Hi Paul, Have you heard of "Julia" language? JFYI, As can be seen in its official page at https://julialang.org/ and a Wikipedia article at https://en.wikipedia.org/wiki/Julia_(programming_language), it looks like one of promising answers to perfbook's Section 2.2 "Parallel Programming Goals". As long as high-performance number crunching is concerned, it claims to have comparable performance to C, with a programming productivity much better than C + MPI. Note: I'm not a user of the language at the moment. I just heard of it at a twitter hashtag #julialang. I'd like you to check it up and (hopefully) update the above mentioned section in perfbook.
