I though an OpenCL app linked to the nVidia library won't work on ATI GPUs and that the reverse was true as well (an app linked to the ATI library won't run on nVidia GPUs). Or, has OpenCL matured enough such that it is no longer true?
Has anyone tried Intel's OpenCL library for CPUs yet? Is there a coproc class for that as well?
