The GridTools Framework is a set of libraries and utilities for the weather and climate domain. GridTools is an effort led by CSCS at ETH Zurich. Community contributions that are aligned with the goals of the GridTools framework are welcome.
The main projects in the GridTools Framework are
GridTools C++ (sometimes just "GridTools"). Historically, the core of the GridTools framework, is a set of C++ utilities of different kind, from generic meta programming utilities to a domain-specific Stencil DSL. The GridTools Stencil DSL is used to implement the COSMO dynamical core in the official release at http://cosmo-model.org/.
Active development is currently mainly in supporting functionality for backends used by GT4Py (fn
library).
GT4Py is a library that brings the idea of GridTools C++ to Python. Its central piece is a Stencil DSL that is translated to GridTools C++ and other backends for efficient execution on a variety of architectures.
