Intel C/C++ Compiler Beats GCC

They also predict the end to the ubiquitous GNU compiler due to low performance. Many other compiler/platform combinations also compared. A bit pretentious, yet an interesting read."

    Biting at the troll ...

    It's not free software.

    It's free as in beer for uncommercial uses - go ahead and download it yourself. The only problem seems to be that they say it's just for RedHat or TurboLinux. However, it seems like it just puts itself in /opt and leaves things alone, thankfully. They did get it to work under SuSE.

    geometric mean performance on multiple kernels compiled through it reached 47% improvement over GCC.

    The testing didn't involve compiling kernels at all

    I believe this misunderstanding comes from the fact that they called their different benchmarks "kernels" for some reason.

    You, sir, are an idiot.

    Let me get this straight.
    And that, from you, would be a very, very large accomplishment. Unfortunately, you failed.

    Intel is happy that their compiler can beat another compiler? I'd hope so... They designed the damn chips, had a head start, have cash money to buy a few smart compiler dudes .. you'd think they'd have enough pride to work on a compiler until it was the best it could be.
    Probably. They invest a lot of money in these things. About the only point right you got in your whole damned convoluted post.

    It is interesting to see Intel pick on GCC. They are in the CHIP BUSINESS... A compiler (any compiler) helps them.
    Okay. So. You COMPLETELY miss the fact that this was Open Magazine. How convenient. (Guess who didnt read the article... *gasp*)

    You'd think THEY would be the ones to release a compiler into open source so they could get the rest of the world looking at how to do even more optimizations for their chips.
    As indeed they have. Check out egcs.

    GCC has been out there for well over a decade. Open to anyone to improve ... or just stare at.
    No prize for guessing which one of those YOU did

    Intel could show us all how to make a better compiler. Open up their source code... but someone might improve on their techniques and that would make them sad. So, instead they berate a compiler that has done them only a service.
    Berate? Oh yeah, that was open magazine. (again). My bad.

    Just my thoughts. Yours may vary.
    And that is pretty bloody likely.

    How in bloody hell is this off topic??? It's about the damn article, it even has a bleeding quote from the damn article! Or are you the one who decides which parts of the article we are supposed to talk about? Because no one told me.
