GERN: Lightweight Fusion for GPUs

🚧 Under Construction! 🚧

To build gern, install vcpkg and make sure VCPKG_ROOT is set in your environment. Then run:

$ cmake -DGern_CUDA_ARCH=<89,90..,etc> --preset dev
$ cmake --build build/dev

If -DGern_CUDA_ARCH is not set, none of the GPU kernels will be run during tests.

To run tests:

$ ctest --test-dir build/dev

Or to run a single test:

$ ctest --test-dir build/dev -R ExprNode.Literal

Testing Code Coverage

To test with code coverage, build with preset coverage:

$ cmake -DGern_CUDA_ARCH=<89,90..,etc> --preset coverage 
$ cmake --build build/coverage
$ ctest --test-dir build/coverage

Then, generate an html for the code coverage results from build/coverage:

$ gcovr -r  ~/gern/src/ CMakeFiles/Gern_Gern.dir/src/ --exclude-unreachable-branches --html-details -o <location>

See the CTest documentation for more detail.
