gko::ext

Optional integrations with external libraries. cuDSS is built when CMake finds it; the Kokkos and config-reader headers are always installed and need their dependency only in your application.

For the user-facing walk-through of each extension, see Extensions.

Available extensions

• Cudss: wraps NVIDIA’s cuDSS sparse direct solver as a Ginkgo LinOp. Lives in gko::ext::cuda::solver and requires a CUDA build with cuDSS available.

• Config file readers: gko::ext::config::parse_json, parse_json_file and parse_json_string (nlohmann_json), and parse_yaml and parse_yaml_file (yaml-cpp), turn a configuration file into the gko::config::pnode that gko::config::parse consumes.

• Kokkos interop: helpers for round-tripping Ginkgo’s array, Dense, and executor types through Kokkos views and execution spaces. Lives in gko::ext::kokkos; requires Kokkos in your application’s build.
