CULiNGAM is a high-performance library that accelerates Linear Non-Gaussian Acyclic Model (LiNGAM) analysis on GPUs. It leverages the computing power of NVIDIA GPUs to provide fast and efficient computations for LiNGAM applications, making it ideal for large-scale data analysis in fields such as bioinformatics, economics, and machine learning. CULiNGAM can be more more than 32x faster than CPU implementations: https://arxiv.org/abs/2403.03772.
To install CULiNGAM, you need a system with NVIDIA CUDA installed and a compatible GPU. This library is tested with CUDA 12.2 and designed for GPUs with the architecture sm_86, although it may work with other versions and architectures with appropriate adjustments.
- NVIDIA GPU with CUDA Compute Capability 6.0 or higher
- CUDA Toolkit 12.2 or compatible version
- Python 3.6 or newer
- Numpy
- A C++17 compatible compiler
CULiNGAM is available on PyPI and can be easily installed with pip:
pip install culingam- Clone the repository to your local machine:
git clone https://github.com/Viktour19/culingam- Ensure that CUDA_HOME environment variable is set to your CUDA Toolkit installation path. If not, you can set it as follows (example for default CUDA installation path):
export CUDA_HOME=/usr/local/cuda-12.2- Optionally, set the GPU_ARCH environment variable to match your GPU architecture if it differs from the default sm_86:
export GPU_ARCH=sm_xx # Replace xx with your GPU's compute capability- Install the library using pip:
pip install .After installation, you can use CULiNGAM in your Python projects to accelerate LiNGAM analysis. Here's a simple example to get started:
