45  Build, Test, and CI

Use a debug build with unit tests for local development:

cmake -S . -B build_serial \
  -DBUILD_TYPE=Debug \
  -DPLATFORMS=SERIAL \
  -DOPALX_ENABLE_UNIT_TESTS=ON
cmake --build build_serial -j 8
ctest --test-dir build_serial --output-on-failure

Repeat relevant tests with OPENMP and the target accelerator backend. A test that passes only on the serial backend is not sufficient for a performance-portable change.

Pull-request CI includes serial, OpenMP, CUDA, and HIP compilation, with SYCL coverage where the runner supports it. Compile workflows run on labeled, non-draft pull requests to master; use the compile-ci label when the change is ready for those checks. Fast regression cases are executed with the serial artifact and compared to maintained metrics.
