I read in a lot of places that people were expecting NVidia to ditch CUDA in favor of OpenCL (that is, replace CUDA with OpenCL, as they helped develop it anyway). Lots of people familiar with it said they were basically the same (or, in NVidia-speak, reinforce the same basic ideas), and there was no point in NVidia replicating it with CUDA.

And before the fanboys get here bashing OpenCL as being too complicated: Apple will probably get around that with Objective-C's garbage collection, which is a feature of most modern programming languages (such as C#)]]>Dec 9th 2008 8:15PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
I'd certainly like my graphics card to run more than just games and Folding@Home.]]>Dec 9th 2008 8:20PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:22PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:41PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 9:41PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
If it gets people to switch from endless WoW session to finding a cure for cancer, I'm all for it!]]>Dec 9th 2008 9:45PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 10:14PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 10th 2008 4:21AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:22PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:24PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:25PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
They can handle more than one task at a time, you know.]]>Dec 9th 2008 8:27PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 9th 2008 8:30PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
They are doing 2 fantastic things,

1. Laying the founding blocks for ditching x86 which celebrated its 30th birthday earlier this year.
2. Giving programmers experience with using vast numbers of cores on massively multi-threaded tasks.

Once GPGPU's start coming into mainstream use, Nvidia is going to pretty much dominate the market and rake in the cash since they have already done the vast majority of the R&D now instead of when it becomes nescessary.]]>Dec 9th 2008 8:46PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
There's no need to change the instruction set. If there's a problem at the CPU level, you probably just need a better compiler. GCC, MSVC and the Intel compiler are all pretty good.]]>Dec 10th 2008 12:21AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
These days a Core2Duo chip is about the same price as a 9800GT card. Why not just make a dual CPU motherboard, pop another CPU in there, and forget about the GPU? Just put some extra RAM in there to replace the GPU memory. Graphics cards seem to only have 512MB these days, which is chump change. When you go to play a game, have the OS push all the usual GPU tasks to the second CPU, and not allow any other tasks to be sent to it, unless it's really got a light load.

The only video card we would need would be a tiny board with a DVI/Display Port/HDMI/etc. outputs.]]>Dec 9th 2008 11:53PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
A Core i7 EE could not outperform a GMA X3100 at 3D rendering. Now realize why we want to use a GTX280 for GP. Unbridle power*




... for the right kinda instructions*.]]>Dec 10th 2008 2:34AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
GPUs CAN do gpp, but what they are very good at is at maths and vector based processing. So if you have to do some complex calculations, or a bunch of simple calculations, then you should use a GPU.

If you want to use control structures, comparisons, interrupt based processing, etc, you should use the CPU.

So yes, I do see a bright future for Altivec, eee , sorry, for GPUs.]]>Dec 10th 2008 6:56AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/well yeah, most GPUs will be dead when you put them in water.]]>Dec 10th 2008 12:03AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 10th 2008 12:46AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 10th 2008 8:19AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/]]>Dec 10th 2008 8:43AMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Great great posting!]]>Dec 10th 2008 1:58PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
And AMD/ATI is claiming a 23 minute video conversion (90 minutes of 1080p MPEG-2 video converted to h.264) on a 4850 vs. a 3.0GHz Core 2 Extreme QX9650 taking 4 hours and 23 minutes. A speedup of about 11:1. This one is a Stream spec, but whatever.

So at least for certain jobs, this is a serious amount of acceleration. For my video encoding jobs, like using TivoToGo, this would be a godsend. Obviously the question is whether there is mass adoption and support of this spec across ALL of the video encoding/transcoding programs out there. Videora, ffmpeg, TTG, Roxio, Vegas, Adobe, blah blah blah...]]>Dec 10th 2008 3:59PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/Dec 10th 2008 6:28PMhttp://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/http://www.engadget.com/2008/12/09/nvidia-dishes-about-opencl/
