cuda-bench 0.2.0

CUDA Kernel Benchmarking Package

CUDA Kernel Benchmarking Package

This package provides a Python API to the CUDA Kernel Benchmarking Library NVBench.

Installation

Install from PyPi

pip install cuda-bench[cu13]  # For CUDA 13.x
pip install cuda-bench[cu12]  # For CUDA 12.x

Building from source

Ensure recent version of CMake

Since nvbench requires a rather new version of CMake (>=3.30.4), either build CMake from sources, or create a conda environment with a recent version of CMake, using

conda create -n build_env --yes  cmake ninja
conda activate build_env

Ensure CUDA compiler

Since building NVBench library requires CUDA compiler, ensure that appropriate environment variables are set. For example, assuming CUDA toolkit is installed system-wide, and assuming Ampere GPU architecture:

export CUDACXX=/usr/local/cuda/bin/nvcc
export CUDAARCHS=86

Build Python project

Now switch to python folder, configure and install NVBench library, and install the package in editable mode:

cd nvbench/python
pip install -e .

Verify that package works

python test/run_1.py
