I take it that if we want to pass a two-dimensional/multidimensional array with data to the GPU, we can use the data representation as a structure and pass the structure?
I tried it through a structure - it worked! I never would have guessed to pass multidimensional arrays this way myself :) Thanks!
I have attached small example, using two-dimensional arrays - it works just fine. The example is a little crooked - but in general it demonstrates the possibility of such a perversion quite well :)
PS: Your UGA + OpenCL - it's just no emotions :) How we used to live - it's creepy to remember...

CL_DEVICE_ANY and CL_DEVICE_GPU obsolete?
Are CL_USE_ANY and CL_USE_GPU_ONLY relevant now?

Yes.
Discovered by Prof. Tychkov's method a mysterious device 1 in my computer, which is faster than CL_USE_ANY and even faster than CL_USE_GPU_ONLY.
What is it? :O

Stats on the board. For all devices. :)

I recommend everyone to try the same way as I did, it is quite possible that you will find a faster device than the helpless discrete graphics. :D
PS. I suspect that CL_USE_ANY and CL_USE_GPU_ONLY are the same - calculation on CPU, but device 1 is my GPU. It's an elementary confusion in the standard constants.
I recommend everyone to mess around with it like I did, you'll probably find a faster device than the useless discrete graphics. :D

Here's what I read! It wasn't in the terminal's help! Tweaked the code to reflect these changes. See what you get. I've got it like this:
23:17:00 SPU time = 1155 ms
23:17:01 Total OpenCL enabled devices: 2
23:17:02 GPU Time #0 = 249 ms
23:17:02 CPY/GPU #0 = 4.639
23:17:03 GPU #1 Time = 265 ms
23:17:03 CPY/GPU #1= 4.358
CPU: GenuineIntel Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz with OpenCL 1.1 (4 units, 2095 MHz, 5990 Mb, version 2.0)
Try using this structure, it didn't work for me (I suspect the second dimension has to be a fixed size, that's why it didn't work for me):
And, for convenience, a function like this to resize both dimensions:
