The dpctl is a foundational package facilitating use of SYCL to extend Python's reach to heterogeneous systems.

The dpctl provides Python API to SYCL runtime permitting user to inspect the heterogeneous platform, select amongst available devices, query properties of created devices, and construct queues to specify execution placement of offloaded computation.

Additionally, dpctl.tensor submodule allows to create ND-arrays on devices and manipulate them using dpctl.tensor library of array computation operations specified in Python Array API standard.

Examples of this functionality are located in the python folder.

The dpctl integrates with Cython, a native extension generator, to facilitate building SYCL-powered Python extensions.

Examples of Python extensions written using Cython are located in the cython folder.

Since SYCL is based on C++, pybind11 is a natural tool of choice to author SYCL-powered Python extensions. The dpctl provides dpctl4pybind11.hpp integration header to provide natural mapping between SYCL C++ classes and dpctl Python types.

Examples of Python extensions created with pybind11 are located in the pybind11 folder.

The dpctl implements DPCTLSyclInterface C library and C-API to work with Python objects and types implemented in dpctl. Use integration headers dpctl_sycl_interface.h and dpctl_capi.h to access this functionality.

Examples of Python extensions created using C are located in c folder.
