OpenCL on CPU

Hi,
I’m currently working with openCL on GPU,
I want to know if it’s possible tu run Opencl Kernels on CPUs?
and if it is possible, does the CPU needs to support an Opencl implementation, or any regular CPU would work?

Thanks.

NVidia doesn’t allow you to run OpenCL on cpu. I believe with ATI card/drivers you can.

Thats corrent. You need to install the ATI drivers (stream 2.0.1) to use the CPU with OpenCL. I don’t know, if you need a ATI card for the installation, but for later working on CPU a ATI card is not necessary.
