nvprobe 0.5.31

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

nvProbe: NVIDIA GPU & CUDA Benchmark Suite

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

nvProbe runs standardized benchmarks across your GPU fleet, captures environment details, stores results in SQLite, and generates self-contained HTML reports — helping HPC engineers and ML teams make data-driven hardware purchasing decisions.

Features

• Benchmark modules: Bandwidth, custom CUDA kernels (matmul, conv2d, attention), HPL, HPCG, MLPerf
• Slurm integration: Generate and submit sbatch scripts, run across multiple nodes/GPUs
• Environment fingerprinting: Driver version, CUDA version, GPU model, memory, PCI bus ID — captured automatically
• SQLite storage: All results persisted with full query capability
• CSV/JSON export: Raw data for programmatic access
• HTML reports: Self-contained reports with matplotlib charts, sidebar navigation, and comparison views
• YAML configs: Define test matrices (GPU models, precisions, batch sizes) declaratively
• Reproducible: Same config + same hardware = same results

Quick Start

pip install nvprobe
nvprobe setup                      # install cupy + HPL/HPCG + generate configs
nvprobe run --config nvprobe/configs/local.yaml --local

Or install from source

git clone https://github.com/SergioZ3R0/nvprobe.git
cd nvprobe
pip install -e .
nvprobe setup                      # installs nvprobe + self-contained CuPy
nvprobe run --config nvprobe/configs/local.yaml --local

Detect GPU environment

nvprobe env

Run benchmarks (dry run)

nvprobe run --config configs/default.yaml --dry-run

Run benchmarks

nvprobe run --config configs/default.yaml

Generate report

nvprobe report

Compare two runs

nvprobe compare --a results/run1 --b results/run2

Configuration

Edit configs/default.yaml to define your test matrix:

slurm:
  enabled: true
  partition: gpu
  gpus_per_node: 8

precisions:
  - fp32
  - fp16
  - int8

benchmarks:
  - name: bandwidth
    enabled: true
    params:
      sizes_mb: [1, 4, 16, 64, 256, 1024]
  - name: custom
