tbb4u

Wheels for oneTBB (oneAPI Thread Building Blocks), published to PyPI as tbb4u.

Each wheel bundles the oneTBB shared libraries (tbb, tbbmalloc) built unmodified from an upstream release tag. The wheel version matches the packaged oneTBB release (e.g. 2023.1.0). The tbbmalloc_proxy interposition shim is not included.

How it works

CMakeLists.txt here is only a thin shim: it add_subdirectory()s a checkout of uxlfoundation/oneTBB (pointed at by the ONE_TBB_SOURCE_DIR variable or environment variable) and installs the built libraries into the tbb4u package directory. All build logic lives upstream.
.github/workflows/build.yml is manually triggered and builds a matrix of OS (windows/linux/macos) x architecture (intel/arm) x oneTBB tag with cibuildwheel, then uploads everything to PyPI via trusted publishing.
To package a new oneTBB release, add its tag to the matrix in the workflow (both build_wheels and build_sdist).

Usage

import tbb4u

tbb4u.__version__   # e.g. "2023.1.0"
lib = tbb4u.load()  # ctypes handle to the bundled libtbb

License

The packaging shim is Apache-2.0. The bundled oneTBB sources are Apache-2.0 (with LLVM exceptions); their license texts ship inside each wheel under tbb4u/licenses/.
