Is the implication, that applications must use C++, rather than a language people like me can understand? A while ago, I heard the LLNL CTO talk about performance portability for Sierra with the message, I thought, that it was focussed on OpenMP 5, with features driven by CORAL requirements. (He was around for an OpenMP standards meeting, though...) Is it not actually working that way -- if you can talk about such things?
