Contents of the project

This project contains the following:

• API specification in YaML
• API programming guide in RST
• Loader and a null adapter implementation (partially generated)
• Example applications
• API C/C++ header files (generated)
• API Python module (generated)
• Sample C++ wrapper (generated)
• Sample C/C++ import library (generated)

Integration

The recommended way to integrate this project into another is via CMake's FetchContent, for example:

include(FetchContent)

FetchContent_Declare(
    unified-runtime
    GIT_REPOSITORY https://github.com/oneapi-src/unified-runtime.git
    GIT_TAG main  # This will pull the latest changes from the main branch.
)
FetchContent_MakeAvailable(unified-runtime)

add_executable(example example.cpp)
target_link_libraries(example PUBLIC unified-runtime::headers)

Third-Party tools

The recommended method to install the third-party tools is using a Python virtual environment, for example:

$ python -m venv .venv
$ source .venv/bin/activate
$ pip install -r third_party/requirements.txt

Building

The requirements and instructions below are for building the project from source without any modifications. To make modifications to the specification, please see the Contribution Guide for more detailed instructions on the correct setup.

Requirements

Required packages:

• C++ compiler with C++17 support
• CMake >= 3.20.0
• Python v3.6.6 or later

Windows

Generating Visual Studio Project. EXE and binaries will be in build/bin/{build_config}

$ mkdir build
$ cd build
$ cmake {path_to_source_dir} -G "Visual Studio 15 2017 Win64"

Linux

Executable and binaries will be in build/bin

$ mkdir build
$ cd build
$ cmake {path_to_source_dir}
$ make

CMake standard options

List of options provided by CMake:

Additional make targets

To run tests, do the following:

To run automated code formatting, configure CMake with UR_FORMAT_CPP_STYLE option and then run a custom cppformat target:

If you've made modifications to the specification, you can also run a custom generate target prior to building. It will generate the source code and run automated code formatting:

This target has additional dependencies which are described in the Build Environment section of the Contribution Guide.

Contributions

For those who intend to make a contribution to the project please read our Contribution Guide for more information.

Adapter naming convention

To maintain consistency and clarity in naming adapter libraries, it is recommended to use the following naming convention:

• On Linux platforms, use libur_adapter_[name].so.
• On Windows platforms, use ur_adapter_[name].dll.

Source code generation

Code is generated using included Python scripts.

Documentation

Documentation is generated from source code using Sphinx - see scripts dir for details.
