Today, the Khronos Group announced the ratification and public release of the SYCL™ 2020 final specification—the open standard for single source C++ parallel programming. SYCL is a key programming framework for the ALCF's upcoming exascale system, Aurora. “Our users will benefit from features in the SYCL 2020 specification. New features, such as support for unified memory (USM) and reductions, are important capabilities for programming high-performance-computing hardware,” said Nevin Liber, ALCF computer scientist.
