Today, The Khronos Group, an open consortium of industry-leading companies creating graphics and compute interoperability standards, announces the ratification and public release of the SYCL 2020 Provisional Specification. SYCL is a standard C++ based heterogeneous parallel programming framework for accelerating High Performance Computing (HPC), machine learning, embedded computing, and compute-intensive desktop applications on a wide range of processor architectures, including CPUs, GPUs, FPGAs, and AI processors.The SYCL 2020 Provisional Specification is publicly available today to enable feedback from developers and implementers before the eventual specification finalization and release of the SYCL 2020 Adopters Program, which will enable implementers to be officially conformant—tentatively expected by the end of the year.

A royalty-free open standard, SYCL 2020 enables significant programmer productivity through an expressive domain-specific language, compact code, and simplified common patterns, such as Class Template Argument Deduction and Deduction Guides, all while preserving significant backwards compatibility with previous versions. SYCL 2020 is based on C++17 and includes new programming abstractions, such as unified shared memory, reductions, group algorithms, and sub-groups to enable high-performance applications across diverse hardware architectures.
