# MBFS CUDA Runtime Bundle

Self-contained, **ABI-matched** CUDA execution stacks for running
[ONNX Runtime](https://onnxruntime.ai/) on Windows with the CUDA / TensorRT
execution providers. One folder per CUDA major version:

| Stack | Folder | CUDA | cuDNN | ONNX Runtime EP | When to use |
|---|---|---|---|---|---|
| **cu12** | [`cuda_v12/`](./cuda_v12) | 12.x | 9 | CUDA + TensorRT 10 | sm_75+ GPU on driver **R527+** (CUDA 12) |
| **cu11** | [`cuda_v11/`](./cuda_v11) | 11.x | 8 | CUDA + TensorRT 8.6 | Pascal/Volta (sm_60–sm_70), or any GPU on a driver capped at CUDA 11.x |

Pick the stack matching your GPU **and** driver: a newer GPU on an older driver
must still use `cu11` (loading `cu12` binaries fails with
`cudaErrorNoKernelImageForDevice`). The MBFS Sentinel build auto-detects this —
`scripts/build_windows.py` clamps the stack to the lower of the GPU and driver
ceilings (override with `--gpu-stack`).

**TensorRT engine-build libraries** live in a *companion* folder,
[`trt_v12/`](./trt_v12) (for the `cu12` stack). These are the TensorRT 10
runtime + parser (`nvinfer*`, `nvonnxparser`) and the per-SM **builder
resources** used when TensorRT compiles an engine. It is **not** a standalone
CUDA stack — pair it with `cuda_v12/` (whose `onnxruntime_providers_tensorrt.dll`
is only the small ONNX Runtime ↔ TensorRT bridge). Unlike the CUDA folders,
`trt_v12/` is fetched **selectively**: a build downloads only the one builder
resource matching the target GPU's compute capability (plus the always-included
PTX fallback), not the whole ~2.8 GiB set. See
**[Contents (`trt_v12/`)](#contents-trt_v12)**.

## Contents (`cuda_v12/`)

| File | Component | Approx. size |
|---|---|---|
| `onnxruntime.dll` | ONNX Runtime 1.23.2 (combined CUDA + DirectML + TensorRT + CPU build) | 15 MB |
| `onnxruntime_providers_cuda.dll` | ONNX Runtime CUDA execution provider | 361 MB |
| `onnxruntime_providers_tensorrt.dll` | ONNX Runtime TensorRT execution provider | <1 MB |
| `onnxruntime_providers_shared.dll` | ONNX Runtime shared provider interface | <1 MB |
| `cublas64_12.dll`, `cublasLt64_12.dll` | CUDA 12 cuBLAS | 96 / 451 MB |
| `cudart64_12.dll` | CUDA 12 runtime | <1 MB |
| `cufft64_11.dll` | CUDA 12 cuFFT | 279 MB |
| `curand64_10.dll`, `cusparse64_12.dll` | CUDA 12 cuRAND / cuSPARSE | 62 / 264 MB |
| `cudnn64_9.dll` + `cudnn_*64_9.dll` (7 files) | cuDNN 9 | ~1.4 GB |

**Total ≈ 2.3 GiB.**

## Contents (`cuda_v11/`)

| File | Component | Approx. size |
|---|---|---|
| `onnxruntime.dll` | ONNX Runtime (CUDA + TensorRT + CPU build) | 13 MB |
| `onnxruntime_providers_cuda.dll` | ONNX Runtime CUDA execution provider | 223 MB |
| `onnxruntime_providers_tensorrt.dll` | ONNX Runtime TensorRT execution provider | <1 MB |
| `onnxruntime_providers_shared.dll` | ONNX Runtime shared provider interface | <1 MB |
| `cublas64_11.dll`, `cublasLt64_11.dll` | CUDA 11 cuBLAS | 85 / 519 MB |
| `cudart64_110.dll` | CUDA 11 runtime | <1 MB |
| `cufft64_10.dll` | CUDA 11 cuFFT | 267 MB |
| `curand64_10.dll`, `cusparse64_11.dll` | CUDA 11 cuRAND / cuSPARSE | 62 / 265 MB |
| `cudnn64_8.dll` + `cudnn_{adv,cnn,ops}_{infer,train}64_8.dll` (6 files) | cuDNN 8 | ~1.0 GB |

**Total ≈ 2.4 GiB.** cuDNN 8 keeps inference and training libraries split
(`*_infer` / `*_train`), unlike cuDNN 9.

> All DLLs in a folder come from a single matched build — the ONNX Runtime
> provider DLLs are ABI-locked to that folder's `onnxruntime.dll`, so each set
> must be used together (never mix DLLs across folders or with another ONNX
> Runtime release, or the CUDA EP fails to load).

## Contents (`trt_v12/`)

TensorRT 10 for the `cu12` stack, split into **core** (always needed) and
**per-SM builder resources** (one per GPU architecture). A build pulls the core
plus **only** the resource matching the target GPU's compute capability, plus
the PTX fallback — typically ≈ 1.0–1.7 GiB instead of the full ≈ 2.8 GiB.

