Welcome to the Arbor Online Playground!

This is an Emscripten + Pyodide port of the Arbor Neural Simulator. This website is meant to be a simple showcase of neural modelling in Arbor. If you want to do serious work with it, we recommend installing arbor-gui for a graphical interface to arbor or the library itself via pip or building from source. While arbor is a stable robust simulator designed to run large scale simulation on thousands of CPU/GPU nodes, this port comes with some limitations. Notable, only single CPU simulations are supported. When requesting unavailable hardware resources or loading non existing morphology files, pyodide will internally crash which can only be resolved by refreshing the webpage. Loading of NeuroML morphologies is disabled because of libxml2 porting problems. Long running simulations will freeze the user interface. Please report any issues on GitHub.
