A Brian2 extension to simulate spiking neural networks on GPUs

Brian2CUDA

Brian2CUDA is an extension of the spiking neural network simulator Brian2, written in Python. It generates C++/CUDA code to run simulations on NVIDIA GPUs.

For support, please use the Brian forum. If you think you found a bug in Brian2CUDA, please report it at the GitHub issue tracker.

For installation and usage instructions, check out the Brian2CUDA documentation. For information on general Brian2 usage, check out the Brian2 documentation.

Quick start

Installation

You can install Brian2CUDA via pip:

python -m pip install brian2cuda

This will install a compatible version of Brian2 as dependency. For installation requirements and GPU configuration, check out the Brian2CUDA documentation.

Usage

Use your Brian2 code (see Brian2 documentation) and modify the imports to:

# Standard Brian2 import
from brian2 import *

# Enable GPU usage via Brian2CUDA
import brian2cuda
set_device("cuda_standalone")

See Brian2's standalone code generation for more options for the set_device call.
