superneuromat 3.2.0

A fast and scalable matrix-based simulator for Spiking Neural Networks (SNNs).

SuperNeuroMAT

The Super Speedy Spike Simulator.

SuperNeuroMAT is a Python package for simulating and analyzing spiking neural networks.

Documentation available: https://ORNL.github.io/superneuromat/

Unlike its sister package, SuperNeuroABM, SuperNeuroMAT uses a matrix-based representation of the network, which allows for more efficient simulation and GPU acceleration.

SuperNeuroMAT focuses on super-fast computation of Leaky Integrate and Fire (LIF) spiking neuron models with STDP.

It provides:

1. Support for leaky integrate and fire neuron model with the following parameters:

• neuron threshold
• neuron leak
• neuron refractory period

2. Support for Spiking-Time-Dependent Plasticity (STDP) on synapses with:

• weight
• delay
• per-synapse disabling of learning

3. Support for all-to-all connections as well as self connections
4. A turing-complete model of neuromorphic computing
5. Optional GPU acceleration or Optional Sparse computation

• Note that long delays may impact performance. Consider using an agent-based simulator such as SuperNeuroABM for longer delays.

Installation

1. Install using pip install superneuromat
2. Update/upgrade using pip install superneuromat --upgrade

The installation guide covers virtual environments, faster installation with uv, installing support for CUDA GPU acceleration, and more.

Usage

Import the spiking neural network class:

from superneuromat import SNN

See the tutorial for more.

Additionally, the migration guide may be of use to those coming from older versions of SuperNeuroMAT.
