You're working from old information. Show me a benchmark where Fortran wins over C or C++ any more. Those days are gone. Here's my line in the sand: https://benchmarksgame-team.pages.debian.net/benchmarksgame/faster/fortran.html As for GPUs, no contest.

Benchmarks are meaningless. I know from experience at looking at the generated assembler code and intel Fortran's SIMD code that it's faster. Take a look at the generated code and then we can discuss it, but not before. I'm not going to beat myself in C when I calculate a 100 million by 100 million matrix in Fortran. ifort will generate SIMD code with CPU autodetection and use machine code seqencing best for that processor, plus in Fortran a matrix is a normal variable type like any other. I'm not beating that with C (and I really know C). And just so you know, my information isn't old, I come from supercomputing.

  > Benchmarks are meaningless. Random anecdotes are meaningless. I've looked at plenty of generated code, and I've written plenty of SIMD assembly too. If you can't measure it, you can't compare it or improve it. There's nothing to discuss.

    So if you looked at it, where are the assembler listings to compare? Let me see, I want to see too! If there is nothing to discuss and you plain refuse to do what I told you, why reply? Until you do exactly what I told you, there is nothing to see here. I have zero tolerance for people who won't listen. Move along, move along.

      It's very weird you have the presentation of an impudent 20 year old but you share an irrational preference for Fortran, which is something I'm only used to seeing in people who are past their mid 50s. "Move along"? You're very full of yourself, and I think that explains why you aren't as smart as you think you are.

        What you are or aren't used to seeing is about relevant to me as the last year's snow. You're free to think whatever the hell you want, that being a basic human right. Move along now, nothing to see here.

  If you can contribute better Fortran programs for those Intel Fortran measurements, please do. https://benchmarksgame-team.pages.debian.net/benchmarksgame/measurements/ifc.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... https://salsa.debian.org/benchmarksgame-team/benchmarksgame/blob/master/CONTRIBUTING.md https://salsa.debian.org/benchmarksgame-team/benchmarksgame/...

    And who will compensate me for my free time spent on that and at which rate per hour in USD? Where and to whom do I send the bill?

      If you don't wish to contribute better Fortran programs for those Intel Fortran measurements, then don't.

        Where does it say that I don't wish to contribute? I asked about pay because my free time isn't worthless to me and I got back a tangential answer. "Hacker" "News" at its finest.

        Seems like you wish to quarrel with someone about something. If you wish to contribute then please follow the instructions; if you don't wish to contribute then have a nice day.
        Annatar 7y ago
        I note how you consistently avoid to discuss monetary compensation for investing my time into contributing. Yeah it pisses me off that you believe my free time is worthless and that you're just entitled to ask someone to donate their time without providing anything in return.
