Unified Runtime

Contents

This repo 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)

Weekly Tags

Each Friday at 23:00 UTC time a prerelease tag is created which takes the form weekly-YYYY-MM-DD. These tags should be used by downstream projects which intend to track development closely but maintain a fixed point in history to avoid pulling potentially breaking changes from the main branch.

Source Code Generation

Code is generated using included Python scripts.

Documentation

Documentation is generated from source code using Sphinx.

Third-Party Tools

Tools can be acquired via instructions in third_party.

Building

Requirements:

• C++ compiler with C++17 support
• cmake >= 3.14.0
• clang-format-15.0 (can be installed with python -m pip install clang-format==15.0.7)

Project is defined using CMake.

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:

Name	Description	Values	Default
UR_BUILD_TESTS	Build the tests	ON/OFF	ON
UR_FORMAT_CPP_STYLE	Format code style	ON/OFF	OFF
UR_DEVELOPER_MODE	Treat warnings as errors and enables additional checks	ON/OFF	OFF
UR_USE_ASAN	Enable AddressSanitizer	ON/OFF	OFF
UR_USE_UBSAN	Enable UndefinedBehavior Sanitizer	ON/OFF	OFF
UR_USE_MSAN	Enable MemorySanitizer (clang only)	ON/OFF	OFF
UR_ENABLE_TRACING	Enable XPTI-based tracing layer	ON/OFF	OFF

General:

To run automated code formatting build with option UR_FORMAT_CPP_STYLE and then run a custom cppformat target:

$ make cppformat

If you've made modifications to the specification, you can also run a custom generate-code or generate target prior to building. This call will generate the source code:

$ make generate-code

This call will generate the source code and run automated code formatting:

$ make generate

Note: generate target requires UR_FORMAT_CPP_STYLE to bet set.

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.
