Kernel functions for your geophysical models

About
Choclo is a Python library that hosts optimized kernel functions for running geophysical forward and inverse models, intended to be used by other libraries as the underlying layer of their computation. "Choclo" is a term used in some countries of South America to refer to corn, originated from the quechua word chuqllu.
Project goals
- Provide optimized kernel functions for gravity and magnetic forward and inverse models that can be easily harnessed by different geophysical libraries.
- Generate a pure-Python library that could be easily distributed and installed on any operating system.
- Rely on Numba for just-in-time compilations and optional parallelization.
- Keep the dependencies to the bare minimum to encourage other libraries to depend on Choclo.
Project status
Choclo is ready for use but still changing. This means that we sometimes break backwards compatibility as we try to improve the software based on user experience, new ideas, better design decisions, etc. Please keep that in mind before you update Choclo to a newer version.
We welcome feedback and ideas! This is a great time to bring new ideas on how we can improve the project. Join the conversation or submit issues on GitHub.
