But CUDA C++ is a single-source programming language incorporating both CPU and GPU parts, so what is the one-to-one replacement for writing a kernel and launching it with the angle bracket syntax? Looking at the whitepaper[0] it looks like there is still some language extension going on to support the single-source case (the __global function). So HIP is also a C++ compiler frontend?
