OpenCL Emulation ?

[zak]

Hi Petr, all
i have just tried a thinbasic tbgl EXE , and 2 vc_6 opengl EXE on an old desktop computer with an ordinary intel 82845G graphic controller without opengl hardware support, the three programs run okay, only the vc exe complain that it needs glut32.dll, and when i put it in the same folder the vc 6 exe programs run okay. indeed the thinbasic tbgl program run about the 2/3 same speed visually as on my original opengl hardware supported card pc.
now if opengl programs can run on ordinary pc's without hardware support, then why openCL are not so, i have searched about openCL emulation and it seems there is no such thing except there is a program here:
http://www.techpowerup.com/119073/NVIDIA_CUDA_Emulator_for_every_PC.html?cp=4
called CUDA Emulator Loader (2 MB) when we run it its screen like this:

it askes for the exe containig the openCL code. but what i do not know if we need the openCL run time library, i have geforce 7300 GT, so it is not qualified for openCL, this is why i am asking about emulation, if you have info about that.
thanks

PS: as refered by Petr in the following messages that intel 82845G have an OpenGL support, also by running the utility "OpenGL_GetInfo.tBasic" mentioned below.

Hi Zak,

your graphic card architecture is too far from what would be needed for emulation on GPU, but if you have CPU from AMD, you can just switch the device from GPU to CPU and hapily continue working.

I would like to attach the AMD DLL here, but it would be violation of the licence. Please download the ATI Stream SDK (http://developer.amd.com/gpu/ATIStreamSDK/Pages/default.aspx) (it is huge, I know), find the DLL there (if I remember correctly, it is not named OpenCL.DLL, but it has OpenCL or OCL in name), and then copy the DLL to directory where thinBasic.exe is placed. From this moment you can enjoy OpenCL CPU power (same code as for GPU).

Intel is slightly behind, but I think the implementation from them should appear soon as well.

P.S. Your Intel card should have some older version perfectly enough for TBGL available. Could you run the script from here (OpenGL_GetInfo.tBasic) (http://community.thinbasic.com/index.php?topic=668.msg3885#msg3885)and post what it detected?

[zak]

thank you Petr for the info.
this is the first time i know that the CPU from AMD have this feature over intel cpu. no i have intel cpu.
below is the report produced from OpenGL_GetInfo.

Hi Zak,

we will have to wait for Intel OpenCL implementation then. I was also surprised they did not payed attention to this. But lately, they don't pay attention to any other solutions than their own, with this approach they will not make many friends.

Thanks for the report, maybe you could try it on PC with Intel card, I am quite sure it has the OpenGL support as well.
Your GeForce 7300 is very good card, but sadly it is one generation older than OpenCL requires.

Hi Petr
indeed i have surprised too much to know that my old intel 82845G graphic have an OpenGL support, it is build in, on a celeron intel motherboard and take the needed memory from the system ram.
i have run the OpenGL_GetInfo.tBasic on the old desktop pc and the following is the report, i will add a note to my first post to correct the info.
also the file "OpenGL_GetInfo.tBasic" in the above link due to the site download problems lack the last character "n" in "end functio".
thank you
