Features
| Bandwidth | MatMul / Attention | Conv2D |
|---|---|---|
| H2D / D2H / D2D across buffer sizes | fp32, fp16, int8 custom CUDA kernels | 2D convolution benchmarks |
| HPL (FP64 Linpack) | HPCG | MLPerf Inference |
| Datacenter GPUs: A100, H100, B200, L40S… | Conjugate Gradients | ONNX Runtime via cmx4mlperf |
| Memtest | Burn | |
| VRAM integrity: solid, checkerboard, random, walking-1 patterns | Sustained clock stability, thermal/power throttling detection |
- Bundled CUDA runtime — CuPy
[ctk]via pip, no system toolkit required - Auto-downloaded HPC tools — NVIDIA HPC Benchmarks cached in
~/.nvprobe/tools/ - Interactive HTML reports — Chart.js charts with GPU / transfer / precision dropdowns and oscilloscope-style glow
- GPU diagnostics — max clocks, power limits, ECC state, PCIe link speed, NVLink active links captured per run
- Memory integrity — memtest with solid, checkerboard, random, and walking-1 patterns to detect VRAM faults
- Thermal soak — sustained burn test with time-series clock/temp/power tracking and throttling detection
- A/B comparison — compare two result sets side-by-side
- Slurm integration — generate, submit, monitor, collect from HPC clusters
- SQLite storage — all results persisted; CSV / JSON export
Quick Start
| Step | Command | What it does |
|---|---|---|
| 1 | pip install nvprobe |
Install the package |
| 2 | nvprobe setup |
Install CuPy, download HPL/HPCG, generate configs |
| 3 | nvprobe env |
Verify GPU detection, driver, CUDA version |
| 4 | nvprobe run --local |
Run all benchmarks locally |
| 5 | nvprobe report --open |
Generate & open interactive HTML report |
Or from source:
git clone https://github.com/SergioZ3R0/nvprobe.git && cd nvprobe
pip install -e . && nvprobe setup && nvprobe run --local
More commands
| Command | Description |
|---|---|

nvprobe slurm status |
Check Slurm job status |
nvprobe setup --cuda 13 |
Setup with specific CUDA version |
Charts
Chart.js canvas-based charts with interactive controls:
- Bandwidth — filter by GPU and transfer type (H2D / D2H / D2D)
- MatMul / Attention — filter by GPU and precision (fp32 / fp16)
- Burn — time-series line chart of SM/MEM clocks and temperature over sustained load
- Memtest — bar chart of detected VRAM errors per test pattern
- Range slider — zoom into any x-axis region
- Moving average — smoother trend lines for dense data

Notes
- HPL / HPCG — NVIDIA HPC Benchmarks binaries are validated for datacenter GPUs (A100, H100, B200, L40S…). They may crash (SIGSEGV) on RTX series. Bandwidth and custom kernels work on any CUDA GPU.
- MLPerf cuDNN —
mlcrdiscovers cuDNN via system CUDA paths. If installed viapip install nvidia-cudnn-cuXX, pre-register with:mlcr get,cudnn,nvidia --input=$(python3 -c 'import nvidia.cudnn; print(nvidia.cudnn.__path__[0]'))
Requirements
Python 3.10+ • NVIDIA GPU with CUDA drivers • nvidia-smi in PATH • Slurm (optional)
