The specification for SYCL 1.2.1, which is based on OpenCL 1.2, has been finalized and released on the Khronos website. The describe it as a major update over the previous standard, SYCL 1.2, and it is. Since May 2015, when SYCL 1.2 was finalized, The Khronos Group added features from C++11, C++14, and C++17, including the ISO C++17 Parallel Standard Template Library (STL).


In other words, you can create C++17 Parallel STL applications with SYCL 1.2.1, single-source, that are able to offload to OpenCL 1.2 devices.

Beyond that, the specification changes also help machine learning. The Khronos Group mentions that Google’s TensorFlow supports SYCL, bringing the framework to OpenCL devices. They want to continue updating the specification in this area, along with Safety Critical applications, such as automotive. They also want to keep updating the standard with ISO C++ features. In other words? SYCL is being adopted, and they intend ongoing support to match.

GDC 14: SYCL 1.2 Provisional Spec Released by Khronos

To gather community feedback, the provisional specification for SYCL 1.2 has been released by The Khronos Group. SYCL extends itself upon OpenCL with the C++11 standard. This technology is built on another Khronos platform, SPIR, which allows the OpenCL C programming language to be mapped onto LLVM, with its hundreds of compatible languages (and Khronos is careful to note that they intend for anyone to make their own compatible alternative langauge).


In short, SPIR allows many languages which can compile into LLVM to take advantage of OpenCL. SYCL is the specification for creating C++11 libraries and compilers through SPIR.

As stated earlier, Khronos wants anyone to make their own compatible language:

While SYCL is one possible solution for developers, the OpenCL group encourages innovation in programming models for heterogeneous systems, either by building on top of the SPIR™ low-level intermediate representation, leveraging C++ programming techniques through SYCL, using the open source CLU libraries for prototyping, or by developing their own techniques.

SYCL 1.2 supports OpenCL 1.2 and they intend to develop it alongside OpenCL. Future releases are expected to support the latest OpenCL 2.0 specification and keep up with future developments.

The SYCL 1.2 provisional spec is available at the Khronos website.
