They're pushing "One API" for programming. They rather have to deliver this time on the Aurora supercomputer.

  Like Roadrunner, they have to deliver something but it doesn't have to be broadly applicable. I expect that Ponte Vecchio and OneAPI will never be used outside of Aurora.

    I wasn't implying confidence, as you might have thought the original Aurora had to be delivered. Everything seems to be labelled "oneAPI" now, like the compiler and MPI.

  Except they are building on top of SYCL, which is already late to the game, as CUDA does C++17 as well, and is polyglot, whereas One API is C++ only and hopes someone else will create bindings, Khronos style in not understanding how to widespread adoption.

    Perhaps I should have said "for what it's worth". I'm not clever enough for C++, but it does seem to be what Livermore, for instance, are committed to. The oneapi propaganda does talk about other bindings, which I haven't looked for. The question might be how it works with OpenMP 5 offload, which was intended for portable performance.
