Contact owners and managers

1–20 of 20

Welcome to the official Discussion group for CARLsim, an efficient, easy-to-use, GPU-accelerated library for simulating large-scale spiking neural network (SNN) models with a high degree of biological detail.

Download CARLsim 3.1: https://github.com/UCI-CARL/CARLsim3

The goal of CARLsim 4 is to provide multi-GPU support: https://github.com/UCI-CARL/CARLsim4
