Intel says CUDA will be nothing but a footnote in computer history

Intel and NVIDIA compete in many different ways. The most notable place we see competition between the two companies is in chipset manufacturing. Intel and NVIDIA also compete in the integrated graphics market where Intel’s integrated graphics chips lead the market.

NVIDIA started competing with Intel in the data processing arena with the CUDA programming language. Intel’s Pat Gelsinger, co-general manager of Intel’s Digital Enterprise Group, told Custom PC that NVIDIA’s CUDA programming model would be nothing more than an interesting footnote in the annals of computing history.

According to Gelsinger, programmers simply don’t have enough time to learn how to program for new architectures like CUDA. Gelsinger told Custom PC, “The problem that we’ve seen over and over and over again in the computing industry is that there’s a cool new idea, and it promises a 10x or 20x performance improvements, but you’ve just got to go through this little orifice called a new programming model. Those orifices have always been insurmountable as long as the general purpose computing models evolve into the future.”

The Sony Cell architecture illustrates the point according to Gelsinger. The Cell architecture promised huge performance gains compared to normal architectures, but the architecture still isn’t supported widely by developers.

Intel’s Larrabee graphics chip will be entirely based on Intel Architecture x86 cores says Gelsinger. The reason for this is so that developers can program for the graphics processor without having to learn a new language. Larrabee will have full support for APIs like DX and OpenGL.

NVIDIA’s CUDA architecture is what makes it possible to process complex physics calculations on the GPU, enabling PhysX on the GPU rather than CPU.

First of for general purpose computing, intel was wrong when it originally abondoned X86 and went with Ia64 (itanium) for 64 bit architecture.
Doesn't that actually put credence to what the Intel guy said? Intel tried the specialized programming model...and failed?

No, that was his point in that it was the wrong direction for general computing, but for specialized purposes you want to squeeze every last bit of performance out of the architecture. Granted, if there are minimal performance losses for making it a bit more like an established model then it may be worth the trade-off.

On that note, isn't CUDA a bit like a handicapped version of C? So it's not all that much of a departure then, eh?

Well,
Whats Ironic? Intel still sells Itanium2. And they still have development team working on them.
EPIC architecture (Itanium2) is designed with same intentions as IBM Cell or nvidia and ATI with their GPU based approach is doing.. Attempting a revolution (instead of an evolution).

And if u read about Itanium, Intel is still convinced that itanium has a future.

And whats makes it funny (for me atleast) is that I code for Itanium based Servers... :)

In my eyes The itanium is to computing what duke nukem 2 is to games.. the continuous promise for the future.. Over 10 years of development constant improvements and reworks.. ;-)
