Help with GPU configuration??

mixed configuration setting.

I have two systems:

1. Intel Core2Duo 3.0Ghz with integrated Intel graphics, Windows XP service pack 3 32-bit. How do I use OpenCL CPU device in this system?

2. Intel Core2Duo, Nvidia graphics (OpenCL 1.0) in Vista 32-bit. How do I enable OpenCL CPU in this system? Nvidia sucks not supporting CPU devices. GPU OpenCL works just fine.

In hardware 1, I have installed APP SDK but still don't have OpenCL

(OpenCL.dll) in Windows system32 folder. Do I need to install any ATI graphics driver? Which one?

 

In hardware 2 how do I install ATI driver, while preserving Nvidia.

Can anyone let me know how? I can do C but not expert in video card configuration.

if you succeed on support opencl for CPU on your config n° 2, please let me know. I've tried it too (AMD CPU, though) with no success.

I did install APP SDK in configuration 1 but found no OpenCL.dll in Windows\system32 folder.

What happened?

kojenku,
Is there any specific reason on why you aren't installing the Intel OpenCL SDK to run on the Intel CPU? You can get it from here:

I downloaded the AMD Display drivers (OpenCL only), and install to configuration 1. Run CLInfo and display the information correctly. This is OpenCL 1.1.

Also in Geek3D GPUCapViewer, the identification correctly shows ATI Stream, 1 CLDevice, and which is Intel Core2Duo.

Intel OpenCL SDK is for Vista and Win7. In configuration 1, I am running Windows XP service pack 3, and Intel SDK is out of question.

AMD OpenCL in configuration 1 works just fine, except that CLInfo tells me there is not out-of-order queue.

Is this normal for all AMD OpenCL CPU?

Well, I have tried several times with raw installation (back up Nvidia OpenCL.dll to other folder). I got either Nvidia or ATI but not both. They do not work together in OpenCL.

Will setting %PATH% environment variable work? I will find out but my gut feeling is a NO.

As I expected, environment variable does not work. OpenCL.dll must reside in windows\system32 folder. Period. Therefore it is a question of either Nvidia or AMD, and I don't think of any way to get both to work together.

Maybe a virtual GPU entry is a way, which just adds a device registry name but not actual graphics functionailty.

did you try recent version of nVidia driver? because older version was incompatible with AMD.
