C++ executors to enable heterogeneous computing in tomorrow's C++ today

Summary of the talk:

For a long time, C++ has been outpaced by other models such as CUDA, OpenMP, OpenCL, HSA, which has offered Heterogeneous computing capability to enable dispatch to GPU, DSP, FPGA or other accelerators.
SG14 is an ISO C++ SG that works on low-latency, in the areas of Games, Financial, Embedded programming. One of their mandate is support of heterogeneous in Native C++, without having to drop to some other model as is needed today.
This talk will describe the first and possibly the most important step towards supporting heterogeneous computing with a description of C++ executors, an interface between concurrency constructs, and the agents/resources, one of which can be a GPU core, or a SIMD unit.  I have led a small group of experts from Google, Nvidia, Codeplay, and NASDAQ, to define a specification to enable separation of concerns in defining where, when, and how execution is done in service of the constructs in existing C++ standard library, Concurrency, Parallelism, Transactional Memory, and Networking TS.
This talk will help you understand these TSes which currently only works on CPUs and how they will tie together in future to enable execution on accelerators based on C++ models we already have today such as SYCL, HPX, Kokkos, and Raja. This will enable native C++ to be usable on machine learning algorithms on future self-driving cars, or medical devices.
