JAX-powered Cosmological Particle-Mesh N-body Solver
This project is currently in an early design phase. All inputs are welcome on the design document
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
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
- 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.
