In this talk, we discuss the use of OpenMP as a kernel language (think CUDA or HIP). While OpenMP comes with offloading capabilities, the execution model was different and generally associated with overheads. Further, the user did not have the same level of control, at least not without target-specific builtins. With our new OpenMP extensions, we can match native CUDA (and HIP) codes while retaining the portability of OpenMP as well as interoperability with the existing capabilities.
