JAX-powered Cosmological Particle-Mesh N-body Solver
|
||
|
||
## Goals
|
||
|
||
Provide a modern infrastructure to support differentiable PM N-body simulations using JAX:
|
||
- Keep implementation simple and readable, in pure NumPy API
|
||
- Any order forward and backward automatic differentiation
|
||
- Support automated batching using `vmap`
|
||
- Compatibility with external optimizer libraries like `optax`
|
||
- Now fully distributable on **multi-GPU and multi-node** systems using [jaxDecomp](https://github.com/DifferentiableUniverseInitiative/jaxDecomp) working with the latex `JAX v0.4.35`
|
||
|
||
|
||
## Open development and use
|
||
|
||
Current expectations are:
|
||
- This project is and will remain open source, and usable without any restrictions for any purposes
|
||
- Will be a simple publication on [The Journal of Open Source Software](https://joss.theoj.org/)
|
||
- Everyone is welcome to contribute, and can join the JOSS publication (until it is submitted to the journal).
|
||
- Anyone (including main contributors) can use this code as a framework to build and publish their own applications, with no expectation that they *need* to extend authorship to all jaxpm developers.
|
||
|
||
## Getting Started
|
||
|
||
To dive into JaxPM’s capabilities, please explore the **notebook section** for detailed tutorials and examples on various setups, from single-device simulations to multi-host configurations. You can find the notebooks' [README here](notebooks/README.md) for a structured guide through each tutorial.
