Optimized operators for HyTeG

This repository contains optimized elementwise operators for HyTeG. The code under operators is generated using the HOG. Each kernel has a platform independent and, where applicable, an AVX-vectorized version. The desired variant is configured in CMake.

All operators are described declaratively in operators-<operator-group>.toml. They are roughly split into groups for a better overview and faster integration tests.

How to generate operators

cd generate

python -m venv .venv
source .venv/bin/activate
python -m pip install -r requirements.txt

python generate.py -o ../operators ../operators-<operator-group>.toml

# To generate all operators you have to run the script repeatedly, each time with a different toml file.
