Heterogeneous Modern C++ with SYCL

on YouTube ↗01h 07m

" summary

Slides claim SYCL 2020 adds ~40 features and aligns with C++17 while remaining backwards compatible, with unified shared memory and group/subgroup algorithms for reductions, class template argument deduction, simpler accessors, and expanded backend interoperability. Implementations like DPC++/ComputeCpp target CUDA, OpenCL, PTX, OpenMP, AMD, TBB and more; multiple features are implemented across vendors and run on real hardware (Perlmutter/Aurora work underway), and kernels may use fusion for performance.
