What Hacker News says?
If you want to use C today you need a really good excuse. The tradeoff between security and performance is simply not there anymore. Unless you write on an embedded system, a game, or a high performance number crunching application, C is premature optimisation. And even in the above we see drastic changes today, embedded systems have become so powerful that they can run scripting languages ( http://www.eluaproject.n…

HN discussionUgh, MPI. I guess it uses MPI behind the scenes but MPI is the wrong level of abstraction for most things, for today. This[0] convinced me of that. [0] https://www.dursi.ca/post/hpc-is-dying-and-mpi-is-killing-it...

HN discussionSomewhat tangential, but you may be interested in this essay on "HPC is dying and MPI is killing it" http://www.dursi.ca/hpc-is-dying-and-mpi-is-killing-it/ . There were many comments here on HN, at https://news.ycombinator.com/item?id=9335441 . The essay also has a couple of followups. It really is an excellent essay. The author suggests GASNet, Charm++, and several other things that would be comparable to MPI.

HN discussionI enjoyed this piece when it came out in 2015. I think it's worth a read for those who haven't seen it before. The previous HN comments are at https://news.ycombinator.com/item?id=9335441 . There's also a followup essay at http://www.dursi.ca/objections-continued/ . Looking now, I see the author discussed the topic further in a podcast at http://www.rce-cast.com/Podcast/rce-97-jonathan-dursi.html . I have not yet li…