**Core — always downloaded:**

| File | Component | Approx. size |
|---|---|---|
| `nvinfer_10.dll` | TensorRT 10 core inference runtime + builder | 432 MB |
| `nvinfer_plugin_10.dll` | TensorRT 10 standard plugins | 53 MB |
| `nvonnxparser_10.dll` | ONNX → TensorRT network parser | 3 MB |
| `nvrtc64_120_0.dll` | NVRTC runtime compiler (CUDA 12) | 44 MB |

**Per-SM builder resources — download only the one matching your GPU:**

| File | Architecture | Example GPUs | Approx. size |
|---|---|---|---|
| `nvinfer_builder_resource_ptx_10.dll` | **PTX JIT fallback — always included** | (any, forward-compat) | 488 MB |
| `nvinfer_builder_resource_sm75_10.dll` | Turing | T4, RTX 20xx | 157 MB |
| `nvinfer_builder_resource_sm80_10.dll` | Ampere | A100, A30 | 256 MB |
| `nvinfer_builder_resource_sm86_10.dll` | Ampere | A40, RTX 30xx | 241 MB |
| `nvinfer_builder_resource_sm89_10.dll` | Ada | L4, L40, RTX 40xx | 254 MB |
| `nvinfer_builder_resource_sm90_10.dll` | Hopper | H100, H200 | 661 MB |
| `nvinfer_builder_resource_sm120_10.dll` | Blackwell | B100/B200, RTX 50xx | 377 MB |

**Full set ≈ 2.8 GiB** (4 core + 7 resources). Example single-SM footprint —
Ampere A30 (sm80): core (532 MB) + PTX (488 MB) + `sm80` (256 MB) ≈ **1.2 GiB**.

> The builder resources are only needed when TensorRT **compiles** an engine
> (the first run for a given model/GPU). `nvinfer_10.dll` loads the matching
> `nvinfer_builder_resource_sm<cc>_10.dll` from the DLL search path at
> engine-build time; the MBFS Sentinel build stages them under
> `dist/lib/trt_v12/` and adds that directory to the process `PATH`. Once an
> engine cache (`.engine`/`.trt`) exists, the resource for that SM is no longer
> read.

## Requirements

- **OS:** Windows x64
- **NVIDIA driver:** `cu12` needs **R527+** (CUDA 12.x); `cu11` needs **R452+**
  (CUDA 11.x). The CUDA *Toolkit* does **not** need to be installed — these
  bundles ship the runtime.
- **GPU:** see the support notes below.

## GPU support

### `cu12`

`cuda_v12/onnxruntime_providers_cuda.dll` is compiled with cubins for the
following architectures (no PTX is embedded, so there is **no JIT
forward-compatibility** to newer archs):

| Compute capability | Architecture | Example GPUs | Native CUDA |
|---|---|---|---|
| 5.2 | Maxwell | GTX 9xx | ✅ |
| 6.0 | Pascal | Tesla P100 | ✅ |
| 7.0 | Volta | V100 | ✅ |
| 7.5 | Turing | T4, RTX 20xx | ✅ |
| 8.0 | Ampere | A100, A30 | ✅ |
| 8.6 | Ampere | A40, RTX 30xx | ✅ |
| 8.9 | Ada | L4, L40, RTX 40xx | ✅ |
| 9.0a | Hopper | H100, H200 | ✅ |
| 10.x / 12.x | **Blackwell** | B100/B200, RTX 50xx | ❌ not native |

For the **TensorRT** path the per-SM builder resources in `trt_v12/` cover
`sm75 / sm80 / sm86 / sm89 / sm90 / sm120`; older archs (sm_52/60/70) fall back
to the PTX builder resource (JIT). Pick the resource by compute capability:
`sm = major*10 + minor` (e.g. 8.0 → `sm80`, 12.0 → `sm120`).

### `cu11`

The `cu11` stack is the fallback for machines that predate CUDA 12: NVIDIA
**Pascal (sm_60) → Volta (sm_70)**, and any otherwise-cu12-capable GPU running
on a driver that only supports CUDA 11.x. Use it when `nvidia-smi` reports a
CUDA version below 12.0, or for Pascal/Volta silicon. For newer GPUs on a
current driver, prefer `cu12`.

On a GPU outside the supported range, or with a too-old driver, the host
application should fall back to DirectML (`DmlExecutionProvider`, requires
`DirectML.dll` — **not** included here) or CPU. These bundles cover the native
CUDA path only.

## Usage

The MBFS Sentinel build pulls the right stack automatically
(`build_windows.py --gpu-stack {cu12|cu11} --cuda-source hf`), including the
matching TensorRT builder resource (`--tensorrt-source hf`, default). To fetch a
stack manually:

```bash
# cu12 into ./dist/lib (lands at ./dist/lib/cuda_v12/)
hf download MBFSAITeam/cuda-runtime-bundle --repo-type dataset \
  --include "cuda_v12/*" --local-dir ./dist/lib

# cu11 into ./dist/lib (lands at ./dist/lib/cuda_v11/)
hf download MBFSAITeam/cuda-runtime-bundle --repo-type dataset \
  --include "cuda_v11/*" --local-dir ./dist/lib
```

For TensorRT, fetch the **core + PTX + only your GPU's SM** instead of the whole
folder (example for an Ampere A30, sm80):

```bash
hf download MBFSAITeam/cuda-runtime-bundle --repo-type dataset \
  --include "trt_v12/nvinfer_10.dll" \
  --include "trt_v12/nvinfer_plugin_10.dll" \
  --include "trt_v12/nvonnxparser_10.dll" \
  --include "trt_v12/nvrtc64_120_0.dll" \
  --include "trt_v12/nvinfer_builder_resource_ptx_10.dll" \
  --include "trt_v12/nvinfer_builder_resource_sm80_10.dll" \
  --local-dir ./dist/lib
```

For reproducible builds, pin a commit revision with `--revision <sha>` instead of
`main`.
