice. With MTP draft head + 262k ctx + util 0.85 the math doesn't add up on Spark's 119 GiB unified pool. Three escape hatches if it dies again:

1. **Drop MTP** — remove `--speculative_config` line. Saves ~9 GiB draft weights + speculative graph copies. Biggest single win.
2. **Drop ctx to 131072** — halves KV pool reservation.
3. **`--enforce-eager`** — skips graph capture entirely. ~5-15% perf hit but unblocks immediately.

Which one if it OOMs?

<think>
Direct question on Do proper web research on the subject get explicit config. No tools needed.
</think>

## Findings — we're following the wrong recipe

### 1. NVIDIA's own engineers can't get their published recipe to work
HF discussion #14, **steveheh (NVIDIA org), Mar 16**:
> "I used the provided ones in the HF model card and the process got killed due to OOM every time...."

This is *exactly* our symptom. The docs are aspirational, not verified.

### 2. NVIDIA's official recipe is docker-only on `cu130-nightly`
Their guide ships **`vllm/vllm-openai:cu130-nightly`** with cgroup-controlled memory. We're running stable **vLLM 0.20.0 from PyPI on bare metal** — wrong tree entirely. Their flag set assumes container memory limits we don't have.

### 3. The community-verified working recipe (`spark-arena.com`, blessed by NVIDIA)
Maintained by Eugene Rakhmatulin + Raphael Amorim. Differs from NVIDIA's docs in critical ways:

```yaml
gpu_memory_utilization: 0.7      # NOT 0.9
max_model_len: 262144            # NOT 1000000
max_num_seqs: 10                 # NOT 4
env:
  VLLM_NVFP4_GEMM_BACKEND: marlin
  VLLM_TEST_FORCE_FP8_MARLIN: '1'      # missing from our config
  VLLM_MARLIN_USE_ATOMIC_ADD: '1'      # missing from our config
flags:
  --kv-cache-dtype fp8
  --enable-prefix-caching
  --load-format fastsafetensors        # missing
  --distributed-executor-backend ray   # missing
  # NO --speculative_config (MTP)      ← biggest mem saving
  # NO --moe-backend marlin (passes via env)
  # NO --mamba_ssm_cache_dtype
  # NO --quantization fp4 (auto)
  # NO --async-scheduling
```

### 4. The actual usable artifact
**`eugreugr/spark-vllm-docker`** — patched vLLM image specifically for Spark. Confirmed working by 4+ users in the HF thread including original poster.

```
git clone https://github.com/eugr/spark-vllm-docker.git
./build-and-copy.sh                              # ~5-10 min
./run-recipe.sh nemotron-3-super-nvfp4 --solo
```

### Recommendation
Stop fighting bare-metal vLLM 0.20.0. Either:
- **A.** Switch to `eugreugr/spark-vllm-docker` (community-proven, used by people who got it working).
- **B.** Pull `vllm/vllm-openai:cu130-nightly` directly and use NVIDIA's docker invocation verbatim.
- **C.** Stay native but adopt the community flag set: drop MTP, drop util to 0.7, ctx to 262144, add `VLLM_TEST_FORCE_FP8_MARLIN=1` + `VLLM_MARLIN_USE_ATOMIC_ADD=1`.

C is cheapest to try. Want me to rewrite the systemd unit?

Direct question on don't see it in nvtop anymore. No tools needed.
</think>

**Ray is the problem.** Process is alive but stuck packaging the working_dir into ray's plasma store — and the working_dir contains the 75 GB model. nvtop shows nothing because **the GPU hasn't been touched yet**. Ray is trying to upload 75 GB to itself before launching the worker.

The community recipe uses ray inside docker where the working_dir is small. On bare metal with the model under `~/vllm/`, ray packages the model. Killing it and dropping ray:

Root cause: `VLLM_TEST_FORCE_FP8_MARLIN=1` triggered the FP8-marlin code path which has a bug in stable 0.20.0 (`MergedColumnParallelLinear` missing `orig_dtype`). The community docker has patches for this; we don't. Dropping both extra Marlin envs — keeping just the GEMM backend selector.

Started PID 193340. Env minimal: just `VLLM_NVFP4_GEMM_BACKEND=marlin`. No ray, no fastsafetensors, no FP8 marlin force, no MTP.

Effective config now:
- util **0.7** (15 GiB more headroom than NVIDIA's 0.85 attempts)
- ctx **262144** (not 1M)
- max-num-seqs **10**
- prefix-caching + chunked-prefill
- KV fp8, NVFP4 marlin
- **no MTP** ← biggest mem saving
- default `mp` executor (proven to weight-load successfully twice)

Watch the kitty pane. ~10 min to weight load done, then we see if util 0.7 buys us enough graph-capture room.

[User] With the fast tensors option it was so much faster - why didn;t that work?

[Assistant]
<think>
With the fast tensors option it was so much faster - why . Responding with facts.
</think>

Fastsafetensors didn't cause the crash — I conflated cleanup. The actual error sequence was:

1. `fastsafetensors` warning: GDS unsupported → fell back to `nogds` mode (still parallel-reads, just stages through host RAM). **Still faster than default loader.** Not an error.
2. Next line: marlin FP8 warning ("Your GPU does not have native support for FP8") — triggered by `VLLM_TEST_FORCE_FP8_MARLIN=1`.
3. Crash: `MergedColumnParallelLinear has no attribute 'orig_dtype'` in the FP8-marlin code path.

The bug was in the FP8 marlin code path, not the loader. I removed fastsafetensors as belt-and-suspenders to minimize variables. Putting it back now that the next attempt has stabilized — adds it without risk.

This is the truth-test: NVIDIA's official docker + NVIDIA's verbatim recipe + clean memory. If this OOMs at graph capture, NVIDIA's recipe is genuinely broken on Spark (validating steveheh's complaint) → eugreugr's patched build is next.
