CUDA target for Numba

Numba CUDA Target

An out-of-tree CUDA target for Numba.

This contains an entire copy of Numba's CUDA target (the numba.cuda module), and a mechanism to ensure the code from this module (numba_cuda.numba.cuda) is used as the numba.cuda module instead of the code from the numba package.

This is presently in an early state and is published for testing and feedback.

Building / testing

Install as an editable install:

pip install -e .

Running tests:

python -m numba.runtests numba.cuda.tests

This should discover thenumba.cuda module from the numba_cuda package. You can check where numba.cuda files are being located by running

python -c "from numba import cuda; print(cuda.__file__)"

which will show a path like:

<path to numba-cuda repo>/numba_cuda/numba/cuda/__init__.py

Branching strategy

Presently the main branch is being used to target the exact behavior of the built-in CUDA target. New feature development and bug fixes should be applied to develop. Once the main branch is widely tested and confirmed to work well as a drop-in replacement for the built-in numba.cuda, the develop branch will be merged in and new feature development will proceed on main.

Current PR targets

• PRs related to replacing the built-in CUDA target's features should target main.
• PRs adding new features and bug fixes should target develop.

Future PR targets

• In future, all PRs should target the main branch.
