nvprobe 0.6.1

NVIDIA GPU benchmark suite for CUDA workload automation, reporting, and comparison

nvProbe

NVIDIA GPU & CUDA Benchmark Suite
Automate CUDA workloads • HPL & HPCG • MLPerf inference • Custom kernels • Interactive reports

pip install nvprobe && nvprobe setup && nvprobe run --local

---

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

• 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 — Plotly charts with GPU / transfer / precision dropdowns
• 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 compare --a results/run1 --b results/run2	Compare two runs
nvprobe run --config configs/cluster.yaml	Run with custom YAML config
nvprobe slurm submit --config configs/cluster.yaml	Submit Slurm job
nvprobe slurm status	Check Slurm job status
nvprobe setup --cuda 13	Setup with specific CUDA version

Charts

Plotly charts with interactive controls:

• Bandwidth — filter by GPU and transfer type (H2D / D2H / D2D)
• MatMul / Attention — filter by GPU and precision (fp32 / fp16)
• 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 — mlcr discovers cuDNN via system CUDA paths. If installed via pip 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)
