  1. You seem to be willfully missing the point. To...

    You seem to be willfully missing the point. To use Apple terms, Vulkan is Metal --- the low-level API. On TOP of this, one can construct various high-level API's that meet different needs. Apple has ...

    The status page
    https://github.com/clang-omp/clang/wiki/Status-of-supported-OpenMP-constructs
    seems to indicate that the official release 3.6 has a LOT of holes in the OMP support, suggesting that...
  3. The future auto market (which I expect they are...

    The future auto market (which I expect they are working on but have nothing to show today) assumes autos kitted out with 12 or so camera-like sensors (so optical cameras, maybe in stereoscopic...
  4. AMD have said that designing an x86 CPU at the...

    AMD have said that designing an x86 CPU at the same performance level as an ARM CPU costs 10x as much.
    So what's the win for nV here? They get into a performance pissing match with Intel that they...
  5. It is not realistic to assume that you, some...

    It is not realistic to assume that you, some random guy on the internet, has seen a huge flaw in this infrastructure that somehow slipped by all the engineers at AMD, ARM, the libJPEG team, etc,...

    It's true that this is hardly a new concept (and that it was provided by the Thread Manager in pre-OSX MacOS).
    That doesn't mean it's a useless concept.
    I made aggressive use of this when I wrote...
  7. Oh for crying out loud. Before you run off on...

    Oh for crying out loud.
    Before you run off on some crazy conspiracy theory, you know that Chandler Carruth, the Clang lead dev, is a Google employee, right?

    For all you know, their primary...

    Your enthusiasm is appreciated, but it's good to be honest here.

    Apart from OpenMP support, GCC has polyhedral optimizations in graphite which are not yet part of LLVM. In theory this is a...

    The network in the building where the server is located (which I am guessing is some university campus somewhere) is down.
    People are aware of it but nothing can be done until the building network...
  10. Modules are already part of Clang. They are...

    Modules are already part of Clang. They are (thank Apple for this...) on track, as far as I can tell, to be part of C++14.
  11. I think it's a reasonable assumption. It's the...

    I think it's a reasonable assumption. It's the way I would bet.
    Apple has SPECIFICALLY stated that Swift code right now is in a state of flux, and they make no promises about backward compatibility....

    Please do share with us the details of this bizarre conspiracy..
    What exactly are the proprietary extensions Apple has added to LLVM?
  13. I agree those will be interesting, but the title...

    I agree those will be interesting, but the title does SAY that it's a GPU test...

    (Personally I'd call it a GL gaming test...

    Apple's first priority for the GPU is how it handles the visual...

    The point is that, for historical reasons, the GPU has been treated as a kind of weird peripheral, not as a kind of CPU that just happens to use a different ISA from the main CPU. Suppose you have a...

    No, he means back-ends. The whole point is that the front-end is language specific, and generates IR. a "neutral" middle part optimizes the IR. Then a back-end generates CPU specific machine...

    What EXACTLY are you claiming?
    Which of
    (a) Dart, RUN ON A BROWSER THAT SUPPORTS NATIVE DART is faster than JS or
    (b) Dart, COMPILED TO JS, is faster than JS?

    If (a), presumably that's only...

    I have no idea why you are so angry. Or for that matter where you got your numbers from.

    Let's LOOK at the numbers:
    iPad Air at 1.4GHz. Geekbench single core rating is 1371:...

    To add to the (remarkably few) facts in this thread, x32 buys you about 10% in performance over x64. That's not bad, especially in contexts like phone and tablet where large address spaces are...
  20. I don't know what benchmarks you're looking at,...

    I don't know what benchmarks you're looking at, but the statements above strike me as very wrong.
    A more accurate claim, IMHO, would be that (averaged over a range of code) the Apple A7 has about...
