 ### Ginkgo
 
 preCICE optionally uses [Ginkgo](https://ginkgo-project.github.io/) for GPU- and OpenMP-accelerated [global radial-basis function mappings](configuration-mapping.html#execution-backends). To enable the feature in preCICE, use the CMake option `-DPRECICE_FEATURE_GINKGO_MAPPING=ON`. Using this feature in preCICE requires additionally [Kokkos](https://kokkos.org/).
