Hi, every body!

I have a question about getting cpu device with opencl on ubuntu 11.10.
I have already installed nvidia opencl(cuda) sdk on my computer, and run sample codes successfully.

But when I tried to modify the code and get cpu devices, the number of cpu devices always returns zero!

My question is how to get the cpu device with opencl.

thanks~

You need to have .icd entries in /etc/OpenCL/vendors/ The only way to get them currently is to install the relavent (intel / amd) OpenCL SDKs.

So I have to install intel opencl sdk if I want to use the cpu device.

Then, when I want to use the cpu device, I choose the intel platform;

when I want to use the gpu device, I choose the NV platform.

Are above statements true?

thanks~

This is correct.
