Arbor¶
Welcome to the documentation for Arbor, the multi-compartment neural network simulation library.
You can find out how to get Arbor; get started quickly with our tutorials; or continue reading to learn more about Arbor.
What is Arbor?¶
Arbor is a high-performance library for computational neuroscience simulations with multi-compartment, morphologically-detailed cells, from single cell models to very large networks. Arbor is written from the ground up with many-cpu and gpu architectures in mind, to help neuroscientists effectively use contemporary and future HPC systems to meet their simulation needs.
Arbor supports NVIDIA and AMD GPUs as well as explicit vectorization on CPUs from Intel (AVX, AVX2 and AVX512) and ARM (Neon and SVE). When coupled with low memory overheads, this makes Arbor an order of magnitude faster than the most widely-used comparable simulation software.
Arbor is open source and openly developed, and we use development practices such as unit testing, continuous integration, and validation.
Documentation organisation¶
Features is an index of Arbor’s major neuroscientific features and a collection of best practices and experiences collected from the Arbor modelling community, meant to spread information on how to solve common modelling questions in Arbor.
Tutorials contains a few ready-made examples you can use to quickly get started using Arbor. In the tutorial descriptions we link to the relevant Arbor concepts.
Concepts overview describes the design and concepts used in Arbor. The breakdown of concepts is mirrored (as much as possible) in the Python and C++, so you can easily switch between languages and concepts.
The API section details our Python and C++ API. The Developers Guide describes Arbor code that is not user-facing; convenience classes, architecture abstractions, and other information that is relevant to understanding the inner workings of Arbor and the mathematical foundations underpinning the engine.
Contributions to Arbor are very welcome! Under Contributing you’ll find the conventions and procedures for all kinds of contributions.
