    Can OpenCL run on a single core machine without any GPU?

    Can OpenCL run on a single core machine without any GPU? No parallel programming is expected. Just wanting to run the code. If so, how can I do that?

    Thanks,

    I know the Apple implementation and the AMD implementation both support a CPU device.

    Hi,

    with AMD OpenCL CPU implementation, I managed to run OpenCL code on AMD Sempron 3400+, which is single core.
    The performance on this configuration was not great (highly data parallel task), but usable.
    The same code executed on GeForce 9500GT was about 50x faster.
