JAX-powered Cosmological Particle-Mesh N-body Solver
|
|
|
|
**This project is currently in an early design phased. All inputs are welcome on the [design document](https://github.com/DifferentiableUniverseInitiative/JaxPM/blob/main/design.md)**
|
|
|
|
## Goals
|
|
|
|
Provide a modern infrastructure to support differentiable PM N-body simulations using JAX:
|
|
- Keep implementation simple and readable, in pure NumPy API
|
|
- Transparent distribution using builtin `xmap`
|
|
- Any order forward and backward automatic differentiation
|
|
- Support automated batching using `vmap`
|
|
- Compatibility with external optimizer libraries like `optax`
|
|
|
|
## 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.
