DPNP C++ backend documentation

Build from source:

Ensure you have the following prerequisite packages installed:

• cython
• cmake >=3.21
• dpcpp_linux-64 or dpcpp_win-64 (depending on your OS)
• dpctl
• mkl-devel-dpcpp
• onedpl-devel
• ninja
• numpy >=1.19,<1.25a0
• python
• scikit-build
• setuptools
• sysroot_linux-64 >=2.28 (only on Linux OS)
• tbb-devel

After these steps, dpnp can be built in debug mode as follows:

git clone https://github.com/IntelPython/dpnp
cd dpnp
python scripts/build_locally.py

Install Wheel Package via pip

Install DPNP

python -m pip install --index-url https://pypi.anaconda.org/intel/simple dpnp

Set path to Performance Libraries in case of using venv or system Python:

export LD_LIBRARY_PATH=<path_to_your_env>/lib

It is also required to set following environment variables:

export OCL_ICD_FILENAMES_RESET=1
export OCL_ICD_FILENAMES=libintelocl.so

Run test

pytest
# or
pytest tests/test_matmul.py -s -v
# or
python -m unittest tests/test_mixins.py

Run numpy external test

. ./0.env.sh
python -m tests.third_party.numpy_ext
# or
python -m tests.third_party.numpy_ext core/tests/test_umath.py
# or
python -m tests.third_party.numpy_ext core/tests/test_umath.py::TestHypot::test_simple

Building documentation:

Prerequisites:
$ conda install sphinx sphinx_rtd_theme
Building:
1. Install dpnp into your python environment
2. $ cd doc && make html
3. The documentation will be in doc/_build/html

Packaging:

. ./0.env.sh
conda-build conda-recipe/

Run benchmark:

cd benchmarks/

asv run --python=python --bench <filename without .py>
# example:
asv run --python=python --bench bench_elementwise

# or

asv run --python=python --bench <class>.<bench>
# example:
asv run --python=python --bench Elementwise.time_square

# add --quick option to run every case once but looks like first execution has additional overheads and takes a lot of time (need to be investigated)
