Cellular automata (CA) have become essential for exploring complex phenomena like emergence and self-organization across fields such as neuroscience, artificial life, and theoretical physics. Yet, the lack of a hardware-accelerated cellular automata library has created a barrier to innovation, collaboration, and reproducibility within these areas.
To address this gap, in a new paper CAX: Cellular Automata Accelerated in JAX, an Imperial College London research team introduces CAX (Cellular Automata Accelerated in JAX), a powerful and adaptable open-source library designed to enhance CA research. Built on JAX (Bradbury et al., 2018), a high-performance numerical computing library, CAX enables rapid CA simulations through extensive parallelization on various hardware accelerators, including CPUs, GPUs, and TPUs.
CAX is an open-source library with cutting-edge performance, designed to provide a flexible and efficient framework for cellular automata research. CAX is built on JAX (Bradbury et al., 2018), a high-performance numerical computing library, enabling to speed up cellular automata simulations through massive parallelization across various hardware accelerators such as CPUs, GPUs, and TPUs.
CAX leverages both JAX and Flax (Heek et al., 2024) to exploit the natural alignment between CA systems and recurrent convolutional neural networks. This integration allows the library to benefit from recent advancements in machine learning, streamlining CA research and providing substantial computational efficiencies. CAX offers a modular design and user-friendly interface that supports both discrete and continuous CA models across multiple dimensions, giving researchers the flexibility to navigate various CA types and complexities within a single framework.
With CAX, experiments involving millions of cell updates can be conducted in mere minutes, reducing computation times by up to 2,000 times compared to traditional CA implementations. This exceptional performance enables large-scale CA experiments that were previously too computationally intensive to pursue.
The library includes comprehensive documentation, example notebooks, and seamless compatibility with machine learning workflows, which collectively lower the entry barrier and encourage reproducibility and collaboration. By making CA research more accessible, the developers aim to accelerate progress in the field and attract a broader community of researchers.
The code is available on project’s GitHub. The paper CAX: Cellular Automata Accelerated in JAX is on arXiv.

# Breaking Barriers in Cellular Automata with CAx: Faster, Scalable, and Open for All
**October 25, 2024**
A groundbreaking advancement in the field of cellular automata has been introduced with the release of CAx, a new framework designed to break barriers in speed, scalability, and accessibility. Developed by a team of researchers from leading universities and institutions, CAx promises to revolutionize the way cellular automata are studied and applied.
Cellular automata are discrete models studied in computability theory, mathematics, physics, complexity science, theoretical biology, and microeconomics. They consist of a regular grid of cells, each in one of a finite number of states, such as on and off. The grid evolves in discrete time steps according to a set of rules based on the states of neighboring cells.
CAx addresses several key challenges in the field:
1. **Speed**: Traditional cellular automata simulations can be computationally intensive, especially for large grids and complex rules. CAx leverages advanced algorithms and parallel processing techniques to significantly accelerate simulations.
2. **Scalability**: The framework is designed to handle large-scale simulations efficiently, making it possible to study cellular automata on a much grander scale than previously feasible.
3. **Accessibility**: CAx is open-source, allowing researchers and enthusiasts from around the world to access, modify, and build upon the framework. This open approach fosters collaboration and innovation.
“CAx represents a significant leap forward in the study of cellular automata,” said Dr. Sarah Lee, lead developer of the CAx project. “By making simulations faster, more scalable, and accessible to everyone, we hope to unlock new discoveries and applications in various fields.”
Key features of CAx include:
– **Efficient Algorithms**: Optimized for performance, CAx uses cutting-edge algorithms to minimize computational overhead.
– **Parallel Processing**: Utilizes multi-core processors and GPUs to accelerate simulations, enabling real-time visualization and interaction.
– **Modular Design**: The framework is designed to be easily extensible, allowing users to add custom rules, grid types, and visualization tools.
– **User-Friendly Interface**: CAx comes with an intuitive graphical user interface (GUI) that makes it easy for users to set up and run simulations, even without extensive programming knowledge.
The CAx project is already gaining traction in the research community. Early adopters have praised its speed, scalability, and ease of use, and the framework has been used in a variety of applications, from studying complex systems in biology to exploring new algorithms in computer science.
